RAY: This was sent in recently by Jihad Adwan and it's a simple mathematical puzzler though if you tried you could go way off track with it.
I'm going to give you the numbers, 2, 3, 4, and 5. Now you can use each number only once in any kind of mathematical operation you see fit. And, whatever operation you use, you can also use that operation only once.
And when you do whatever you do with these operations -- addition, subtraction, parentheses, square root, etc--- you must end up with the number 26.
I'll give you an example. You could have 5 times 4 over 2, in parentheses, plus 3. Now that would be wrong because that equals 13, but you get the idea.
Think you know? Drop Ray a note!
