♣ Of all subjects, mathematics is a subject in which you must be sure to deal with incorrect answers, especially for wrong problems.

♣ Usually, the problem is directly transferred or cut out to make an incorrect answer note. For candidates, time is more important than gold, so don't spend time on useless work.

♣ If you use the "Math incorrect answer note" application, you can easily take a picture to make an incorrect answer note. Try to solve the wrong questions made in the form of a test paper again so that you will not be wrong again!

▶At the time of development, I was a high school student (currently a university student!) I am studying mathematics, but he recommended that making an incorrect answer note is important for mathematics around me. But when I tried to do it, it seemed like a waste of time to have to rewrite the problem or cut and paste it myself. I was looking for an incorrect answer note app in the Play Store, but I didn't find an app that I liked. So I decided to make it once, and finally I finished it and released it like this.
