-[-[n-1]]=

-[-[x+y+z-a]]=

-[-[y-x]+[a+2b]]=

-[-[-5x+1]+[8-[x-1]]]=

Answer 1

Zapisz w postaci sumy 

-[2+a]=-2-a=-a-2

-[3-a]=-3+a=a-3

-[-4a-2b]=4a+2b

-[-2x+3y]=2x-3y

-[-3x+2y-4z]=3x-2y+4z

-[2x-3y+4z-5]=-2x+3y-4z+5

 

Doprowadz do najprotszej postaci.

-[y-x+2z]=-y+x-2z

-[-[5w+1]]=minus na minus daje +, wiec =5w+1

-[-[n-1]]=n-1

-[-[x+y+z-a]]=x+y+z-a

-[-[y-x]+[a+2b]]=[y-x]-[a+2b] = y-x-a-2b = -a-2b-x +y

-[-[-5x+1]+[8-[x-1]]]=[-5x+1]-[8-[x-1]]=-5x + 1-8 +[x -1] = -5x+1-8+x-1=-4x-8
