How is subtraction like division?

Answer 1

It's basically the same concept. Like subtraction is the opposite of addition, and division is the opposite of multiplication. Just the reverse. Kind of hard to explain.... ask your teacher!

Answer 2

Neither are commutative: a - b does not equal b - a, and a/b does not equal b/a.

Neither is associative: (a - b) - c does not equal a - (b - c), and (a/b)/c does not equal a/(b/c).
