Question

Which one of the following equations illustrates the commutative property?

8 + 3 = 4 + 7
If 3 + 5 = a, then a = 3 + 5
2 + b = b + 2
3(2 + 5) = 6 + 15

Answer 1

I THINK ITS 2 + b = b + 2

Answer 2

. A binary operation * on a set S is called commutative if:
x * y = y * x {for all }x,y in S

Answer 3

so it's 2+b=b+2
