帮忙出几道有理数计算吧~仿:-3×(1/8-1/3+1/4)×8-|1/4-1/2| 几次方的也来点.一共20道.

(-10)-(-16)-13*(-16)
(-14)+4-19-12
3*1*17/(-10)
6+(-12)+15-(-15)
15/9/13+(-7)
2/(-10)*1-(-8)
11/(-19)+(-14)-5
15-[1-(20-4)]
-40-28-(-19)+(-24)
22.54+(-4.4)+(-12.54)+4.4
自己好好想想。。。。。
(1) (-17)*(-9)-20+(-6)
(2) (-5)/12-(-16)*(-15)
(3) (-3)-13*(-5)*13
(4) 5+(-7)+17-10
(5) (-10)-(-16)-13*(-16)
(6) (-14)+4-19-12
(7) 5*13/14/(-10)
(8) 3*1*17/(-10)
(9) 6+(-12)+15-(-15)
(10) 15/9/13+(-7)
(11) 2/(-10)*1-(-8)
(12) 11/(-19)+(-14)-5
(13) 15-[1-(20-4)]
(14) -40-28-(-19)+(-24)
(15) 22.54+(-4.4)+(-12.54)+4.4
(16) [-|98|+76+(-87)]*23[56+(-75)-(7)]-(8+4+3)
(17) 32.52-(6+9.728÷3.2)×2.5 87(58+37)÷(64-9×5)
(18) [(7.1-5.6)×0.9-1.15] ÷2.5 (3.2×1.5+2.5)÷1.6
(19) 5.4÷[2.6×(3.7-2.9)+0.62] 12×6÷(12-7.2)-6
(20) 6.5×(4.8-1.2×4)= 0.68×1.9+0.32×1.9
