Math Workout

Most of the usual Android download sites have a comment or two saying that people are cheating on Math Workout Pro and that there's no way that someone can finish the World Challenge in 45 seconds. My username on the game server is 'hamster'. I don't get under 45 seconds very often but I just thought I'd upload this to show that it can be done in this sort of time. Granted the questions aren't degree level maths but I find it does help keep my mental arithmetic sharp. If you like it, support the developers at http://www.mathsworkout.net
