my guess is that the real part is -6 while the imaginary part is 2i

 

 

 

my guess is -4 + 11i

 

 

my guess for this one is 14-2i

1) is correct

 

2) don't guess

 

(-3 - i) + (5+6i) = (-3+5) + (-1+6)i = 2+5i

 

3) your guesses.... are not good

 

(8-3i)-(6+i) = (8-6) + (-3-1)i = 2 - 4i
