This is called commutative property,

This is called associative property.(2) b) (y + 4) + 12 = y + (4 + 12) Inverse

I think you are missing something.(2) c) where x ≠ 0 Commutitative

(2) d) Additive

(2) e) 5(7x + 2) = 5(7x) + 5(2) ?Left-distributive. (But it really does not matter for commutative rings).
