● A calculation-specific app created by Wonder Lab, a team of educational app developers with 1 million users!
● Learn the ingenuity of calculations while having fun working through puzzle-type problems!
● Analyze 10 years of past questions from famous schools and extract 7 "techniques"!

◆What kind of teaching material is Ultimate Calculation?

This app focuses on how to devise calculations and solve them easily. By learning the essence of ingenuity, you will acquire applied skills and enjoy trial and error.
Calculation techniques are classified into seven "techniques" based on their properties. As you progress through the app, these techniques are designed to come naturally.
We have adopted a puzzle-like problem format so that you can feel the fun of inventing things as you work through them, rather than just doing simple tasks. The pleasure of learning the ``techniques of ingenuity'' and using those techniques to clear puzzles will keep you motivated.

◆Why is “calculation” important?

Reduce calculation errors and save time with ingenious techniques!
When solving math problems for junior high school entrance exams normally, it is necessary to calculate many times within a single question, so there are many cases where a small mistake can result in an incorrect answer. In order to avoid mistakes, it is important to make the calculations as simple as possible by being creative at the stage of solving the problem and making the calculations as simple as possible. By intentionally creating numbers that can be calculated mentally, calculation speed will dramatically increase, and the accuracy of calculations will also increase.

It is important to have the attitude of trying to innovate!
If you simply repeat learning, even if you can solve the problem, it will gradually become inapplicable and you will reach a dead end. If you have the attitude of always trying to innovate and acquire the basic techniques of ingenuity, you will be able to apply them in all situations.

Calculation ingenuity is the foundation of all learning!
Calculation itself is a skill that is essential not only for junior high school entrance exams, but also for later studies and even after entering the workforce. Even after you start using algebra and theorems in mathematics, whether or not you have the attitude to think creatively will make a big difference in your understanding. When faced with not only calculations but all kinds of unknown problems, whether or not you are willing to ``innovate'' will greatly influence your results.

◆Purpose of this teaching material
Calculation is the basis of arithmetic and mathematics, and is a fundamental field of learning that everyone will continue to be involved with throughout their lives. Rather than simply memorizing solutions and formulas, whether or not a child is willing to try and error in order to improve their calculations greatly influences the growth of their overall mathematical thinking.
``Ultimate Calculation'' is an app teaching material that was born from the pursuit of the fun of inventing ideas through trial and error, rather than just repeated practice or rote memorization of formulas. We hope that you will use this book not only as a teaching material to help you become good at calculations, but also as a teaching material that will help you feel the joy of inventing things, regardless of whether you are taking junior high school entrance exams or not.
