To Explain:How to add two

Explanation of Solution
Given: Explain to your friend how you would add two complex numbers and how you would multiply two complex numbers. Explain any differences in the two explanations.
Adding two complex numbers
For adding two complex numbers we separate real and the imaginary parts and add them separately and then combine them back.
For example:
Multiplying two complex numbers
For multiplying two complex numbers we multiply the real part of the first number to the second complex number and then multiply the imaginary part with the second complex number.
