There is always a hint in my heart every time I take the exam. I know that the calculation is going to make mistakes. When I get a question, I will be confused even if I see a very simple exponential operation. It's easy to make mistakes in solving equations, and the plus and minus signs are often written wrong, Decimal division takes half a day. Am I useless? Alas, I'm not afraid of doing problems. I just think I'm too stupid. Sometimes I really think I'm not the material of mathematics. Alas, I'm really helpless and desperate. So I'd like to ask you for some specific methods, such as some accurate calculation skills. Thank you very much! There are physical and chemical quite a headache ah, the exam always want to come over!
