Question

What is the additive inverse of imaginary number?

Answer 1

C=x+iy
additive inverse C'=-(x+iy)
C+C'=0

Answer 2

so we can say that the additive inverse of imaginary number is zero?

Answer 3

no

Answer 4

then what

Answer 5

-.-
0 is the identity of addition

Answer 6

-(x+iy) is the additive inverse?

Answer 7

yes

Answer 8

can you tell me some bit more that what is the difference between additive identity and additvie inverse

Answer 9

ill tell the difference in reall case then its the same to complex
in R if u have a number a then additvie inverse is -a right ?
becouse
a+(-a) =0
and 0 is the additive identity
which means for any a in R
a+0 =a
