ELEMENTARY ALGEBRA A
Catalog Description:
65A – Elementary Algebra A
3 units
Concepts covered in the first half of Mathematics 65, including signed numbers, polynomials and integer
exponents; linear equations and inequalities; introduction to graphs; set theory. Designed for those with
no previous algebra background. Prerequisite: Mathematics 104, (both completed with a grade of “C” or
higher) or an appropriate skill level demonstrated through the Mathematics Assessment process. May
not receive credit if Mathematics 65 or 65L has been completed. 3 hours lecture, 0-1 hour laboratory.
[Typical contact hours: lecture 52.5, laboratory 0 - 17.5]
