三年级口算万以内加减法
三年级口算万以内加减法
以下是一些关于三年级万以内加减法口算的方法和练习:
一、口算方法
两位数加、减两位数
先把个位上的数相加减,再把十位上的数相加减。
例如:34 + 25,先算 4 + 5 = 9,再算 30 + 20 = 50,最后 50
+ 9 = 59。
几百几十加、减几百几十
把几百几十看成几个十,先算几十加几十或几十减几十,再算几百加几百或几百减几百。
例如:480 + 350,把 480 看成 48 个十,350 看成 35 个十,先算 48 + 35 = 83,所以 480 + 350 = 830。
整千、整百、整十数的加、减法
(1)整千数相加减,直接用千位上的数字相加减,后面添上三个 0。
例如:3000 + 2000 = 5000。
(2)整百数相加减,用百位上的数字相加减,后面添上两个
0。 例如:500 - 300 = 200。
(3)整十数相加减,用十位上的数字相加减,后面添上一个
0。
例如:70 - 40 = 30。
