"Math Training" is a digital learning machine that lets you get better at calculations with the exciting feeling of playing a game console!

The usage is very simple. On the first screen, you can freely choose which calculation you want to challenge today from "addition, subtraction, multiplication, and division." You can also combine multiple operations to create mixed problems!

Once you start, problems appear with a flash on a cool black display! It's smooth and easy to operate—just enter your answer and press "decide." If you can clear all the problems before your life reaches zero, you win big!

The movement is light and smooth. It's a new-sensation math tool that even small children can enjoy on their own with confidence!
