二年级数学100以内加减法速算方法带练习
100以内加减法速算方法方法 1. 两位数加两位数的进位加法：口诀：加9要减1，加8要减2，加7要减3，加6要减4，加5要减5，加4要减6，加3要减7，加2要减8，加1要减9。
（注：口决中的加几都是说个位上的数）例：26+38=64 解:加8要减2，谁减2？26上的6减2。
38里十位上的3要进4。
（注：后一个两位数上的十位怎么进位，是1我进2，是2我进3，是3我进4，依次类推。
那朝什么地方进位呢，进在第二个两位数上十位上。
如本次是3我进4，就是这两个两位数里的2+4=6。
）这里的26+38=64就是6-2=4写在个位上，是3进4加2就等于6写在十位上。
再如42+29=71。
就用加9要减1这句口决，2-1=1，把1写在个位上，是2我进3，4+3=7，把7写在十位上即得71。
两位数加两位数不进位的加法，就直接写得数就行，如25+34=59，个位加个位写在等号后的个位上5+4=9，十位加十位写在十位上即可2+3=5，即59。
不必列竖式计算。
本办法学会了百试百灵，比计算器还快。
方法 2.两位数减两位数的退位减法。
口决: 减9要加1，减8要加2，减7要加3，减6要加4，减5要加5，减4要加6，减3要加7，减2要加8，减1要加9。
（注：口决中的减几都是说减个位上的数）。
例：73-46=27，解：减6要加4，谁加4？3加4等于7写在个位上，减数的十位是4我退5，谁退5？7退5，即27。
（注：如何退位？减数的十位是1你退2，是2你退3，是3你退4，依次类推，但必须是个位减个位不够减的情况才能这样退，够减就直接个位减个位，十位减十位直接定出得数即可。
）以上两种方法是利用了一年级教材中的凑十法演变而来的。
它们的口决大体一致，只需记住了其中的一种，另一种方法即可融会贯通。
