a) -5,65 + (-2,08) - 1,35 = -7,73 - 1.35 = -9,08
b) 6,51 + (-2,775) - 11,125 = 3,735 - 11,125 = - 7,39
c) -10/9 + (-1/6) + 9 i 3/4 - (-6,25) = = -1 i 5/18 + 9 i 3/4 + 6,25 = 11 i 1/36 + 6 i 1/4= 17 i 5/18
d) -9,3 - (-12 i 1/5) - (72,8 - (-13,002)) = -9,3 + 12 i 1/5 - (72,8 + 13.002) = 21 i 1/2 - 85,802 = -64,302
