This video is a very basic introduction to what exponents are, what the terms stand for, and how to evaluate bases to an exponent. This lesson explains clearly what it means to have a base raised to an exponent. The concepts are laid out for beginning Algebra students who are just learning about exponents. The difference between the negative sign in the base being inside and outside of parentheses is shown with multiple examples. The major strength of this video is in its many example problems that show many different situations.
