Given to me, by a friend:
How would you make 20, using two threes?
- You may use any basic operation. And others, such as square roots (the symbol), factorials, etc. Any operation is allowed.
- Just two threes, though. You can't raise a three to any digit other than three, etc.
Any out of the box, non-mathematical solutions are encouraged.
PS- Wow! That's an amazing number of responses! Quite a community, here.
EDIT: @CameronWhite and @Yly have provided, perhaps the most elegant answers. And basis your votes, I'm going ahead to mark @Cameron's answer as accepted. No issues, I hope. Although, I did think @KeyboardWielder's answer was rather crafty. And @dcyfj... Well, that would have taken some time. Awesome answer. This really isn't an edit, is this?
EDIT: Perhaps I should have specified the level of out-of-the boxness allowed. Forgive my mistake. This was, my first post, and I was surprised by the number of answers. Thanks for taking the time.
