1. Learning mathematics is both hard and interesting. There are always several peaks to climb in life, so define one of them as mathematics, because it is worth doing.

2. Mathematics is a subject with large amount of calculation and strong logical ability! Do more questions, if you can't, try to think for yourself first, and then ask others when you really don't understand, so learning math may be much easier!

3. Make your brain more flexible, clearer and more organized.

First, be careful in the future, never be careful. Second, do more and practice more in the future. As the saying goes, "recite 300 Tang poems, even if you can't write." Third, use time! Hurry up! But, quick, easy to make mistakes! How can it be fast? There is only one way: practice more!
