Question

[(-20*(-2)+(-5)]*(-32)+(-4)*[1-(-10/2)*(-2)]=

(-2,4)*[(-0,75)*8/9-1/6*(-1,5)]-(-4,8):(-1,6)=

5,2-1/5*(-0,5)=

(1/3-0,5):(-0,75)=

/ oznacza kreske ułamkowa

Answer 1

[40+(-5)]*(-32)+(-4)*[1-10]=
35*(-32)+(-4)*(-9)=
-1120+36=-1084

-2,4*[(-3/4)*8/9-1/6*(-15/10)]-(-4,8)*(-10/16)=
-2,4*[-6/9+5/20]+48/10*)*(-10/16)=
-24/10*[-120/180+45/180]+(-48/16)=
-24/10*(-75/180)-3=
180/180-3=1-3=-2

52/10-1/5*(-1/2)=
52/10-(-1/10)=
52/10+1/10=
53/10=5,3

(1/3-1/2)*(-4/3)=(2/6-3/6)*(-4/3)=
(-1/6)*(-4/3)=
4/9
