Four numbers
(1) (5) (6) (7)

The object is to define an equation that will yield 21.

Can do:
1. Utilize all forms of basic math operations (i.e. *, + , - , /). All other operations not allowed.
2. Can only use each number once

Cannot do:
1. Use decimals.

Help!!!

6/(1-(5/7))

Thanks!!!

Would this work when it comes to the fact that you can not use any decimals, or would there be another trick to this...

Yes this works given the no decimals rule.

that rule refers to doing something like this 6.1/5.7

This solution satisfies all of the rules.
