Conundra Math: a brain training number game for iPhone and iPad

I'm just using the free version, so no access to the more difficult levels. Even so the highest available level is fun to use and great for developing mental arithmetic.

When I’m tired instead of scrolling through things in the Internet I enjoy doing this much to my surprise. I’d thoroughly recommend it.

Its crazy stuff, l am enjoying every bit.

This isn’t maths, doesn’t apply mathmatics rules and needs to have brackets for the purist

A once-a-day(min.) brain boost.

Works well, nice and simple good job

Perfect for keeping the old grey matter sharp!

A great way of keeping the old grey matter young !

Enjoy playing. Some hard to make your brain work, some easy to avoid straining it.

Math is not my best subject. I was hoping to improve my skills. I don't find this helpful. How do I put in brackets? It doesn't mention that anywhere. The countdown score is so large that it's off-putting, and the answer doesn't stay long enough for me to be able to think about where I went wrong. 1/10
