## Course Info for MAT098 - PREALGEBRA

This course reviews fundamental mathematical skills in preparation for introductory college algebra. Course topics include the study of real numbers including integers, fractions and decimals; algebraic expressions; linear equations and an introduction to graphing on the coordinate plane. Near the end of the course, students will complete a comprehensive, departmental final exam to assess their preparedness to move on to MAT100 Introductory Algebra.

*Students must earn a CN or better to pass the course.

**PREREQUISITE:** Required on basis of placement test results.

**COREQUISITE:** MAT090, if indicated by placement

Note regarding students who are concurrently enrolled in MAT090 and MAT098:

- If a student is concurrently enrolled in MAT090 and MAT098 and subsequently withdraws or is involuntarily withdrawn from either course, the student will be withdrawn from the other course.
- A student who does not successfully complete MAT090 will receive a grade of RN in the corresponding section of MAT098 during the same semester.
