《经济生活》计算题一直是学生在学习过程中的难点,也是高考中的容易失分点。笔者在不断总结教学经验和学生反馈意见的基础上,归纳出一套四则运算方法,比较适用于教学且易于学生掌握。事实上,《经济生活》中的计算题实质是确定两个符号的问题,我们可以把《经济生活》计算题的计算,概括为以下公式模板:A_(1_X%)=B,A是已知量,B是我们要求出的量,而求出这一量,我们必须确定出公式模板中的横线部分的符号。
The calculation of “economic life” has always been a difficult point in the learning process for students and also an easy point to lose in college entrance examination. Based on the continuous summarization of teaching experience and feedback from students, the author summed up a set of four computing methods, which are more suitable for teaching and easy for students to master. In fact, the calculation questions in “economic life” essentially determine the two-symbol question. We can summarize the calculation of “economic life” calculation questions as follows: A_ (1_X%) = B, A is the known Quantity, B is the quantity we ask, and to find this quantity, we have to determine the sign of the horizontal line in the formula template.
