The application will teach you how to do a long multiplication. The application is smart: it tries to understand your mistakes and give you appropriate indications.

The long multiplication is a fundamental concept of math. Long multiplication is one of the basis of all the skills developed in arithmetics and in math in general. And it makes you learn and consolidate multiplication tables.

The application proposes two modes: training and learning.

In learning mode, the application shows you how to do the long multiplication step by step. Each step of the math exercise is explained and detailed. You can choose the numbers, or let the application randomly choose the long multiplication to do.

In training mode, you do the long multiplication step by step by yourself, and you train multiplication table by the way. The application detects the mistakes, such as forgetting the carry. It gives you indications if you need all along math exercises.

Several levels are possible for math exercises. The easy level proposes simple numbers, without carry : you just use multiplication tables. The following levels proposes more and more difficult exercises, in particular using the carry.

The application computes a score from time and mistakes during the long multiplication. This gives you motivation to train and let you see the progression in the long multiplication.

Practicing math is important !

Note: The application uses vocal synthesis (it speaks) to comment the long multiplication during math exercises. On some devices, it will propose to you to install upgrades of vocal synthesis if you want to get better diction quality.
