One day your minimalist friend is visiting, and she presents you with the numbers 2, 3, 4 and 5, and the symbols = and +, and the following tantalizing challenge: It is possible to use each number and symbol once and only once and end up with a true equation; further, you cannot use any number or symbol not given. How can you do this?

2 + 5 = 3 + 4.

But have in mind that this is not an equation, because there is not a variable. It is an identity because it is alwasy true.
