Question 256173
<font face="Garamond" size="+2">

I don't know what a "communitive" property is.  Now there is Community Property, which is that which is owned by both husband and wife in some states.  But I don't think that is what you mean.  Then there is the Commutative Property of Multiplication which says that the order of factors in a multiplication doesn't matter.  You <i>would not</i> use the Commutative Property to solve a multiplication product such as *[tex \LARGE 4\,\cdot\,2].  You <i>would</i> use the Commutative Property to assure yourself that the result is 8 regardless of whether you perform *[tex \LARGE 4\,\cdot\,2] or *[tex \LARGE 2\,\cdot\,4]
