普通高中《数学课程标准》中有这样的一句话“熟练掌握一些基本技能,对学好数学是非常重要的.在高中数学课程教学中,要重视运算、作图、推理、处理数据以及科学计算器的使用等基本技能训练.但应注意避免过于繁杂的技巧性过强的运算.” The common high school “mathematics curriculum standards” has such a sentence “Mastering some basic skills, is very important for learning mathematics. In high school mathematics curriculum teaching, we must pay attention to computing, mapping, reasoning, data processing and scientific computing Basic skills training such as the use of the device. However, care should be taken to avoid overly complicated and technically intensive operations.”
