# MTH4419 CONTEMPORARY MATHEMATICS COURSE PROCEDURE

## MTH4419 CONTEMPORARY MATHEMATICS

### 3 Credit Hour

Student Level: This course is open to students on the college level in either the freshman or sophomore year.

#### MTH4419 - Contemporary Mathematics (3 hrs)

The mathematics of problem solving, geometry of shapes, number systems, statistics, functions and set theory.  Note: This will not satisfy courses specifically designating college Algebra as a prerequisite.

#### Course Classification: Lecture

Prerequisites: Minimum grade of C in MTH 4410 Intermediate Algebra or the equivalent, or placed based on mathematics course placement guidelines.

Controlling Purpose: This course is designed to meet the needs of students majoring in nontechnical degree programs that do not require courses for which college algebra is a prerequisite, and for students who wish to survey some practical applications of mathematics to non-technical or nonSTEM fields.

Learner Outcomes: Upon completion of this course, the student will gain understanding of mathematics and problem solving.  This course covers topics such as decision-making, geometry of shapes, statistics, functions and graphs, set theory and numerical systems. Prepares students for the mathematics encountered in other college courses that use quantitative reasoning. Emphasis on developing critical thinking and quantitative reasoning skills needed to understand major issues in society.
