F. 二年級脫式計算題
脫式計算,即遞等式計算,把計算過程完整寫出來的運算,也就是脫離豎式的計算。在計算混合運算時,通常是一步計算一個算式(逐步計算,等號不能寫在原式上),要寫出每一步的過程。一般來說,等號要往前,不與第一行對齊。也就是離開原式計算。舉例250÷50+12×4=5+48=53如何脫式計算?
如何脫式計算?主要掌握的是記住要先算乘、除法,後算加、減法。在乘除法連繼計算時中,要按從左往右的順序依次計算。遇到括弧,要首先計算括弧內部。在脫式過程中要按運算順序劃出運算順序線,還要做到「三核對」,一要核對從書上把題抄到作業本上數字、符號是否抄對。二要核對從橫式抄到草稿豎式的數字、符號是否抄對。三要核對把草稿豎式上的得數,抄到橫式上是否抄對,小數點是否點對地方,有無遺漏。
