一、du5.4÷1.8+240×1.5 =3+360 =363二、zhi9000÷72×(1.25×0.7×8) =9000÷72×7 =125×7 =875
三、61-(1.25+2.5×0.
7) =61-3 =58四、[(10-0.8)+9.85]-2÷0.
125 =19.05-2÷0.125 =19.
05-16 =3.05 1、脫式計dao
算,回即遞等式計算,需將一系列的數字逐步計答算。在脫式計算中要先算乘、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,在四則運算中,加法和減法叫做第一級運算,乘法和除法叫做第二級運算。
2、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。遇到括號,要首先計算括號內部。
3、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。
