Math: Long Addition is an Android application developed by Epsilon Development, designed to teach users how to perform long addition. This fundamental concept of math is the basis of all arithmetic skills and the application is a smart way to learn it. The app offers two modes: learning and training. In learning mode, the app shows you how to do the addition step by step and explains each step in detail. You can select the numbers yourself or let the app randomly choose the addition to do. In training mode, you perform long addition step by step and the app detects mistakes, such as forgetting the carry, and gives you indications if needed.

The app offers several levels of math exercises, starting with simple numbers without carry, and progressing to more difficult exercises. This feature may also be helpful for dyscalculic individuals. Math: Long Addition computes a score based on time and mistakes during the long addition. Note that the app uses vocal synthesis to make comments during math exercises, and on some devices, it may prompt you to install upgrades for better diction quality.
