Answer explanation

The square of a positive integer is always positive.

The property which states that changing the order of the factors does not affect the product:

a x b = b x a

• Commutative Property of Addition

• Commutative Property of Multiplication

• Associative Property of Addition

• Associative Property of Multiplication

This property states that adding first before multiplying or distributing the factor to each addend will give same answer:

a ( b + c ) = a ( b ) + a ( c )

• Distributive Property

• Commutative Property

• Associative Property of Addition
