Some people,
1, can do the problem, why is it wrong? Just because hands and brains don't cooperate; This is right, but it is wrong.
The simple question is what can go wrong. Just because the eyes and brain don't cooperate; Wrong, right, wrong question.
These two phenomena are common among primary and secondary school students.
To get rid of this bad habit, we should first read more, recite more and write more. These three are carried out simultaneously. If a topic is, it is best to pronounce it while writing, so that the brain will know what it is. Get the result. After forming this habit. Just don't make any noise when you read it at the end. As long as it doesn't affect others
The following methods are recommended:
1, we should develop the good habit of careful calculation at ordinary times, and strive to greatly improve the accuracy of the first calculation through a period of training. Because once a mistake is made, it often takes more time to check and correct it than to do a new problem.
If possible, set aside some time to train the accuracy of the calculation. Give yourself a question, no problem, but the calculation must be very complicated. The calculation is not limited, but it is required to do it right once. I received this kind of training in primary school, and the calculation accuracy has been very high since then (obviously higher than the average level of friends around me)
2. Count the error-prone steps in your previous practice. If you encounter such a place in the future, slow down and deal with it carefully. Calculate this step twice before proceeding to the next step.
3, check, change a method. For example, the problem of solving an equation can be directly substituted into the equation to see if it holds. If the equation in the third step is wrong, the equation in the fourth step is right, which proves that the calculation in the fourth step is wrong. Some problems can be considered in special circumstances when checking. If there is a problem in a certain step under special circumstances, then there must be an error in this step or before. For example, an ordinary triangle is given in the geometry question, which can be regarded as a right triangle or an isosceles triangle when checking. If the above methods are not easy to use, do other questions first, then redo this question after shielding the answer, and then compare the different places after finishing. Zhongzhong
