脱式计算即递等式计算,把计算过程完整写出来的运算,也就是脱离横式的计算。
在计算混合运算时,通常是一步计算一个算式(逐步计算,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。
(脱字念tuo)主要掌握的是记住要先算乘、除法,后算加、减法。在乘除法连续计算时中,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。
