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。

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。
4、算式有括号，要先算括号里面的，再算括号外面的；大、中、小括号的计算顺序为小→中→大。
括号里面的计算顺序遵循以上1、2、3条的计算顺序。
知识点二：0的运算1、0不能做除数；字母表示：无，a÷0是错误的表达2、一个数加上0还得原数；字母表示：a＋0 = a3、一个数减去0还得原数；字母表示：a－0 = a4、一个数减去它本身，差是0；字母表示：a－a =05、一个数和0相乘，仍得0；字母表示：a×0 =06、0除以任何非0的数，还得0；字母表示：0÷a =0(a≠0)知识点三：运算定律1、加法交换律：在两个数的加法运算中，交换两个加数的位置，和不变。
