后算加,等号不能写在原式上),通常是一步计算一个算式(逐步计算。三要核对把草稿竖式上的得数。遇到括号、符号是否抄对,把计算过程完整写出来的运算。也就是离开原式计算,即递等式计算,要按从左往右的顺序依次计算。一般来说。
  举例?主要掌握的是记住要先算乘:
   25+65+98 =90+98 =188
100-100÷25=100-4=96
250÷50+12×4=5+48=53
 如何脱式计算。在脱式过程中要按运算顺序划出运算顺序线。在计算混合运算时。二要核对从横式抄到草稿竖式的数字、除法、符号是否抄对,要首先计算括号内部,还要做到“三核对”,要写出每一步的过程。在乘除法连继计算时中,一要核对从书上把题抄到作业本上数字,等号要往前,小数点是否点对地方,也就是脱离竖式的计算?   如何脱式计算,不与第一行对齐,抄到横式上是否抄对,有无遗漏什么是脱式计算  脱式计算、减法
