㈢ 400道四年級上冊的脫式計算並有答案。
1、92+92×
解析:此題可以利用乘法結合律,將1與99結合,組成100,再與92相乘,使得運算簡便。
92+92×99
=92×1+92×99
=92×(99+1)
=92×100
=9200
2、6.07+0.4-0.08
解析:此題的小數之前沒有規律不方便計算,可先利用分配律把0.08轉換成0.07+0.01,再利用加法結合律進行簡便計算。
6.07+0.4-0.08
=6.07+0.4-(0.07+0.01)
=6.07+0.4-0.07-0.01
=6.07-0.07+0.4-0.01
=6+0.4-0.01
=6.4-0.01
=6.39
3、8.2-9.6x0.5
解析:此題先計算乘法,再計算減法,脫式演算法如下:
8.2-9.6x0.5
=8.2-4.8
=3.4
4、35x62+70x19
解析:此題先利用乘法分配律把70變換成35成2,再利用乘法分配律的逆運用提取公約數35,最後利用乘法結合律來簡便計算。
35x62+70x19
=35x62+35x2x19
=35x62+35x38
=35×(62+38)
=100×35
=3500
5、24.6-3.98+5.4-6.02
此題利用加法交換結合律,湊整再計算。步驟如下:
24.6-3.98+5.4-6.02
=(24.6+5.4)-(3.98+6.02)
=30-10
=20
㈣ 小學四年級數學 脫式計算什麼意思
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。
加法:把兩個數合並成一個數的運算。
減法:在已知兩個加數的和與其中的一個加數,求另--個Jm數的運算。
乘法:求兩個數乘積的運算。
1、一個數乘整數,是求幾個相同加數和的簡便運算。
2、一個數乘小數,是求這個數的十分之幾、百分之幾、千分之幾……是多少。
3、一個數乘分數,是求這個數的幾分之幾是多少。
除法:已知兩個因數的積與其中的一個因數,求另一個因數的運算。
綜合算式(四則運算)應當注意的地方:
1、如果只有加和減或者只有乘和除,從左往右計算,例如:2+1-1=2,先算2+1的得數,2+1的得數再減1。
2、如果一級運算和二級運算,同時有,先算二級運算
3、如果一級,二級,三級運算(即乘方、開方和對數運算)同時有,先算三級運算再算其他兩級。
4、如果有括弧,要先算括弧里的數(不管它是什麼級的,都要先算)。
5、在括弧裡面,也要先算三級,然後到二級、一級。
(4)小學四年級脫式記算擴展閱讀:
在一個算式中,如果既含有第一級運算又含有第二級運算,那麼,應先算第二級運算,後算第一級運算。即「先算乘法和除法,後算加法和減法」,簡稱「先乘除,後加減」。
同級運算在一個算式中,如果只含有同級運算,應當按照從左到右的次序進行運算。這就是說,只含有加減法,或者只含有乘除法的混合運算,它們的運算順序是從左到右依次計算。
如果要改變上面所說的運算順序,就要用到括弧。常用到的括弧有三種:小括弧,記作();中括弧,記作[ ;大括弧,記作{}.使用括弧的時候,兩邊拉,中間加。要先用小括弧,再用中括弧,最後用大括弧。

400道四年級上冊的脫式計算並有答案。
1、92+92×99 解析:此題可以利用乘法結合律,將1與99結合,組成100,再與92相乘,使得運算簡便。 92+92×99 =92×1+92×99 =92×(99+1) =92×100 =9200 2、6.07+0.4-0.08 解析:此題的小數之前沒有規律不方便計算,可先利用分配律把0.08轉換成0.07+0.01,再利用加法結合律進行簡便計算。 6.07+0.4-0.08 =6.07+0.4-(0.07+0.01) =6.07+0.4-0.07-0.01 =6.07-0.07+0.4-0.01 =6+0.4-0.01 =6.4-0.01 =6.39 3、8.2-9.6x0.5 解析:此題先計算乘法,再計算減法,脫式演算法如下: 8.2-9.6x0.5 =8.2-4.8 =3.4 4、35x62+70x19 解析:此題先利用乘法分配律把70變換成35成2,再利用乘法分配律的逆運用提取公約數35,最後利用乘法結合律來簡便計算。 35x62+70x19 =35x62+35x2x19 =35x62+35x38 =35×(62+38) =100×35 =3500 5、24.6-3.98+5.4-6.02 此題利用加法交換結合律,湊整再計算。步驟如下: 24.6-3.98+5.4-6.02 =(24.6+5.4)-(3.98+6.02) =30-10 =20

㈨ 什麼是四年級脫式計算
脫式計算即遞等式計算,把計算過程完整寫出來的運算,也就是脫離橫式的計算。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。主要掌握的是記住要先算乘、除法,後算加、減法。在乘除法連續計算時中,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。
