Adding and Subtracting Imaginary and Complex Numbers

This video is a math tutorial about adding and subtracting imaginary and complex numbers.

It starts with explaining what imaginary numbers are (the square root of a negative number) and how they are represented using the letter "i". Then it shows how to simplify expressions with imaginary numbers, including those with radicals.

The video also covers how to write complex numbers in the standard "a + bi" form, where "a" is the real part and "bi" is the imaginary part. It demonstrates this with examples involving combining like terms and simplifying expressions with both real and imaginary numbers.

Essentially, this video provides a step-by-step guide on how to work with imaginary and complex numbers in various mathematical operations.
