It was a game that some1 wanted me 2 make 4 them. it took me bout an hour 2 make and well... i dont think its that good but... it was only simple. I hope it helps u with maths. There r quite a few errors at the m witch werent there b4 so im fixing them now.
Update1: It now has a timer which can be set bettween 10 and 60 seconds, and there now should be a higher range of numbers
