In Japan, mental arithmetic is a type of calculation that uses numbers to perform logical operations such as addition, subtraction, multiplication, and division. It is a method of learning mathematics that can be learned by adults and used to improve calculation skills. In the past, mental arithmetic was used to be a useful method for learning mathematics and it was studied by many people.

In the modern world, however, mental arithmetic is rarely used in school or daily life. As a result, most people have never had any experience with it. Even if they have a relatively good mathematical ability, they have never been taught how to calculate or reason mathematically. In fact, most of the time, they do not even know how to use a calculator. This means that they cannot solve mathematical problems in their head. They are also not good at estimating numbers.

On the other hand, the game "Chick Math" will help people learn mental arithmetic and improve their calculation and estimation skills. You can play this game with your friends or family and it is suitable for all ages. The game consists of four modes: adding, calculating, multiplying, and dividing.

In the first mode, you will be given a number and you have to calculate the sum of the numbers 1 through 5. The more numbers you add, the more difficult the problem is. You will not be given any hints. If you add the numbers correctly, you will be given a bonus. If your answer is correct, the time limit will recover slightly and the level of the problem will rise little by little. The more score you solve, the more difficult the problems will increase.
