(-0.15)-(-3.25)+2.75—-(-7.5 )=?
(+0.5)+(-3.25)+(-2.75)+(+5.5)
-(+0.5)-(-3.25)+2.75-(+7.
(-0.5)+(+3.25)+(+2.75)+(-6.5)
(-0.5)-(-3.25)-2.75-(+7.5)怎么算
3.25等于()/()
-3-4+19-11+2 、、、、、 (-17)+59+(-37)?还有啦、-0.5-(3.25)+2.75-(+七由二分之1)
-0.5-[-3.25]+2.75-7.5=
(6.8-5.4)* 2.75-0.9
2.75×0.9+2.75×0.1=2.75×(0.9+01)是应用了()
π*7.42+2.58*π/(3.25+π-3.25)
(+0.25)+(3.25)-(-5.75)
-0.5-(-3.25)+2.75-(+7.5)=( )仔细说明
(一0.5)+(十3.25+(十2.75+-5.5
0.78x18÷0.15,0.25x(4+0.4),7.28+3.2÷2.5,3.25x67+5.57x67可以简便算法的简便算
+(-0.15)化简
(-1.5+2.75)÷(-0.25)=
(-8)+3.75+8+(-2.75)
