How to do math problems quickly and accurately?
First of all, you have to read this book, understand it and understand it. I am from the Department of Applied Mathematics of Dalian University of Technology. One of our professors (the most advanced mathematician in topology in China) said that if you can't do the problem, you should read the conditions again first, and then you can't, which means you don't understand the book. Put down the topic and finish reading the book.

Secondly, we should do more questions, choose a good problem set and find out the questions, such as using reduction to absurdity or mathematical induction. After that, we should control the time. For example, it takes about 30 to 40 minutes to fill in the blanks in the math problem of the college entrance examination.

Finally, you should have mathematical thinking when doing the problem. Mathematics includes mathematical thought and mathematical logic. For example, when doing multiple-choice questions, the method of asking questions is a quick and accurate method, which can be described as "tried and tested", as well as the exclusion method and so on. When you do a big problem, you should look at the problem clearly. In general, one condition is public testing. You have to understand what this condition is for and what it does. Diversified your thinking, don't mind a blank, stagnant situation.

People's IQ is similar, you have the ability to learn mathematics, and you believe that you will be faster and more accurate. The idea of an old man is for reference only, and our method is not easy for everyone.
