Using each of the digits 2, 3, 4 and 5 only ONCE, plus one "+" sign, and one "=" sign, can you write a correct equation?
My answer is:
4 + 5 = 3²
My belief is you can only use the symbols provided. Especially as 4/2 (for example) is 4 divided by 2. Whereas though the 2 in my answer is 'squared' it requires no external symbol.
Thanks federico for this quick and easy puzzle
