11 - Simplify Expressions with Imaginary Numbers - Part 1

View more at www.MathTutorDVD.com.
In this lesson, will get practice with simplifying expressions that contain imaginary numbers. What we will find is that imaginary numbers can be added, subtracted, and multiplied and divided. We just need to remember that anytime you square the imaginary number "i" the result of -1. Anytime we need to add imaginary numbers, we add them just like regular algebraic terms.

When teaching what pi is, round it to 3. A student needs to know pi is a locked in ratio-a known number and that’s why pi appears in formulas. For this lesson, yes place values are important. But when teaching pi, it is 3 to 1 circumference to diameter.
