About

かけざんアプリ

Features
Read full description

The important thing about learning by memorization is balancing input and output. With this app, you can master multiplication tables quickly by alternating between input and output. Not only kids who are somewhat familiar with multiplication tables, but kids who are completely new to them can learn naturally and enjoy it like a game. As soon as a mistake is made in a question, the correct answer is spoken aloud to help memorization. In this way, weak spots in memory can be rectified quickly. Questions answered wrongly will be repeatedly given until correct and reappear after a while. With this double-training system, multiplication is ingrained in both short-term memory and long-term memory. Unnecessary decorations are left out as much as possible so studying is the main focus and concentration is improved. We hope this app will be useful to many people.
