There are many reasons for this, one of which is the helplessness of not being able to do anything to solve a problem if you don’t know the formula for that problem. In other subjects, you can erase what you know to solve the problem even if you don’t know how to solve it, but math is very difficult to solve if you haven’t learned the formula beforehand. Another reason is that math has a lot of formulas, and there are many complex problems that require you to read the problem and think about how to solve it, rather than just adding variables to the problem and substituting formulas. These reasons cause students to give up on math and make it a hated subject. However, math can be fun when you know the formulas and solve complex problems. I hope that many students will find math fun and enjoy it.
