標題:

(-8)-(+3)(-2)-(-4)(+5) = ???

發問:

(-8)-(+3)(-2)-(-4)(+5) = ??? [(+8)-(-4)(+3)]除[(+2)(-2)] =??? [(+3)-(-4)(-5)]除[(-4)(-3)] =???

最佳解答:

1.) (-8)-(+3)(-2)-(-4)(+5) =(-8)-(-6)-(-20) =(-8)+6+20 =26-8 =18 2.) [(+8)-(-4)(+3)]/[(+2)(-2)] =[8-(-12)]/(-4) =(8+12)/(-4) =20/(-4) =(-5) 3.) [(+3)-(-4)(-5)]/[(-4)(-3)] =(3-20)/12 =(-17)/12 =1又(-5)/12

其他解答:

(-8)-(+3)(-2)-(-4)(+5) =-8-(-6)-(-4)(+5) =-8+6-(-20) =-8+6+20 =-8+26 =18 [(+8)-(-4)(+3)]除[(+2)(-2)] =(8)-(-12)/(+2)(-2) =(+8)+(+12)/-4 =+20/-4 =-5 [(+3)-(-4)(-5)]除[(-4)(-3)] =(+3)-(+20)/(-4)(-3) =3-(+20)/+12 =3-20/+12 =-17/12 =1[5/12]|||||(-8)-(+3)(-2)-(-4)(+5) = (-8)-(-6)-(-20) = (-8)+6+20 = 34 = 18 [(+8)-(-4)(+3)]除[(+2)(-2)] = [(+8)-(-12)]/[-4] = 20/(-4) = (-5) [(+3)-(-4)(-5)]除[(-4)(-3)] = [3-(+20)]/[12] = (-17)/12 = (-1.4167)|||||(-8)-(+3)(-2)-(-4)(+5) =+18 [(+8)-(-4)(+3)]除[(+2)(-2)] =-5 [(+3)-(-4)(-5)]除[(-4)(-3)] =-17/126A560DB68EC65D60
