Let R be a commutative ring with 1, i.e, on R we have two binary operations (addition and multiplication) and the Rules of Arithmetic (A1) - (A5) and (M1) - (M4) hold. Please solve the attached questions. Thank you!

1. State the Cancellation Axiom for the multiplication.
2. Show, justifying each step, that the Cancellation Axiom holds if and
only if R has no zero-divisors, i.e., if a, b e R and a xb= 0, then a = 0
or b = 0.
