This is a very brief video clip about Evaluating Expressions Part 1.  # Ex: Evaluate an Expression with Rational Exponents Using Radicals

## By Mathispower4u

This video provides examples of how to evaluate an expressions with rational exponents by writing the expression in radical form and then simplifying.  # Evaluating Expressions with Parentheses

This Screencast was completed using Dabbleboard and shows how changing removing or eliminating parentheses with similar numbers can change the outcome. The instructor reviews the order of operations as she works the same problem in two different ways based on placement of parentheses.  # Evaluating Expressions with Parentheses and Braces and Brackets
