Question

Another brain exercise :DDD

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?

Answer 1

did you leave out a symbol?

Answer 2

Am I right?

Answer 3

you used + twice

Answer 4

Darn..... I was so excited

Answer 5

e.g. 4 - 2 + 3 = 5

Answer 6

\[how about \ 3^{2}=4+5\]

Answer 7

OK, but if you have to specify + and -, don't see how you don't have to specify exponentiation.
