Question

Are sums of two complex numbers also complex?

Answer 1

Yes, but not necessarily Real.

Answer 2

yes u see complex nos is the universal set and others are subsets

Answer 3

(a + ib) + (c + id) = a+c + i(b+d), so complex, BUT if b+d = 0 then the imaginery part will be zero, so you'll end up with a real number. But IN GENERAL, the sum of two complex numbers is complex.
