四年级下册四则混合运算
四年级下册四则混合运算一、四则混合运算的概念。
1. 四则运算。
- 在数学中，四则运算是指加法、减法、乘法和除法这四种基本运算。
- 例如：2 + 3（加法），5-1（减法），4×3（乘法），12÷4（除法）。
2. 混合运算。
- 四则混合运算就是在一个算式里，包含了两种或两种以上的四则运算。
- 例如：2 + 3×4，这个算式里既有加法又有乘法。
二、四则混合运算的运算顺序。
1. 没有括号的情况。
- 先算乘除，后算加减。
- 例如：计算12 + 4×3÷2。
- 先算乘法：4×3 = 12。
- 再算除法：12÷2 = 6。
- 最后算加法：12+6 = 18。
2. 有括号的情况。
- 先算小括号里面的，再算中括号里面的（如果有），最后算括号外面的。
- 例如：计算[12+(4 - 2)×3]÷2。
- 先算小括号里的：4 - 2=2。
- 再算中括号里的乘法：2×3 = 6。
- 接着算中括号里的加法：12+6 = 18。
- 最后算括号外面的除法：18÷2 = 9。
三、四则混合运算的应用。
1. 简单的应用题。
- 例：学校图书馆有故事书120本，科技书比故事书的3倍少10本，科技书有多少本？- 分析：先算故事书的3倍，即120×3 = 360本，再减去10本，360-10 = 350本。
- 列式为：120×3 - 10=350（本）。
2. 较复杂的应用题。
- 例：小明去商店买文具，一支铅笔2元，一个笔记本5元。
他买了3支铅笔和2个笔记本，给了售货员20元，应找回多少钱？- 分析：先算出买铅笔的花费2×3 = 6元，再算出买笔记本的花费5×2 = 10元，总共花费6 + 10=16元，最后用20元减去总花费得到应找回的钱数。
- 列式为：20-(2×3 + 5×2)- 先算括号里的乘法：2×3 = 6，5×2 = 10。
四年级下册四则混合运算顺序
四年级下册四则混合运算顺序一、四则混合运算顺序加、减、乘、除四种运算统称四则混合运算。
在学习四则运算时，必须了解一下什么是中括号：①“[ ]”叫做中括号，又称方括号。
在四则混合运算中，如果使用小括号后还需再次改变运算顺序，就要加上中括号。
②一个算式里，既有小括号，又有中括号，要先算小括号里面的，再算中括号里面的，最后算中括号外面的。
注意：中括号一定要和小括号共同存在于一个算式里，而且中括号里面必须有小括号。
1.没有括号的四则混合运算顺序：（1）只有加、减法或只有乘、除法、按从左到右的顺序进行计算。
（2）既有加、减法，又有乘除法，要先算乘、除法，再算加、减法。
2.含有中括号的四则混合运算的运算顺序：先算小括号里面的，再算中括号里面的，再算中括号外面的。
注意：书写格式：在含有中括号的算式里，小括号里面的算完以后，中括号依然要保留。
中括号里面算完之后，才能去掉中括号。
二、常见题型：1.脱式计算（一定要注意书写的格式）。
2.讲清运算的顺序。
3.根据分步的算式或者图片写出综合算式。
4.利用倒推法找出算式中未知的数。
5.列式计算。
三、专项练习：知识点一：含有括号的四则混合运算的运算顺序1、计算96÷12＋4×2，说一说运算的顺序。
第一步：先算除法：96÷12＝8第二步：再算乘法：4×2＝8第三步：最后算加法：8＋8＝1696÷12＋4×2＝8＋8＝16不含括号的混合运算，先算乘、除法，再算加法。
2、在算式96÷12＋4×2中加上小括号，变成96÷（12＋4）×2，运算顺序变了吗？96÷（12＋4）×2＝96÷16×2＝6×2＝12加上小括号后，改变了运算顺序，结果也变了。
3、在算式96÷（12＋4）×2中加上括号“［］”，变成96÷[（12＋4）×2 ]，运算顺序变了吗？96÷[（12＋4）×2]＝96÷[16×2]＝96÷32＝3先算加法，再算乘法，最后算除法。
