# MATH 080Elementary Algebra I• 5 Cr.

## Description:

First in a two-quarter sequence of basic algebra using a lecture/workshop format. Topics include lines and graphs, systems of equations, linear equations, and applications. Format includes self/group study and individual assistance. Intended for students with little or no algebra. Students must complete both MATH 080 and 085 to have the equivalent of MATH 097. Recommended: Basic arithmetic skills.

## Outcomes:

After completing this class, students should be able to:

• Perform the operations of addition, subtraction, multiplication and division with real numbers.
• Evaluate numerical and algebraic expressions using the Order of Operations.
• Identify and categorize linear equations, identities, and contradictions.
• Solve linear equations.
• Solve application problems by representing the given informtion as a linear equation then solving the equation.
• Identify the exponents and the bases in algebraic expressions that involve exponents.
• Simplify algebraic expressions that involve exponents by using the laws of exponents.
• Utilize a rectangluar coordinate system to geometrically represent the solutions of a linear equation as the graph of a line.
• Utilize a rectangular coordinate system to geometrically represent and identify the solution(s) of a system of two linear equations.
• Solve systems of two linear equations by utilizing the methods of substitution and elimination.
• Solve application problems by representing the given information as a system of two linear equations then solving the system of equations.
