Question

9. Given that a = (-10), b = 7 and c = (-3), verify that addition is commutative
and associative. Also show that subtraction is neither commutative nor associative. plz explain it​

Answer 1

The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.
