Step-by-step explanation:
a + b = b + a - commutative property for addition
ab = ba - commutative property for multiplication
a - b = b - a - FALSE
a/b = b/a - FALSE
(a + b) + c = a + (b + c) - associstive property for addition
(a - b) - c = a - (b - c) - FALSE
a(b + c) = ab + ac - distributive property
False statements (examples):
3 - 4 = -1
4 - 3 = 1
-1 ≠ 1
4/2 = 2
2/4 = 1/2
2 ≠ 1/2
(2 - 3) - 4 = -1 - 4 = -5
2 - (3 - 4) = 2 - (-1) = 2 + 1 = 3
-5 ≠ 3
