三位数乘两位数列竖式计算
三位数乘两位数列竖式计算在三位数乘以两位数的乘法运算中,我们可以使用竖式计算的方法,依次对每位进行计算,最后将结果相加得到最终的乘积。
下面我来详细解释一下具体的计算步骤。
假设我们要计算一个三位数abc乘以一个两位数de,那么计算步骤如下:1.首先将两位数的个位数与三位数的个位数相乘,得到一个个位数的部分积r1r1=c*e2.然后将两位数的十位数与三位数的个位数相乘,再乘以10,得到一个十位数的部分积r2r2=c*d*103.接下来将两位数的个位数与三位数的十位数相乘,再乘以10,得到一个十位数的部分积r3r3=b*e*104.再将两位数的十位数与三位数的十位数相乘,再乘以100,得到一个百位数的部分积r4r4=b*d*1005.最后将这四个部分积相加即可得到最终的乘积。
乘积=r1+r2+r3+r4以上就是三位数乘以两位数的竖式计算的步骤。
下面我给出一个具体的例子,来演示一下这个计算过程:假设我们要计算987乘以23首先计算个位数的部分积,r1=7*3=21然后计算十位数的部分积,r2=7*2*10=140。
接着计算十位数的部分积,r3=8*3*10=240。
最后计算百位数的部分积,r4=8*2*100=1600。
将这四个部分积相加,得到最终的乘积,乘积=21+140+240+1600=2001所以,987乘以23等于2001通过这个例子,我们可以看出,通过竖式计算,我们可以清晰地看到每一步的计算过程,从而减少出错的可能性。
但在实际计算中,我们不一定需要按照上述步骤依次计算,可以根据个人的计算习惯和方便性来灵活选择计算顺序。
关键是要保证每一个部分的计算准确无误。

三位数乘两位数的乘法法则
1、先用两位数个位上的数去乘三位数的每一 位,得数的末位和两位数的个位对齐。
2、再用两位数十位上的数去乘三位数的每一 位,得数的末位和两位数的十位对齐。
3、然后把两次乘得的数加起来。ຫໍສະໝຸດ 作业课本47页做一做。
