I am good at math, which is rare.

But only in graphics. It's over as soon as it's done ~

Anyway, the way to ensure my high score for so many years is to check it after I finish it quickly.

This is a reverse check to introduce numbers. ...

It is easy to find that it is wrong.

Because after completing a question, you have to follow the check, only checking whether the numbers are right or not, and you can't check the method problems at all, so it is scientific to bring the results into the most original formula check.
