### Left

### Course Prerequisites:

One of:

- Credit or concurrent registration in MATH 077
- Appropriate score on the math placement test.

### Course Description

This course covers a practical breadth of mathematics, with a focus on math encountered in everyday life. It aims to show the relevancy and usefulness of mathematics and to make it meaningful by putting it in an appropriate context. In this course there is a focus on problem solving with a hands-on and learn-by-doing approach.

### Course Topics:

- Unit I: Geometry, Measurement, and Unit Analysis – Chapters 1 and 2
- Unit II: Linear Equations – Chapter 3
- Unit III: Personal Finances – Chapters 4, 5, and 6
- Unit IV: Statistics – Chapters 10, 11, and 12

### Credit Awarded

4 hours of credit (some exceptions noted below)

Credit is not given for Math 110 if the student has credit in MATH 121, MATH 165, MATH 170, MATH 180, or the equivalent. **No graduation credit is given for architecture, business administration, or engineering students**. This course *may* serve as a prerequisite for statistics courses in the social sciences. This *does not* replace Math 090 as a prerequisite for any other mathematics department course.
