本册教材中的两步计算应用题可分为三组:第一组是含有三个已知条件的两步计算应用题。第二组从结构上看,只给出两个已知条件;从数量关系上看,是已知两数相差多少(或倍数关系)与其中一个数,求两数的和或差。第三组是已知两数之和与其中一个数,求两数相差多少或倍数关系。第三组题的问题虽然与第

Two-step computational questions in this textbook can be divided into three groups: The first is a two-step computational problem with three known conditions. The second group from the structural point of view, only given two known conditions; from the quantitative relationship between the known number is the difference between the number (or multiple relationship) and one of the number, find the sum of the two or poor. The third group is known the sum of two numbers and one of the numbers, find the difference between the number of two or multiple relationship. The third group of questions though with the first
