“运算”往往被高三学生忽视。他们认为,解题的方法有了,步骤分析出来了,“计算”只要细心一些就行了,因此不愿动笔算到底。实际情况并不这样简单,翻开学生的作业、试卷,由运算而造成的错误是很多的。有时候最后一步的运算错误导致了客观性试题的分数全被扣去;有的题由于某一步的运算错误导致过程繁杂而影响了思考,有的题答案是算对了,但繁琐而不合理的运算浪费了大量的时间。
“Computing” is often ignored by senior students. They think that there is a solution to the problem, the steps are analyzed, and “calculation” is only a matter of being careful, so I do not want to finish the calculation. The actual situation is not so simple, open the homework, papers, the error caused by the operation is a lot. Sometimes the final step of the operation error led to the objective test scores were all deducted; some problems due to a certain step of the operation error caused the process complicated and influenced thinking, and some questions are right, but tedious and unreasonable The operation wastes a lot of time.
