Great app for kids This app is just what my 3rd grader and I had been looking for. Fully customizable to work on just the math facts he wants. Just be sure to hit the enter key in the settings before pressing "done", to lock in the changes. Almost as good as the iPhone's "math drills" by Instant Interactive.
Added ability to move app to SD card and run there.
All Mathematics Formulas - must have app for your smartphone and tablet.
Does numerous calculations not available or not easily done on most calculators.
