Big Addition

Improve your long addition speed and accuracy on the go!

Big Addition can help you improve your problem solving speed and accuracy for multi digit addition problems.

If you need a refresher, there is a step-by-step problem solver in the practice area that can read-out the solution to you a step at a time. (Text-to-speech support required.)

Larger, more difficult, problems are unlocked by solving smaller/easier problems.

You can analyze your problem areas with both numerical and color-coded display of your results.

Stay motivated by setting and beating your fastest times.

Find your best rhythm by turning off/on any combination of verbal, sound, and vibration feedback.
