Mastering Complex Number Addition

The video tutorial explains how to add two complex numbers, 5 + 2i and 3 - 7i. It demonstrates that when adding complex numbers, you add the real parts together and the imaginary parts together. The tutorial walks through the process step-by-step, showing that the sum of the real parts (5 + 3) is 8, and the sum of the imaginary parts (2i - 7i) is -5i. Thus, the result of adding these two complex numbers is 8 - 5i.

What are the two complex numbers we are asked to add?

• 5 + 2i and 3 - 7i

• 5 - 2i and 3 - 7i

• 5 + 2i and 3 + 7i

• 5 + 7i and 3 - 2i
