Tutorial - Adding two imaginary numbers together ex 12, 5i + 7i

The video tutorial explains how to combine complex numbers by treating them as terms to be added. It starts with a basic introduction to complex numbers, followed by examples of combining real numbers and like terms with variables. The tutorial then demonstrates how to apply the same principles to complex numbers, resulting in a simplified expression.

What is the first step in combining complex numbers?

• Subtract the imaginary parts

• Multiply the real parts

• Divide the coefficients
