求一个数的若干倍是多少用乘法计算。换句话说,乘算是一个数多次相加的简便算法。商业部门经常用数量和单价相乘求出销售额和库存额。在商业经济核算中乘算约占1/4。乘算的运算过程是把一个个部分积拨入相应的档位完成的,所以它的基础是加算。要使乘算技能达到高水平,必须做到以下几点:1.非常熟练的加算技能。2.大九九口诀能在脑中闪现。3.避免使用顶珠、底珠和悬珠。4.尽可能地配合心算。5.掌握适用的定位。这些将在阐述算法时逐项说明。
Find a number of times how much is calculated by multiplication. In other words, multiplication is a simple algorithm for adding numbers multiple times. The business unit often multiplies the quantity and the unit price to find the sales amount and the stock amount. In business accounting calculations account for about 1/4. The operation of multiplication is to allocate one part to the corresponding gear to complete, so it is based on the addition. To make the multiplication skills to achieve a high level, we must do the following: 1. Very skilled plus arithmetic skills. 2. Nine nine tactics flash in the brain. 3. Avoid using top beads, beads and beads hanging. As much as possible with the heart. 5 master the applicable positioning. These will be explained item by item when explaining the algorithm.
