[(-2)x(-3)+(-5)]x (-32)+(-4)x[1-(-5)x(-2)] =[6-5] x (-36)x[6x(-2)=1x(-36)x(-12)=(-36)x(-12)=432

[(-2)x(-3)+(-5)]x (-32)+(-4)x[1-(-5)x(-2)] = 68

(1/3-0,5):(-0,75)=2/9

[(-2)x(-3)+(-5)]x(-32)+(-4)x[1-(-5)x(-2)=[6+(-5)]*(-36)*[-12]=-36*(-12)=432
(1/3-0,5)÷(-0,75)=(1/3-1/2)÷(-3/4)=(2/6-3/6)÷(-3/4)=-1/6*(-4/3)=4/18
