    CONCLUSION
    The State presented sufficient evidence to establish beyond
    a reasonable doubt Samantha’s status as being habitually truant
    under § 43-247(3)(b). We reject her argument that the State
    was first required to show that her school provided the services
    contemplated by § 79-209(2), and we hold that § 79-209 does
    not impose any preconditions upon the juvenile court’s exclu-
    sive and original jurisdiction under § 43-247(3)(b). The judg-
    ment of the juvenile court is affirmed.
    Affirmed.

    INTRODUCTION
    The Nebraska Department of Revenue (Department) and
    Douglas Ewald, in his capacity as the State Tax Commissioner
    (collectively the State), appeal, and Kerford Limestone Co.
    (Kerford) cross-appeals from the district court’s order in these
    tax protest proceedings. Kerford purchased a motor grader for
    use in its manufacturing business and claimed an exemption
    from sales and use tax on the purchase under Neb. Rev. Stat.
    § 77-2704.22 (Reissue 2009). The commissioner found that
    Kerford had failed to prove that the motor grader was exempt
    manufacturing machinery and equipment, as defined in Neb.
    Rev. Stat. § 77-2701.47 (Supp. 2005).
    On appeal, the district court reversed the commissioner’s
    determination that to qualify for an exemption, Kerford needed
    to establish that more than 50 percent of the motor grad-
    er’s total use was in manufacturing. The court affirmed the
    Nebraska Advance Sheets
    KERFORD LIMESTONE CO. v. NEBRASKA DEPT. OF REV.	655
    Cite as 
    287 Neb. 653
    commissioner’s determination that Kerford’s use of the motor
    grader to maintain “haul roads” was not a use that qualified
    the motor grader as exempt under § 77-2701.47. The court
    remanded the proceedings for a determination whether use of
    the motor grader to maintain inventory stockpile areas quali-
    fied it for an exemption. We affirm in part, and in part reverse
    and remand with direction.
    FACTS
    In January 2006, Kerford purchased a CAT 160H motor
    grader for use in its limestone mining and manufacturing
    business. Claiming that the motor grader was exempt from
    taxation as manufacturing machinery and equipment under
    §§ 77-2701.47 and 77-2704.22, Kerford did not pay sales or
    use tax on the purchase. Per stipulation of the parties, Kerford
    uses the motor grader in its business “to maintain haul roads
    in and outside of the mine” and to maintain “inventory stock-
    pile areas.”
    In December 2006, Kerford received a notice of deficiency
    determination from the Department, reflecting that Kerford
    owed $24,614 in sales and use taxes, interest, and penalties for
    various purchases between June 1, 2003, and May 31, 2006,
    including the motor grader. The parties reached an agreement
    on all deficiencies except that of use tax on the motor grader,
    which totaled $14,190, not including interest or penalties.
    Kerford filed a written protest as to that amount.
    Prior to Kerford’s protest, the commissioner had issued a
    revenue ruling interpreting the definition of manufacturing
    machinery and equipment in § 77-2701.47 for purposes of an
    exemption under § 77-2704.22. See Nebraska Department of
    Revenue Ruling 1-05-1 (Oct. 12, 2005). This revenue ruling
    provided in part: “If machinery and equipment has uses in addi-
    tion to its manufacturing use, the manufacturing use must
    be greater than 50% of total use to qualify for the exemp-
    tion.” 
    Id. (emphasis in
    original). After the Department sent the
    notice of deficiency determination but while Kerford’s protest
    was pending, the Department’s regulations were amended to
    include the content of Revenue Ruling 1-05-1. See 316 Neb.
    Admin. Code, ch. 1, § 107.07 (2011).

    656	287 NEBRASKA REPORTS
    At a hearing on Kerford’s protest, Kerford challenged
    the Department’s interpretation that § 77-2701.47 restricted
    application of the manufacturing machinery and equipment
    exemption to machinery and equipment used for manufactur-
    ing more than 50 percent of the time. Kerford argued that the
    Department’s interpretation was contrary to the Legislature’s
    intent to provide a broad exemption, as shown by the plain lan-
    guage of the statute. Kerford also argued that both of the motor
    grader’s uses—to maintain haul roads and to maintain inven-
    tory stockpile areas—were related to “‘transporting, convey-
    ing, . . . or storing’ raw materials in manufacturing” (ellipsis in
    original) and thus qualified the motor grader as manufacturing
    machinery and equipment under § 77-2701.47(1)(b). According
    to Kerford, using the motor grader to maintain inventory
    stockpile areas also qualified as a use in manufacturing under
    § 77-2701.47(1)(d).
    After the hearing, the commissioner upheld the imposition
    of use tax on the motor grader. The commissioner defended
    the Department’s interpretation of § 77-2701.47 as “a reason-
    able construction in light of case law on other exemptions to
    taxation.” He determined that under the Department’s inter-
    pretation, Kerford was not entitled to an exemption for the
    motor grader’s use to maintain inventory stockpile areas,
    because Kerford had not met its burden of proving “how
    much the motor grader is used to maintain such inventory
    piles.” Because Kerford did not establish what percentage
    of the motor grader’s total use was devoted to maintaining
    inventory stockpile areas, the commissioner did not explicitly
    discuss whether such use was a use in manufacturing under
    § 77-2701.47. However, the commissioner determined that the
    motor grader’s use to maintain haul roads was not a use in
    manufacturing. He reasoned that such use was “more in line
    with the support services that are included in the non-exempt
    list of assets” in § 77-2701.47(2).
    Kerford appealed by filing a petition on appeal and com-
    plaint for reversal with the district court. After a hearing, the
    court reversed the commissioner’s order in part, affirmed in
    part, and remanded for further proceedings. It reversed the
    Nebraska Advance Sheets
    KERFORD LIMESTONE CO. v. NEBRASKA DEPT. OF REV.	657
    Cite as 
    287 Neb. 653
    commissioner’s determination that Kerford was required to
    show that the motor grader was used in manufacturing at least
    50 percent of the time. Because § 77-2701.47 “includes no
    language whatsoever specifying—in mathematical terms or
    otherwise—the amount of time which equipment or machinery
    must be used in manufacturing to qualify for the exemption,”
    the court found Revenue Ruling 1-05-1 to be “arbitrary” and
    “wholly unsupported by a plain reading of . . . § 77-2701.47(1)”
    and declared Revenue Ruling 1-05-1 to be “invalid.”
    The district court next considered the motor grader’s use to
    maintain haul roads. It affirmed the commissioner’s determina-
    tion that maintaining haul roads was not an exempt use within
    the plain meaning of § 77-2701.47. The court reasoned that
    when used to maintain haul roads, the motor grader “neither
    has direct contact with raw materials, components, or finished
    products nor is it used to guide, control, operate, or measure
    the manufacturing process.”
    Finally, the district court addressed the motor grader’s use
    to maintain inventory stockpile areas. Because the commis-
    sioner had not addressed whether such use qualified as a use
    in manufacturing, the court remanded for further proceed-
    ings on this issue. It ordered the commissioner to consider on
    remand “whether use of the motor grader to maintain inventory
    piles qualifies the motor grader as ‘manufacturing machin-
    ery and equipment’ under either . . . § 77-2701.47(1)(b) or
    § 77-2701.47(1)(d).”
    The State timely appeals, and Kerford cross-appeals.
    Pursuant to our statutory authority to regulate the dockets of
    the appellate courts of this state, we moved the case to our
    docket. See Neb. Rev. Stat. § 24-1106(3) (Reissue 2008).
    ASSIGNMENTS OF ERROR
    The State assigns, restated, that the district court erred
    in (1) finding invalid the Department’s interpretation of
    § 77-2701.47 that machinery or equipment was not exempt
    under that statute unless more than 50 percent of the total use
    was for use in manufacturing; (2) remanding for consider-
    ation whether use of the motor grader to maintain inventory
    Nebraska Advance Sheets
    658	287 NEBRASKA REPORTS
    stockpile areas qualified the motor grader as exempt, because
    the court was not authorized by Neb. Rev. Stat. § 84-917(6)(b)
    (Cum. Supp. 2012) to make such remand in combination with
    reversal on another issue; and (3) remanding for a determina-
    tion whether using the motor grader to maintain inventory
    stockpile areas qualified the motor grader for an exemption
    under § 77-2701.47.
    On cross-appeal, Kerford assigns, reordered and restated,
    that the district court erred by (1) determining that use of the
    motor grader to maintain haul roads was not an exempt use
    under § 77-2701.47(1)(b), because such conclusion was incon-
    sistent with the statutory language, and (2) giving deference to
    the commissioner’s determination that use of the motor grader
    to maintain haul roads did not qualify the motor grader for an
    exemption under § 77-2701.47.

    ANALYSIS
    Department’s Interpretation
    of § 77-2701.47
    [4,5] The State argues that the district court erred in con-
    cluding that the Department’s interpretation of § 77-2701.47,
    embodied in Revenue Ruling 1-05-1, was invalid. This argu-
    ment presents a question of statutory interpretation, about
    which we must “reach an independent conclusion irrespec-
    tive of the decision made by the court below.” See 
    Smalley, 283 Neb. at 550
    , 811 N.W.2d at 251. In this examination of
    the statute, we are governed by the following principles. An
    appellate court will not resort to interpretation to ascertain
    the meaning of statutory words which are plain, direct, and
    unambiguous. Holdsworth v. Greenwood Farmers Co-op, 
    286 Neb. 49
    , 
    835 N.W.2d 30
    (2013). When interpreting statutes,
    an appellate court will not read into a statute a meaning that is
    not there. 
    Id. The issue
    is whether Kerford’s purchase and use of the
    motor grader to maintain haul roads and inventory stockpile
    areas qualified the motor grader as manufacturing machinery
    and equipment, which machinery and equipment is exempt
    from sales and use tax under §§ 77-2701.47 and 77-2704.22.
    Because the motor grader was not a hand tool, office equip-
    ment, a vehicle registered for operation on Nebraska roads
    and highways, or “computers, software, and related peripheral
    equipment,” the motor grader was not specifically excepted
    from the definition of manufacturing machinery and equip-
    ment. See § 77-2701.47(2). Thus, we focus our analysis on the
    definition provided in § 77-2701.47(1). We also note that the
    motor grader met the requirement in § 77-2701.47(1) of being
    purchased by “a person engaged in the business of manufactur-
    ing.” For purposes of tax exemptions, corporations are included
    within the statutory definition of “person.” See Neb. Rev. Stat.
    § 77-2701.25 (Reissue 2009). Additionally, the parties stipu-
    lated that Kerford is “in the business of manufacturing” and
    that Kerford purchased the motor grader in that capacity. As
    Nebraska Advance Sheets
    660	287 NEBRASKA REPORTS
    such, the question whether the motor grader is exempt comes
    down to its use.
    In our examination whether the motor grader was exempt,
    we must consider whether § 77-2701.47(1) required any par-
    ticular percentage of the motor grader’s total use to be in
    manufacturing in order for the motor grader to qualify as man-
    ufacturing machinery and equipment. The Department claimed
    that § 77-2701.47(1) exempted machinery or equipment only
    if its use in manufacturing constituted more than 50 percent
    of the total use. The district court concluded this interpreta-
    tion was contrary to the plain language of § 77-2701.47(1).
    We agree.
    Section 77-2701.47(1) provides that manufacturing machin-
    ery and equipment includes “any machinery or equipment pur-
    chased, leased, or rented by a person engaged in the business
    of manufacturing for use in manufacturing.” It does not set
    forth what percentage of use must be in manufacturing in order
    for machinery or equipment to be exempt. The plain meaning
    of the phrase “any machinery or equipment purchased, leased,
    or rented . . . for use in manufacturing” is that any amount of
    use in manufacturing brings machinery or equipment within
    the statutory definition. Thus, to fall within the definition of
    manufacturing machinery and equipment in § 77-2701.47(1),
    machinery or equipment purchased by a “person” engaged in
    the business of manufacturing must meet only one requirement:
    any amount of its use is in manufacturing.
    The statute establishes no requirements on what percentage
    of total use of machinery or equipment must be “for use in
    manufacturing” in order for the purchase of such machinery or
    equipment to be exempt. By requiring machinery and equip-
    ment to be used in manufacturing more than 50 percent of the
    time, the Department added language to its ruling which is not
    found in § 77-2701.47(1). We will not add a requirement for
    the exemption that is not there.
    [6] But the State argues that the district court’s interpretation
    of § 77-2701.47(1) added language to the statute. We disagree.
    The absence of any qualifying language in the phrase “any
    machinery or equipment purchased, leased, or rented . . . for
    use in manufacturing” indicates that no temporal qualifications
    Nebraska Advance Sheets
    KERFORD LIMESTONE CO. v. NEBRASKA DEPT. OF REV.	661
    Cite as 
    287 Neb. 653
    were intended. “[T]he intent of the Legislature may be found
    through its omission of words from a statute as well as its
    inclusion of words in a statute.” Lozier Corp. v. Douglas Cty.
    Bd. of Equal., 
    285 Neb. 705
    , 714, 
    829 N.W.2d 652
    , 660 (2013).
    Because no time-based qualifications are imposed upon the
    uses that bring machinery or equipment within the meaning of
    the definition in § 77-2701.47(1), any amount of use in manu-
    facturing is sufficient.
    If the Legislature had intended to impose temporal qualifi-
    cations upon the language of § 77-2701.47(1) in the manner
    contemplated by the Department, the Legislature could have
    provided that to qualify for an exemption, the use of machinery
    or equipment in manufacturing must be more than 50 percent
    of the total use. Indeed, similar language is found in other tax
    exemption provisions. Under Neb. Rev. Stat. § 77-2704.13(1)
    (Reissue 2003), the purchase of certain energy sources or fuels
    is exempt from sales and use tax “when more than fifty percent
    of the amount purchased is for use directly in irrigation or
    farming.” Sections 77-2704.13(1) and 77-2701.47(1) are both
    located within chapter 77, article 27, of the Nebraska Revised
    Statutes. The language of the former statute contains a thresh-
    old of more than a 50-percent use to qualify for an exemp-
    tion, but the latter does not mention any time-based thresholds
    or qualifications.
    [7] This fact is a significant indication of the Legislature’s
    intent in enacting § 77-2701.47(1). “We have observed that
    the ‘Legislature is presumed to know the general condition
    surrounding the subject matter of the legislative enactment,
    and it is presumed to know and contemplate the legal effect
    that accompanies the language it employs to make effective
    the legislation.’” In re Invol. Dissolution of Wiles Bros., 
    285 Neb. 920

    276 Neb. 686
    , 
    757 N.W.2d 194
    (2008)). Given that other statutory exemptions from sales
    and use tax require the exempt use of property to be more than
    50 percent of the total use, we interpret the absence of such
    language in § 77-2701.47(1) to indicate that the Legislature
    intended to exempt machinery or equipment if it has any
    amount of use in manufacturing.
    Nebraska Advance Sheets
    662	287 NEBRASKA REPORTS
    The Department’s interpretation of § 77-2701.47(1) was
    contrary to the plain language of the statute. The district court
    did not err in reversing the commissioner’s decision based on
    such interpretation.
    Motor Grader’s Use
    in M anufacturing
    The next question is whether Kerford used the motor grader
    in manufacturing. The parties have stipulated that Kerford is
    “in the business of manufacturing” pursuant to § 77-2701.47(1)
    and that Kerford purchased the motor grader in that capacity.
    The parties also stipulated that Kerford has used the motor
    grader “to maintain haul roads in and outside of the mine” and
    to maintain “inventory stockpile areas.”
    Kerford argues that its stipulated use of the motor grader to
    maintain inventory stockpile areas qualified as a use in manu-
    facturing under § 77-2701.47(1)(d), which provides that the
    definition of manufacturing machinery and equipment includes
    “[m]achinery or equipment for use in manufacturing to main-
    tain the integrity of the product . . . .” Whether the statutory
    language “to maintain the integrity of the product” encom-
    passes the specific act of maintaining inventory stockpile areas
    is a question of law.
    The commissioner denied Kerford’s exemption without spe-
    cifically addressing whether use of the motor grader to main-
    tain inventory stockpile areas was generally a use in manufac-
    turing or, more specifically, a use that maintained the integrity
    of the product. He determined that the motor grader’s use
    to maintain haul roads was not a use in manufacturing. But
    because the commissioner interpreted § 77-2701.47(1) as pro-
    viding an exemption only if more than 50 percent of the total
    use was in manufacturing and because Kerford failed to prove
    that the motor grader’s use to maintain inventory stockpile
    areas met such a threshold, he denied the exemption based
    on Kerford’s lack of proof, without making an explicit find-
    ing whether maintaining inventory stockpile areas was a use
    in manufacturing.
    In the absence of an express finding by the commissioner on
    this issue, the district court did not address whether the motor
    Nebraska Advance Sheets
    KERFORD LIMESTONE CO. v. NEBRASKA DEPT. OF REV.	663
    Cite as 
    287 Neb. 653
    grader’s use to maintain inventory stockpile areas was a use in
    manufacturing that exempted the motor grader from taxation.
    Instead, it remanded this question to the commissioner.
    [8] The district court’s decision to remand for a determina-
    tion whether maintaining inventory stockpile areas was an
    exempt use did not conform to the law. Under § 84-917(5)(a),
    the district court was required to conduct a review of the com-
    missioner’s decision “de novo on the record of the agency.”
    See, also, Nothnagel v. Neth, 
    276 Neb. 95
    , 
    752 N.W.2d 149
    (2008). In a review de novo on the record, the district court
    is required to make independent factual determinations based
    upon the record, and the court reaches its own independent
    conclusions with respect to the matters at issue. JCB Enters.

    275 Neb. 797
    , 
    749 N.W.2d 873
    (2008). Once the district court interpreted § 77-2701.47(1) as
    exempting machinery or equipment with any amount of use in
    manufacturing, the legal issue before the court was whether
    maintaining inventory stockpile areas was a use in manufactur-
    ing under § 77-2701.47(1)(d).
    The district court was faced with not only the legal ques-
    tion whether maintaining inventory stockpile areas was a use
    in manufacturing but also the commissioner’s conclusion on
    this issue. Although the commissioner did not state whether
    maintaining inventory stockpile areas was a use in manufactur-
    ing, his conclusion on this legal issue was implicit within his
    order. The commissioner did not expressly find that maintain-
    ing inventory stockpile areas was a use in manufacturing but
    instead focused on whether such use comprised more than 50
    percent of the motor grader’s total use.
    Because the commissioner found Kerford had failed to show
    that the motor grader’s use to maintain inventory stockpile
    areas was more than 50 percent of the total use, he had to
    have determined that maintaining inventory stockpile areas
    was a use in manufacturing. A contrary conclusion would
    have negated the need to consider whether the maintenance of
    inventory stockpile areas comprised more than 50 percent of
    the motor grader’s total use. Furthermore, if the commissioner
    had not concluded that the use to maintain inventory stockpile
    areas was a use in manufacturing, he would have found that

    neither use qualified the motor grader for tax-exempt status.
    Notably, the commissioner stated that only one of the motor
    grader’s uses—to maintain haul roads—did not qualify as a use
    in manufacturing. Therefore, the issue and the commissioner’s
    conclusion were directly before the court.
    Because the use of the motor grader to maintain inven-
    tory stockpile areas was before the district court and because
    the commissioner implicitly addressed this legal question, the
    court should have decided this issue upon its de novo review
    of the record. It was error to remand for further proceedings.
    We now decide whether maintaining inventory stockpile
    areas qualified the motor grader for the manufacturing machin-
    ery and equipment exemption. We conclude that such use was
    an exempt use under § 77-2701.47(1). The motor grader fell
    within the definition of manufacturing machinery and equip-
    ment because it was used “to maintain the integrity of the
    product.” See § 77-2701.47(1)(d).
    The “stockpile areas” to which this stipulation referred were
    piles of rocks that Kerford accumulated when the company
    produced limestone faster than it could be sold. The piles were
    separated according to the gradation of the limestone and con-
    stituted Kerford’s inventory. The parties agree that the motor
    grader maintained the inventory stockpile areas by pushing
    rocks that slid off the piles back into the appropriate piles.
    Kerford’s evidence showed that keeping rocks in piles served
    two purposes: (1) to keep separation between the piles and (2)
    to prevent loss of rocks. The State does not dispute these pur-
    poses, but describes the motor grader’s general function as
    “cleaning” through the “movement of loose rocks.” Brief for
    appellants at 26.
    Whether labeled as cleaning or loss prevention, the motor
    grader’s use around the inventory stockpile areas was a use that
    maintained the integrity of the product produced by Kerford. A
    product has integrity when it is in “an unimpaired or unmarred
    condition” that is in “entire correspondence with an original
    condition.” Webster’s Third New International Dictionary of
    the English Language, Unabridged 1174 (1993). The State pro-
    poses a similar definition of integrity—“‘sound, unimpaired, or
    perfect condition.’” Brief for appellants at 26.

    Cite as 
    287 Neb. 653
    Kerford manufactured limestone and limestone aggregate
    that were sold in bulk and in different sizes. In regard to any
    particular size of limestone, the aggregate remained in the orig-
    inal and unmarred condition only so long as it stayed grouped
    with other rocks of the same size. In other words, the integrity
    of Kerford’s product depended upon keeping rocks sorted
    according to their sizes. Having the motor grader push rocks
    back into piles ensured both that rocks remained in the appro-
    priate piles according to each rock’s size and that customers
    who ordered limestone of a particular size received rocks of the
    right gradation. Thus, by keeping the rocks in their respective
    piles, the motor grader maintained the integrity of Kerford’s
    limestone and limestone aggregate products.
    Because Kerford used the motor grader to maintain the
    integrity of its products as they were stored in inventory stock-
    piles, the motor grader fell within the definition of manufactur-
    ing machinery and equipment in § 77-2701.47(1)(d). As such,
    under § 77-2704.22, Kerford was entitled to an exemption from
    sales and use tax on the purchase of the motor grader.
    [9] We therefore reverse that portion of the district court’s
    order that remanded this issue for further proceedings before
    the commissioner. We remand the cause to the district court
    with direction to enter an order granting Kerford the exemp-
    tion. Because we reverse the district court’s decision to remand,
    we do not address whether the district court had the authority
    under § 84-917(6)(b) to order such remand. An appellate court
    is not obligated to engage in an analysis that is not necessary
    to adjudicate the case and controversy before it. Holdsworth

    Cross-Appeal
    In its cross-appeal, Kerford alleges the district court’s deter-
    mination that the motor grader’s use to maintain haul roads did
    not entitle Kerford to an exemption was error and should be
    reversed. Specifically, Kerford argues that this portion of the
    court’s order should be reversed, because in it, the court imper-
    missibly deferred to the commissioner’s determination, ignored
    the evidence, and applied § 77-2701.47(1)(b) in a manner
    Nebraska Advance Sheets
    666	287 NEBRASKA REPORTS
    inconsistent with the statutory language. Kerford asserts that
    use of the motor grader to maintain haul roads was a use in
    manufacturing that made the motor grader exempt from sales
    and use tax.
    Whether or not maintaining haul roads was a use in manu-
    facturing, the motor grader was exempt from sales and use
    tax, because it was used in manufacturing when maintaining
    inventory stockpile areas. And under § 77-2701.47(1), any
    amount of use in manufacturing is sufficient to qualify for
    an exemption.
    An appellate court is not obligated to engage in an analysis
    that is not necessary to adjudicate the case and controversy
    before it.

    . Therefore, we do not consider
    whether the maintenance of haul roads was an exempt use.
    CONCLUSION
    For the reasons set forth, we affirm the judgment of the
    district court to the extent it rejected the Department’s inter-
    pretation of § 77-2701.47 as “wholly unsupported by” the
    statutory language. However, because Kerford’s use of the
    motor grader to maintain inventory stockpile areas was a
    use in manufacturing, we reverse that portion of the district
    court’s order that remanded the cause for further proceedings
    before the commissioner and we remand to the district court
    with direction to enter an order granting Kerford an exemp-
    tion from sales and use tax on its purchase of the motor
    grader. We do not address the district court’s determination
    that use of the motor grader to maintain haul roads was not a
    use in manufacturing.
    Affirmed in part, and in part reversed
    and remanded with direction.
