Take part in college students' math competition
What kind are you? If you are modeling, the most important thing is to exercise your ability to extract mathematical models according to specific conditions. Of course, your ability to calculate or use a calculator must be strong. The figures in the game are very incomplete and there are many decimals. If you didn't take part in the general competition, I recommend you to buy an example of PTN math competition on Amazon. Pute Male Mathematics Competition is an important reference for college students' mathematics competitions in China and other countries. The examples in the book can improve your cognitive level from the perspective of pure mathematics and mathematical logic.
