Math answers with steps

He said (with the help of Turing's Thought): computers are mathematics in nature, and mathematics will face three problems. Are there clear answers to all mathematical problems in the world? If there is a definite answer, can we get the answer through the calculation of limited steps? Then, for those mathematical problems that may be calculated in limited calculation steps, can there be an imaginary machine that keeps moving, and finally when the machine stops, the mathematical problem is solved? When many students do math problems, they can't write the answers to the problems and have no ideas. After reading the answers, they have a sense of enlightenment and enlightenment. Some students can only write the answers directly after reading them, but I won't. will this be the case with many students. The more active, positive and effective you think in the process of doing questions, the less questions you need to do to achieve the same review effect. This is my summary of math review. Learning mathematics well does not need the strategy of sea of questions. It is not advisable to do a lot of questions without thinking, finish the questions, and finish the answers. When you find that the answer is incorrect, don't worry about the steps written in the answer. Because there may be many ways to solve the problem. You and the answer may be different, but they may all be correct. It's just that you made a careless mistake. If you follow the steps of the answer directly, you may neglect a way of thinking to solve the problem. Even if you think the same way as the answer, you will be more impressed by your own mistakes than by comparing the answers. We should standardize the steps of answering questions. In the college entrance examination, the steps to solve problems are very important. If the steps to solve the problem are not standardized or complete, points will be deducted. In the art examination culture class, we need to pay attention to the steps of checking the standard answers. Even if you have answered the question correctly, you should check what the standard answer is, so as to determine the content of the steps, and there should be no omission. Third, the answers are not clear. When students take the math test, they basically need to have steps to answer the applied questions, and they are also graded according to the steps, but some students will write a large number of steps, making people unable to find the key points. If Chinese reading thinking is applied to mathematical problems, there will only be a variety of answers, because Chinese answers are not certain. A mathematical problem is a problem solved according to one knowledge point and another knowledge point. The whole answer procedure is logical and the answer is standard and unique. 1、 The math problem is getting more and more difficult. Ten kilograms of salt, eat three kilograms and then eat two kilograms. What's the final answer?? When tutoring their children in homework, many parents are very confident, because they firmly believe that there will be no mistakes in the math problems they have done. What they didn't expect is that they got the wrong number of the teacher. For example, the following math problem shows that it is a grade one math problem. If you solve it with normal thinking, the answer must be five. Just like I have ten yuan, I spent three yuan the first time and two yuan the second time. Isn't it five yuan in total? In the view of many parents, this answer is definitely correct, but they did not expect that all students who wrote the answer 5 were judged wrong by the teacher. Although it is common for the teacher to correct the wrong question, it is necessary to let students understand what the correct answer is and build up their confidence in learning.
