Mathematicus

The idea of the app is ok but for primary school (aged 7) the idea of negative answers is a bit hard (7-14). This option should be able to be turned off.

Brilliant! I love this little App! Well worth the 59p I paid for it! Very easy to use & quick to run. Perfect for getting your brain cells working at the start of the day! 3 levels of difficulty, I'm starting on the easiest! Has a timer running when you're asked the question to get you working under pressure too! A must buy app if you're as good as me with your mental arithmetic!
