(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)×2.587(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
