(+3/4)-(+6.25)-(-8 1/2)-(+0.75)-22 1/4=?
7又4分之3-(+6.25)-(-8又2分之1)-0.75-(-22又4分之1)
+17*3/4-(+6.25)-(-8*1/2)-0.75-22*1/4
(+17又3/4)-(6.25)-(-8又1/2)-(+0.75)-22又1/4
1.(-2 3/4)+(+12 5/7)+(-4.125)+(+0.75)+(+1/8);
计算:(-2又3/4)+1又2/3+0.75+(+1/8)+(-3.125)
0.75+0.125+(-2又3/4)+(-4又1/8)=?
(0.75-3/16)*(2/9+1/3)= 18/35除以0.6*2/3= 35/64除以(1/8+3/4)=
(0.064)^-1/3-(-7/8)^0+[(-2)^3]^-4/3+16^-0.75+0.01^1/2
(+71/4)-(+6.25)-(-17/2)-(+0.75)-89/4
(- 2又4分之3 )+( + 12又7分之5 )+(+ 0.75)+(+ 8分之1 )+(- 4.125 )
