F. 二年级脱式计算题
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。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。
