懂数学的进来(负数乘法)
1.(-2)*(-8)*(-125)
2.0.25*(-3.1)*(-8)
3.-4*(-5)*0.25
4.100*(-3)*(-5)*0.01
5.2.25*(-2.3)*3/25
6.-2.1*6.5*(-3/7)

1.(-2)*(-8)*(-125) = 16 * (-125) = -20002. 0.25*(-3.1)*(-8) = 0.25 * 24.8 = 6.23. -4*(-5)*0.25 = 20 * 0.25 = 54. 100*(-3)*(-5)*0.01 = (-300) * (-0.05) = 155. 2.25*(-2.3)*3/25 = -5.17...
