Math brush 53 has always been wrong, and the hit rate is10 ... After reading the answer, I understand 70% to 80%, but I still feel that there is nothing to gain, so I want to do the problem and learn it well. No, don't look at the answer first. Deduct a question when you have time. If you don't think so, then deduct it to the deduction meeting. Moreover, the question on May 3rd is basic and difficult. If you haven't laid a good foundation, do, understand and recite it on the basis. Science needs rational thinking. You must understand a problem and then consolidate your practice every day. If you say you. Analyze everything he said clearly, then do it again by yourself instead of memorizing the answers, then practice this problem all week, write it once a day, and then deepen this type of problem. When you do the questions, look at the stem, cross out the unimportant ones, find out the important ones, analyze what you will ask and watch the questions do. That's how I got here, and so was my sister.

Hope to adopt, thank you.
