把一个数分成若干等分,或求甲数是乙数的几倍,这种算法叫做除法。换句话说,除法是同一减数多次累减的简便计算方法。商业部门在求商品单价以及求毛利率、纯益率、费用率等相对数时就要用到除算。多年来,学珠算的人能够熟练掌握除算技术的比重很小。这主要由于:1.减算是除算的基础,减算不熟练所以学不好。2.传统算法要背口诀,在不常练常用的情况下易于遗忘或返生。3.除算用得不多,一般只占整个计算工作量的百分之五以下。
Divide a number into several equal parts, or find that the number is a multiple of B. This algorithm is called division. In other words, division is a simple calculation method of multiple reductions of the same subtraction. The commercial sector must use the calculation of the unit price of merchandise and the relative number of gross profit rate, net profit ratio, and expense rate. Over the years, people who learn abacus have been able to master a very small proportion of computing technology. This is mainly due to: 1. Subtraction is the basis for the calculation, and the subtraction is not skilled so it is not good. 2. The traditional algorithm is difficult to remember or return to life if it is not commonly used. 3. In addition to not much use, it usually only accounts for less than 5% of the total computational workload.
