---|---|
a + b = b + a | commutative property of addition |
a x b = b x a | commutative property of multiplication |
(a + b) + c = a + (b + c) | associative property of addition |
(a x b) x c = a x (b x c) | associative property of multiplication |
a + 0 = 0 + a = a | additive identity |
a x 1 = 1 x a = a | multiplicative identity |
a x 0 = 0 x a = 0 | multiplicative property of zero |
7 + 3 = 3 + 7 10 = 10 | commutative property of addition |
6 x 4 = 4 x 6 24 = 24 | commutative property of multiplication |
(6 + 4) + 3 = 6 + (4 + 3) | associative property of addition |
(7 x 5) x 2 = 7 x (5 x 2) 70 = 70 | associative property of multiplication |
