Somedays back, one of my co-workers popped this mathematical question for us to think about. It is fairly simple but complex for our minds. Anyway, here’s the question:-

5 . 5 . 5 . 5 . 5 = 24

Replace the . with any of the following operators: +, -, *, /. You may add brackets anywhere in-between the numbers or operators.

There are many solutions, have fun!
