怎样解应用题?小学学过两种解法:一种是列算式解,另一种是列方程解.通常,把前一种解法叫做算术解法;把后一种叫做代数解法.这两种解法有什么区别呢? 先看一个例子:甲、乙两人各要加工某种零件240个,甲每小时加工30个,在相同时间里,当甲完成任务时,乙还有48个零件没有加工好.问乙每小时加工零件多少个? How to solve the problem? Primary school learned two kinds of solutions: one is a solution, the other is a solution of the equation. Usually, the former solution is called an arithmetic solution; the latter is called an algebraic solution. These two solutions What’s the difference? Let’s look at an example: Let’s look at two examples: one for each of A and B, and one for 240. One will process 30 per hour. At the same time, when A completes the task, B has 48 parts that are not processed. OK. Q. How many parts per hour are machined?
