Very useful

This is a nice little app for practicing basic mathematical operations and tracking ones progress.

The ability to track which operations/numbers need improvement is a great feature, as is the ability to pick exactly which operations/numbers to practice!

It has only two small flaws. Firstly, the apps sounds play even when turned off (they also override the ipads volume control). Secondly, the settings allow only up to the 12x12 multiplication table (up to 20x20 would be a nice feature).

Nevertheless, I am very pleased with this app.
