Your Algebra Homework Can Now Be Easier Than Ever!

Pre algebra

Course Description
This course is de signed primarily for students who know the fundamentals of arithmetic, and have
had little or no background in algebra. The course strengthens the student's arithmetic and informal
geometry skills, provides an introduction to the abstractions of algebra using fundamental principles
of rational numbers, order of operations , and solving linear equations . Students may enroll in Math
030 in a lecture section for four units of credit, or individual one-unit modules 030A, 030B, 030C,
and 030D in the Math and Science Center (MSC). Instruction in the MSC sections is given on an
independent tutorial, open-entry basis which must be taken sequentially in the MSC over a
maximum period of 24 months.

4 Unitsl4 Hours of Lecture per week or Individualized Instruction per Week.
