Answer :
(5i+4) + (4i-3)
5i+4i-3+4
9i - 1
(2+i) - (3+4i)
(2+i) + (-3 - 4i)
-1 -3i
Each part, real numbers and imaginary, are to be taken as separate pieces; add them with and subtract them by each other as you normally would. :)
5i+4i-3+4
9i - 1
(2+i) - (3+4i)
(2+i) + (-3 - 4i)
-1 -3i

Add the real numbers together.
Also perform operation on the imaginary ones as well.
(5i +4) +(4i -3) = 5i + 4i + 4- 3 = 9i +1.
(2+i) - (3+4i) = 2 +i -3 -4i = 2-3 + i - 4i = -1 -3i.
Cheers.
