Using 2, 3, 4, 5, +, and = exactly once each, find eqn for

[Messagehelp]

Can't figure this one out:

Using only 2, 3, 4, 5, "+" and "=", and using each only one time, create a true equation? 2+3=45. uses all the signs and numbers but it is not a true equation. You may not use any other signs or numbers.

I'm beginning to think it's a trick, but I'm probably just too dumb.

A couple of things, which may agree with your "trick" assessment...

First,
2 + 3 = 5 -- You didn't quite say I HAD to use them all. Sort of, but not explicitly.

Second,
Your example violates the premise of "ONLY". Creating '45' from '4' and '5' requires juxtaposition, which implies multiplication by 10. 4*10 + 5 = 40 + 5 = 45

How about
4+5=3²

I think you're right Gene. I wasn't even thinking of that...

Thanks.

Re: Need help making equation

Well, dismantle the + into - and - ; then: 2 - 3 = 4 - 5 :idea:
