5两、三位数乘一位数口算倍的认识笔算乘数中间或末尾有0的乘|法系统梳理估算【单击文字跳转链接】

61两、三位数乘一位数的口算整十、整百数乘一位数，先把整十、整百数看作一位数，按表内乘法算出积，再看乘数末尾一共有几个0，就在积的末尾添上几个0。整理复习整十、整百数乘一位数的口算方法：【点击返回】

7几十几乘一位数，将几十几分成几十和几，分别乘一位数，再把乘得的积相加。几十几乘一位数的口算方法：1两、三位数乘一位数的口算【点击返回】

8先把两、三位数看作与它接近的整十数或整百数，再与一位数相乘，估算出近似值。两、三位数乘一位数的估算方法：2两、三位数乘一位数的|估算【点击返回】

93倍的认识倍是两个数进行比较的一种关系。求一个数是另一个数的几倍，用除法计算，即倍数＝一个数÷另一个数；求一个数的几倍是多少，用乘法计算。【点击返回】

10365×41460221相同数位对齐，从个位乘起，用一位数依次去乘两、三位数每一位上的数，与哪一位相乘，积就写在哪一位的下面，哪一位上乘得的积满几十就向前一位进几。计算过程中，既要考虑后一位进上来的数，也要考虑向前一位所进的数。4两、三位数乘一位数的笔算【点击返回】

115乘数中间或末尾有0的乘法相同数位对齐，用一位数分别去乘三|位数每一位上的数。在与中间的0相乘时，如果有进位数，要加上进位数；如果没有进位数，要在这一位上写0占位。乘数中间有0的乘法的笔算方法：【点击返回】0和任何数相乘都等于0

125乘数中间或末尾有0的乘法先用一位数与多位数中0前面的数相乘，再看乘数末尾有几个0，就在积的末尾添写几个0。乘数末尾有0的乘法的笔算方法：【点击返回】
