Math: Long Multiplication is an educational application developed by Epsilon Development for Android devices. This free app teaches you the fundamental concept of long multiplication and helps you consolidate your multiplication tables. The app offers two modes: learning and training.

In learning mode, the application shows you how to do long multiplication step by step and explains each step of the math exercise in detail. You can either choose the numbers or let the app randomly generate the long multiplication problem. On the other hand, in training mode, you do the long multiplication step by step by yourself and train your multiplication tables. The app detects your mistakes and provides appropriate indications throughout the exercise.

The app offers several levels for math exercises, starting from easy levels that include simple numbers without carry to more difficult exercises that involve carry. It calculates your score based on time and mistakes during the long multiplication, which motivates you to train and track your progress. The app also uses vocal synthesis to comment on the long multiplication during math exercises. However, on some devices, it may prompt you to install upgrades for better diction quality.
