This is a math quiz app where you compete to see how fast you can solve differential problems.
You can check how many differential calculation problems you solved within 30 seconds as a score.
It is also useful as a preparation for regular tests.
Junior high school students who are pre-learning, high school students who are currently studying mathematics, science college students who frequently use differential calculus, and working adults who are relearning high school mathematics would like to have fun studying differential calculus together.
