A)4 i 13/33 + (-15 i 2/3)=
b)-9+5+(-7)+(-8)+45=
c)41+(-35)+(-27)+70-6=

a)4 i 13/33 + (-15 i 2/3)=
145/33+(-47/3)=
145/33-517/33=-372/33=11i9/33=11i3/11
b)-9+5+(-7)+(-8)+45=26
c)41+(-35)+(-27)+70-6=43

A) 4 i 13/33 -15 i 2/3 /*11 = 4 i 13/33 - 15 i 22/33 = 11 i 9/33 = 11 i 3/11
b) -9 -7 -8 + 45 = -24 + 50 = 26
C) 41 - 35 - 27 + 70 - 6 = -68 + 111 = 43
