9. jim_thompson5910

you're given z1 and z2 and you want to find z1+z2 right?

10. Katieann16

yes

11. jim_thompson5910

z1 + z2 = (-3, 6) + (4, 2) z1 + z2 = (-3+4, 6+2) z1 + z2 = (1, 8)

12. jim_thompson5910

you just add the corresponding components

13. Katieann16

thats what i put & i got it wrong?

14. jim_thompson5910

well there has to be a typo somewhere

16. jim_thompson5910

it's definitely not (1,9) as you have in the pic, unless (4,2) is really (4,3)

17. jim_thompson5910

oh

18. jim_thompson5910

(1,8) = 1+8i

19. jim_thompson5910

they probably want the answer in a+bi form

20. Katieann16

ohhhhhhhhhh i see

21. jim_thompson5910

(x,y) = x+y*i in general

22. jim_thompson5910

when you have the x axis be the real axis and the y axis be the imaginary axis

ok thank you (:
