Create an ontology for a simple mathematical ques

Question

I want a help to create an ontology for a simple mathematical question in protege. Question is like this,

"There are 5 boxes with 8 pencils, 6 boxes with 2 pencils, 4 boxes with 3 pencils.How many pencils are there?"

The quantity and the name of the Items can be changed. I just want a help, how to get a pattern to represent this question in protege.

This is a part of my ontology. But it doesnt represnt the quantity with respect to the each item quantity sets.

<!-- Item1 -->

<owl:NamedIndividual rdf:about="http://www.semanticweb.org/imesha/ontologies/2015/7/untitled-ontology-26#Item1">

Here is the part of the ontology with instances.

<owl:NamedIndividual rdf:about="http://www.semanticweb.org/imesha/ontologies/2015/7/untitled-ontology-26#Item1">
    <rdf:type rdf:resource="http://www.semanticweb.org/imesha/ontologies/2015/7/untitled-ontology-26#Item"/>
    <Item1_Name rdf:datatype="http://www.w3.org/2001/XMLSchema#string">Box</Item1_Name>
    <Item1_Quantity rdf:datatype="http://www.w3.org/2001/XMLSchema#integer">4</Item1_Quantity>
    <Item1_Quantity rdf:datatype="http://www.w3.org/2001/XMLSchema#integer">5</Item1_Quantity>
    <has rdf:resource="http://www.semanticweb.org/imesha/ontologies/2015/7/untitled-ontology-26#Item2"/>
</owl:NamedIndividual>
