Likewise, 1 can be multiplied by any number without changing the value of that number. associative property - ANSWER - The property that under certain operations in a multi-step expression, the computations may be done in any order. Commonly represented as (a + b) + c = a + (b + c). Addition and multiplication both have this property, but subtraction and division do not. perfect square - ANSWER - The product of any integer with itself yields this.
