* About "a master of the proof"
This application is the application that can master a problem of the proof of the second grade at a junior high school smoothly.
* Characteristic
● You can use it to the "proof" who wants to master basics of the second grade at a junior high school textbook level.
● Because it is changed at random, I can practice the problem enough.
● I can practice every pattern progressively.
● Because the way of thinking is illustrated, I can easily confirm it where it is different.
