Without a good teacher, you have to cultivate yourself. Every time you encounter a problem with numbers, you should think about whether your teacher can solve such knowledge in the content. Connect mathematics with life.

See a building, for example, think of a * * *, how many floors, how many meters each floor, a * * *, how many meters.

When you go to a restaurant to eat, think about how much each dish costs, how much money you finally paid, how much taxes your parents paid, and how much money the boss can earn. Don't forget to calculate the coffee table fee.

Over time, if you don't have obsessive-compulsive disorder, you should have feelings about mathematics.
