Properties for real numbers

inverse prop of addition .     7 + -7 = 0

inverse prop of multiplication .      1/2 (2) = 1

identity property of add        7 + 0 = 7

identity property of mult .     7x1 = 7

distributive .  8x  +  3x = 11x

associative property of addition ( 7 + 2) + 8 = 7 + (2+ 8)

associative property of multiplication  (7x2)x10 = 7x(2x10)

commutative property of addition .  9 + 3 = 3 + 9
