Tips for checking math problems exam assignments .

The first is the speed of doing questions, when you are in junior high school, you can leave enough time to check, I think the number of questions you usually do is not enough, do more will naturally be faster, if you don't have time, no method can help you.

For the examination of math problems, the most direct way is to bring the answers into the question and check whether they match the meaning of the question. Recalculating is a waste of time, you can try to bring in the check after each question, if you find a problem, it is good to be able to solve it in time, and if you can't find the problem immediately, pass it first and finally have time to check it carefully (this kind of question that is not easy to find mistakes, you should start checking from the type of question you are good at, so as not to delay time.) ）

Be careful in the process of doing the questions to avoid mistakes.

* Hee-hee-hee ......I asked parents to check that the middle school exam is best done and then checked, because if you do a question and check it, it's easy to get to the point and not finish it, and the order of the checks is: start with what you think is the easiest, then the next easiest one, and so on, and the last one that you think is the hardest.

But a word of caution to be careful and fast.

If you're running out of time after writing the questions, you don't need to check the simple ones.

You should wear a watch during the high school entrance examination.

According to my experience in writing questions, I grasp the time to write the questions, and I am about 15 20 minutes before the end of the exam.

The squared difference formula is applied incorrectly.

19 plus one minus two, root number 19 plus two, root number nineteen minus two minus one, waiting for you 17

Both questions are correct, and the first question can be = at the end of the calculation
