Commutative property of addition

Add

You can use properties of operations to write equivalent expressions. Here are some common properties:

Commutative property of addition	a + b = b + a
Commutative property of multiplication	a b = b a
Associative property of addition	( a + b ) + c = a + ( b + c )
Associative property of multiplication	( a b ) c = a ( b c )
Distributive property	a ( b + c ) = a b + a c

Look at the first two expressions.
