0.5+(-4又1/4)-(+2.75)-(-6又1/2)我要算式啊0.5+(-4又1/4)-(+2.75)-(-6又1/2)我要算式啊0.5+(-4又1/4)-(+2.75)-(-6又1/2)我要算
0.5+(-4又1/4)-(+2.75)-(-6又1/2) 我要算式啊
0.5+(-4又1/4)-(+2.75)-(-6又1/2) 我要算式啊
0.5+(-4又1/4)-(+2.75)-(-6又1/2) 我要算式啊
0.5+(-4又1/4)-(+2.75)-(-6又1/2)
=0.5+6又1/2-(4又1/4+2.75)
=7-7
=0
带过程后给+分一:(-5又1/6)-(-1又3/4)-(3又5/6)-(-12又4/7)-(12又4/7)二:(-0.5)-(-3又3/4)+(-2.75)-(5又1/2)三:-1/2+1/3-1/4-1/5+1/6四:-32又1/3-[5又1/4+(-3又1/9)-525-2又6/7修正:第四题是:-32又1/3-[5又1/4+(-3又1/9)-5.2
(-4.09)-(-6又4分之一1) (-8又5分之4)-(-2.8) -0.5-(-3又4分之1)+2.75-7又2分之1|-7又2分之1|-|-9又2分之1| |-7又2分之1-(-9又2分之1)| -32又3分之1+5又4分之1+3又7分之1-5又4分之1+12又7分之6
14又6/1-2.75+1.5-3又4/1
0.5+(-4又1/4)-(+2.75)-(-6又1/2) 我要算式啊
计算:0.5-(-3又4分之1)+(1+2.75)-(+5又2分之1)
负0.5减负3又4分之1加2.75减7又2分之1
(-0.5)-(-3又4分之1)+2.75-(+7又2分之1)
(-0.5)+3又4分之1+2.75+(-5又2分之1)
﹙﹣0.5﹚-[﹣3又4分之1]+2.75-[7又2分之1]
﹣0.5-3又4分之1+(﹣2.75)+7又2分之1
(-0.5)+3又4分之1+2.75+(5又2分之1)怎么做
(负0.5)+3又4分之1+2.75+(负7又2分之1)
(负0.5)-(负3又4分之1)+2.75-(正7又2分之1)
-0.5-(-3又4分子1)+2.75-+7又2分之1
(﹣0.5)+(+3又4分之1)+(+2.75)+(﹣5又2分之1)
(-0.5)+3又1/4+2.75+(-5又1/2)等于多少?
(-0.5)+(3又1/4)+2.75+(-5又1/2) =
(-0.5)+3又4分之3+2.75+(-5又2分之1)要过程
