3、 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。

4、一般来说，等号要往前，不与行对齐。

5、也就是离开原式计算。

6、 (脱字念tuo)主要掌握的是记住要先算乘、除法，后算加、减法。

7、在乘除法连续计算时中，要按从左往右的顺序依次计算。

8、遇到括号，要首先计算括号内部。

9、 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。

10、二要核对从横式抄到草稿竖式的数字、符号是否抄对。

11、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。
