Changing the order of addends does not change the sum. Ex. 6 + (-2) = -2 + 6; 4 = 4 true
and

Changing the grouping of the addends does not change the sum. Ex. (-6 +2) + 3 = -6 + (2+3)
-4+3 = -6+5
-1 = -1 true
Changing the grouping of the factors does not change the product. Ex. (-6 x 2)3 = -6 (2 x 3)
(-12)3 = -6(6)
-36 = -36 true

Multiplying a sum by a number is the same as multiplying each addend by that number in adding the two products.
Ex. -3(-4+5) = -3(-4)+(-3)(5)
-3(1) = 12 + (-15)
-3 = -3 true
