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
