# Elementary Algebra

Course Description:

Prerequisite: MTH 096 with a grade of C or better or an
acceptable score on the current College assessment instrument.
Includes natural numbers, integers, first-degree equations and
inequalities, special products, factoring, rational expressions
and equations, graphs, and linear systems, exponents, and
quadratic equations. This course was previously MTH 107.
You may receive credit in MTH 107 or MTH 097, but not both.
(Equivalent to first year high school algebra). (45-0)
