    脱式计算,即递等式计算,把计算过程完整写出来的运算,也就是脱离竖式的计算.在计算混合运滚悔算时,通常是一步计算一个算式(逐大哗正步计算,等号不能写在原式上),要写出每一步的过程.一般来说,等号要往前,不与第一行对齐.也就是离开原式计算.举例250÷50+12×4=5+48=53如何脱式计算?

    如何脱式计算?主要掌握的是记住要先算乘、除法,后算加、减法.在乘除法连继计算时中,要按从左往右的顺序依次计算.遇到括号,要首先计算括号内部.在脱式过程中要按运算顺序划出运算顺序线,还要做到“三核对”,一要核对从书上把题抄到作业本上数字、符号是否抄对.二要核对从横式抄到草稿竖式的数字、符号是否抄对.三要核对把草稿竖式上的得数,抄到横式上是否抄对,小数点是否点对地方,有无遗漏.

    =1064

    2、(250÷50)+(12×4)

    =5+48

    =53

    在脱式过程中要按运算顺序划出运算顺序线,还要做到“三核对”,

    一要核对从书改悉上把题抄到作业本上数字、符号是否抄对;

    二要核对从横式抄到草稿竖式的数字、符号是否抄对;

    三要核对把草稿竖式上的得数,抄到横式上是否抄对,小数点是否点对地方,有无遗漏。

    扩展资料

    在四则运算中,加法和减法叫做第一级运算,乘法和除法叫做第二级运算。含有两种或两种以上的运算的算式,通常称为混合运算。加、减、乘、除的混合运算也叫做四则混合运算。在四则混合运算中,规定的计算先后次序,称为运算顺序。数学上规定的四则运算顺序如下:

    (1)同级运算在一个算式中,如果只含有同级运算,应当按照从左到右岁慧的次序进行运算。这就是说,只含有加减法,或者只含有乘除法的混合运算,它们的运算顺序是从左到右依次计算。

    (2)一至二级运核雀乎算

    在一个算式中,如果既含有第一级运算又含有第二级运算,那么,应先算第二级运算,后算第一级运算。即"先算乘法和除法,后算加法和减法",简称"先乘除,后加减"。

    (8)(26-19)×6

    (9)64÷(24-16)

    (10)36+48-25]

    简便计算方法:

    1、在同级运算兆租中,可以任意交换数字的者猜旦位置,但要连着前面的符号一起交换。(加法或乘法交换律)

    2 、在同级运算中,加号或乘号后面可以直接添括号,去括号。减号、除号后面添括号,去括号,括号里面的要变号。(加法或乘法结合律)

    3、凑一法,凑十法,凑百法,凑千法:“前面凑九,末尾凑十”。

    必记:25找4凑100,125找8凑1000。 (凑整思想)
