两位数不进位不退位加减法竖式计算题
不退位减法、不进位加法、退位减法及进位加法习题
一年级不退位减法、加法,退位减法及进位加法习题一、知识要点。
(1)不退位减法:指两数相减时,被减数的个位数大于减数的个位不需要退位。
(2)不进位加法:指两数相加时,两数的个位数的和小于10时(<106+3=9,不需要进位。
(3)退位减法:指两数相减时,被减数的个位数小于减数的个位数,要用从被减数十位上往下退位,还要留下退位点“.”。
例:2。
6-7=19,6<7,6无法减7时,就需要从被减数十位上往下退位,从十位上借出一个“1”,代表是10。
10+6-7=9,这时个位就是9,十位借走一个“1”,十位还剩下一个“1”,所以结果就是19。
同时标好退位点“.”。
(4)进位加法:指两数相加时,两数的个位数的和等于或大于10时(≧10个位写下0,要往十位数进位,左下方标上小“1”,同时还要把这个“1”与十位上的数字相加,即2+1=3,所以结果就是30。
