(5 × 7) × ? = 5 × (7 × ?) is an example of a property of multiplication. Which statement describes the property?
This is the associative property. You are simply moving the groups around. The first group is equal to the second by means of the associative property of multiplication is the statement. An easy way to remember it is, Agriculture starts with AG. So do the first letters of 'associate' and 'groups'. :) Rana
