Broken Calculator (Posted on 2005-01-20) Difficulty: 3 of 5
You have a calculator whose multiplication button is broken. The only operations that work are addition (x+y), subtraction (x-y), and reciprocation (1/x).

Can you use this calculator to multiply two numbers?

"Multiply by 1/(x+y)"
... but this won't work because we can't multiply.
