MCQ’s Questions from Number System:
A complex number added to its additive inverse would give?
- Answer A : Multiplicative identity
- Answer B : Additive identity
- Answer C : Additive inverse
- Answer D : Multiplicative inverse
Correct: B
Reason: (a, b) + (-a, -b) = (0, 0) which is the additive identity of complex numbers.
