Hello, I am a student of Harbin No.9 Middle School. Mathematics for senior high school entrance examination 1 16. In fact, mathematics in the senior high school entrance examination is not difficult, nor is it very basic. I don't know what level you are, just give me a rough idea. If it's 26, it's almost enough to practice the application problem of 10 type. The key is to fully understand the known conditions. When answering questions, you can draw them with a pencil and bring them back to the equation. Simple plane geometry, usually do more, remember some conclusions and understand that the proof process will be helpful to this problem. Be careful with this key, this score is free, we can't help it, I hope it will help you.
