The only winning is not to play... right.
Wait, get it wrong? But why?! The challenge is to quickly pick out the answer without failing to follow the instructions, even if it seems counter-intuitive.

So if a problem is 2+5, pick anything but 7!

However, if the same numbers are being added, like 6+6, then it's 12.

It's simple as pillows. Add, subtract, multiply, and divide away!

So play it here:


Remember, 2+1 isn't three!
