Numbers Puzzle app for iPhone and iPad

If you like math you will love this game. The basic math operations (addition, substraction, multiplication and division) look easy but can be challenging when you have a result to get and the time limit chasing you!
Rules
- The goal of the game is to get the number you see in the top of the screen in less than the seconds left shown (also on the top of the screen)
- If you tap on a number, than number adds to your total (but it doesnt show anywhere, so you need to remember!)
- If you click on an operator ( -, *, / ) that current total is substracted, multiplied or divided by the value coming after.
(please note that a division by zero yields zero in this game, not infinity or undefined as you might expect)
