数学脱式计算题?8/7 × 21/16 + 1/2= 3/2+1/2 = 4/2 = 2 五年级脱式计算题带答案和过程 2.5*32*12.5 =2.5*4*12.5*8 =10*100 =1000 五年级上册数学脱式计算题带过程和答案50道 发吧我是五年级下的。那么,数学脱式计算题?一起来了解一下吧。
(1)300÷125÷8=300÷(125×8)=300÷1000=0.3
(2)396-96-172-28 =(396-96)-(172+28)=300-200 = 100
(3)125*24 = 125*8*3 = 1000*3 = 3000
(4)26*15 =(20+6)*15 = 20*15 + 6*15 = 300+90 =390
(5)25*99*4 = 25*4*99 = 100*99 = 9900
(6)250*32 = 250*4*8 = 1000*8 = 8000
运算方式
在四则运算中,加法和减法叫做第一级运算,乘法和除法叫做第二级运算。含有两种或两种以上的运算的算式,通常称为混合运算。加、减、乘、除的混合运算也叫做四则混合运算。在四则混合运算中,规定的计算先后次序,称为运算顺序。数学上规定的四则运算顺序如下:
(1)同级运算在一个算式中,如果只含有同级运算,应当按照从左到右的次序进行运算。
