Definition
	associative property: This property applies both to multiplication and addition and states that you can group several numbers that are being added or multiplied (not both) in any way and yield the same value. In mathematical terms, for all real numbers a, b, and c, (a+b)+c=a+(b+c) or (ab)c=a(bc).

 

	Sentence- add parentheses to the addition question so we will know which numbers you added first.
