计算是我们在日常生活中应用最多的数学知识,可是随着年级的升高,小数、分数依次的出现,计算的步骤多了,数据繁了,正确率也大大地下降了。常听到同学们议论:“这些题我都会做,就是计算错了,真可惜!”真的很可惜,错误的题目老师、家长不用提醒,再做一次都能做对,可为什么会出错呢?现在一份数学试卷中,涉及计算的题目占85%以上。看来计算的正确率直接影响着我们的数学成绩。怎样 Computation is the most commonly used mathematical knowledge in our daily life. However, as the grade increases, decimals and fractions appear in turn, the calculation steps are more, the data is more complicated, and the accuracy is greatly reduced. I often hear the students talk about: “I will do these questions, that is calculated wrong, it is a pity!” Really regrettable, the wrong subject teachers, parents do not have to remind, do once again can be done, why would Error? Now a math test paper, accounting for more than 85% of the topics covered. It seems that the correct rate of calculation directly affects our math performance. how
