Math 112 - Algebra
- Prerequisites: Intermediate math competence (usually 3 units of HS math) and suitable placement scores, or Math 100 or 101.
- Frequency: Fall (I), Winter (II), Summer (SS)
- Student Body: This course is meant for students who need a background in algebra for calculus and as a terminal course for those who need to fulfill their QR A requirement.
- Credits: 3. Students may not receive credit for both Math 112 and 114. (q-E)
- Recent Texts: College Algebra, 5th ed. (Cohen)
- Course Coordinator: Joel Robbin
- Background and Goals: The main focus of Math 112 is preparation for continued work in mathematics, especially in the various calculus sequences. At the same time it incorporates instruction in quantitative reasoning skills so that it satisfies the Quantitative Reasoning A requirement.
- Alternatives: Math 112 and Math 113 are equivalent to Math 114.
- Subsequent Courses: students who plan to take calculus need to go into Math 113 (Trigonometry)
