a) 105-7-13+20=98-13+20=105

b) -16+67-10-7+66=51-10-7+66=41-7+66=34+66=100

c) 2 i 2/5+(-4,1)+7 i 3/5+(-5,9)= 12/5+4 i 1/10+38/5+(-5 i 9/10)=12/5+41/10+38/5-59/10=24/10 + 41/10 + 76/10 - 59/10= 82/10 = 8 i 2/10 = 8 i 1/5

d) 32/7 + 5 i 4/10 - 11/7 - 7 i 4/10 = 32/7 + 54/10 - 11/7 - 74/10 = 320/70 + 378/70 - 110/70 - 518/70 = 70/70 = 1

e) -0.75 + 6,3 + (-1,1) + (-1/4) + (-6,3) = -0,75 + 6,3 - 1,1 - 0,25 - 6,3 = -2,1
