-4-(-9)-3= -4+9-3 = 5-3=2
-16+7-28= -9-28= -37
(-6,2)+1,6-(-2,3)= -6,2+1,6+2,3= -4,6+2,3= -2,3
7,8-5,4-12,1= 2,4-12,1= -9,7
1 i 1/8-2= 1,125-2=- 0,875
1/4-(-1/2)= 0,25+0,5=0,75
(-2,1)+1/5-3= -2,1+0,2-3=-1,9-3=-4,9
-4-[-9]-3=2
-16+7-28= -37
[-6,2]+1,6-[-2,3]= -2,3
7,8-5,4-12,1= -9,7
1 1/8-2 1/4-[-1/2]=9/8-9/4-[-1/2]=9/8-18/9-[-4/8]= -5/8
[-2,1]+1/5-3=[-2,1]+0,2-3= -4,9
