用字母表示为()。

4、在没有括号的算式里,有乘、除法和加、减法,要先算()再算()。

被减数等于减数,差是()5、在一个没有括号的算式里,既有乘、除法,又有加、减法,要先算()法,后算()法。

6、三个数相乘,先把()相乘,再和()相乘;或者先把()相乘,再和()相乘,它们的结果不变,这叫做()。

用字母表示为()。

7、计算64×26后,可以交换两个数的位置验算,是用了()律。

小学数学四年级四则混合运算及运算法则知识点整理附练习题文章目录四则运算(一)加法运算定律:1、两个加数交换位置,和不变,这叫做加法交换律。

字母公式:a+b=b+a2、先把前两个数相加,或者先把后两个数相加,和不变,这叫做加法结合律。

字母公式:(a+b) +c=a+(b+c)(二)乘法运算定律:1、交换两个因数的位置,积不变,这叫做乘法交换律。

字母公式:a×b=b×a2、先乘前两个数,或者先乘后两个数,积不变,这叫做乘法结合律。

字母公式:(a×b)×c=a×(b×c)3、两个数的和与一个数相乘,可以先把它们与这个数分别相乘,再相加,这叫做乘法分配律。

用字母公式:(a+b)×c=a×c+b×c或a×(b+c) =a×b+a×c拓展:(a-b)×c=a×c-b×c或a×(b-c) =a×b-a×c(三)减法简便运算:1、一个数连续减去两个数,可以用这个数减去这两个数的和。

用字母表示:a-b-c=a-(b+c)2、一个数连续减去两个数,可以用这个数先减去后一个数再减去前一个数。

用字母表示:a-b-c=a—c-b(四)除法简便运算:1、一个数连续除以两个数,可以用这个数除以这两个数的积。

用字母表示:a÷b÷c=a÷(b×c)2、一个数连续除以两个数,可以用这个数先除以后一个数再除以前一个数。

用字母表示:a÷b÷c=a÷c÷b小学四年级数学“四则运算”知识点详解知识点一:四则运算的概念和运算顺序1、加法、减法、乘法和除法统称四则运算。

2、在没有括号的算式里,如果只有加、减法或者只有乘、除法,都要从左往右按顺序计算。

3、在没有括号的算式里,既有乘、除法又有加、减法的,要先算乘除法,再算加减法。

小学四年级课后练习四则混合运算练习及答案20题小学四年级课后练习 - 四则混合运算练习及答案20题一、计算题:1. (25 + 43) × 2 ÷ (16 - 8) =2. 36 × (5 - 3) + 24 ÷ 8 =3. 78 ÷ 3 + 15 - (16 × 2) =4. 72 ÷ 8 - 9 × (4 - 3) =5. (40 × 2 - 30) ÷ 4 + 5 =6. (84 - 36) ÷ 6 + 9 =7. 68 ÷ (4 + 2) × 3 - 5 =8. (42 - 18) ÷ 4 + 3 × 2 =9. 62 ÷ 2 + 4 - (27 + 5) =10. (9 + 7) × 4 - 12 ÷ 6 =二、解答题:11. 小明有24本绘本,他想平均分给他的4个好朋友,每个朋友分到几本?12. 一个长方形花坛的长是8米,宽是3米,求它的面积是多少平方米?13. 爸爸给小明买了一盒蛋糕,一盒有6个,小明吃了2个。

小明把剩下的蛋糕分给了他的3个邻居,每个邻居分到几个?14. 在一个果园里,小红采摘了18个苹果,小明采摘了比小红多6个苹果,他们一共采摘了多少个苹果?15. 阿姨给小强买了4条裤子,每条裤子的价格是27元,小强给了阿姨100元,阿姨要找给小强多少钱?三、答案:1. (25 + 43) × 2 ÷ (16 - 8) = 1362. 36 × (5 - 3) + 24 ÷ 8 = 843. 78 ÷ 3 + 15 - (16 × 2) = 154. 72 ÷ 8 - 9 × (4 - 3) = -15. (40 × 2 - 30) ÷ 4 + 5 = 156. (84 - 36) ÷ 6 + 9 = 187. 68 ÷ (4 + 2) × 3 - 5 = 138. (42 - 18) ÷ 4 + 3 × 2 = 139. 62 ÷ 2 + 4 - (27 + 5) = 510. (9 + 7) × 4 - 12 ÷ 6 = 5211. 每个朋友分到6本绘本。

125×88 390÷[13×(20-14)] 735×[(700-400)]÷25
三、解决问题:
(1)甲、乙两列火车同时从相距700千米的两地相向而行,甲列车每小时行80千米,乙列车每小时行60千米,几小时两列火车相遇?
(2)甲、乙两车同时从相距480千米的两地相对而行,甲车每小时行45千米,乙车每小时行35千米,几小时后两车相遇?
(3)A、B两地相距3400米,甲、乙两人同时从两地相对而行,甲每分钟走82米,乙每分钟走83米,已经行了20分钟,他们相遇了吗?
(4)甲、乙两列汽车同时从两地出发,相向而行。

已知甲车每小时行45千米,乙车每小时行32千米,经过4小时后还相距2千米,相遇求甲乙两地相距多少千米?
(5)小明、小丽、小芳同时跳绳,跳了3分钟,小明每分钟跳89个,小丽每分钟跳92个,小芳每分钟跳91个,他们一共跳了多少个?。
