-7+(-3)+6+(-5)+14+(-8)= -7-3+6-5+14-8 = -10 -1 +6 = -11+6 = -5

16+(-8)+(-11)+5+(-17)+(-5)= 16-8-11+5-17-5 = 8 -6 -22 = 2-22= -20

-8,3+(-9,8)+4+(-11,1)+16+(-15,4)= -8,3-9,8+4-11,1+16-15,4 = -24,6

3 1/2+(-6 3/4)+(-2 3/8)+1,5+(-2 5/8)= 3 1/2 -6 3/4 - 2 3/8 + 1 1/2 - 2 5/8 = 3 4/8 - 6 6/8 - 2 3/8 + 1 4/8 - 2 5/8 = -3 2/8 = -3 1/4 = -3,25
