人教版四年级数学下册典型例题系列之第六单元小数的加法和减法计算篇(含答案)
人教版四年级数学下册典型例题系列之第六单元小数的加法和减法计算篇（原卷版）编者的话：《2023-2024学年四年级数学下册典型例题系列》是基于教材知识点和常年考点考题总结与编辑而成的，该系列主要包含典型例题和专项练习两大部分。
典型例题部分是按照单元顺序进行编辑，主要分为计算和应用两大部分，其优点在于考题典型，考点丰富，变式多样。
专项练习部分是从常考题和期末真题中选取对应练习，其优点在于选题经典，题型多样，题量适中。
本专题是第六单元小数的加法和减法计算篇。
本部分内容考察小数的加减法计算，题型和考点较多，建议作为本章核心内容进行讲解，一共划分为十四个考点，欢迎使用。
【考点一】小数的加法计算及验算。
【方法点拨】1.位数相同的小数加法的笔算方法：（1）相同数位对齐，也就是小数点对齐。
（2）从末位算起，计算加法时，哪一位相加满十，要向前一位进1。
（3）得数的小数点要与竖式中横线上的小数点对齐。
2.位数不同时，先在位数小的小数后添上“O”变成位数相同，然后再根据位数相同的小数加法计算。
【典型例题】列竖式，并验算。
(1)5.4+2.8= (2)5.42+2.6= (3)7+5.88=【对应练习1】坚式计算：1.44＋17.6。
【对应练习2】用竖式计算。
61.6＋31.9= 24.08＋4.33=【对应练习3】用竖式计算下面各题并验算。
3.52＋9.6＝4.51＋2.78＝【考点二】小数的减法计算及验算。
【方法点拨】1.位数相同的小数减法的笔算方法：（1）相同数位对齐，也就是小数点对齐。
（2）哪一位不够减，就从前一位借1当10，在本位上加10再减。
（3）得数的小数点要与竖式中横线上的小数点对齐。
2.位数不同时，先在位数小的小数后添上“O”变成位数相同，然后再根据位数相同的小数减法计算。
【典型例题】列竖式，并验算。
(1)5.78-1.46= (2)6.89-2.3= (3)7-1.87=【对应练习1】14.4-3.5= 32.05-0.75=【对应练习2】用竖式计算。
