Course Syllabus for Elementary Algebra I
This course is the first half of a standard one year course in elementary algebra. Topics
to be covered include the concept of a variable ; signed numbers ; evaluation of (algebraic)
expressions; solution of equations and inequalities (in one variable); graphing; and systems
of (linear) equations and inequalities.
Prerequisites: “C” or better in Math 22 or placement in Math 24X
To become familiar with various Real number sets , including the Integers
and Rational numbers.
To acquire skill in solving first degree equations (and inequalities) in one
To acquire a basic understanding of linear equations (and inequalities) in
two variables , including their graphs.
To solve a system of linear equations by various methods .
To develop a basic ability to solve applications using the algebraic techniques
covered throughout the course.
In addition, as in most mathematical courses, students will be presented
with the challenge of utilizing critical thinking along with development of
communicating analyses in an ordered and neat fashion.
