This program covering the basic arithmetic operations of rational numbers consists of two courses: Math 370E and Math 370F. This program is noncredit, lab-based, and can be run as a self-paced and open entry program when appropriate. Students can repeat the program as often as needed to develop foundational numeracy skills. In order to receive the Certificate of Competency in Rational Numbers, the students need to successfully complete these two courses. After completing this certificate, students should be able to demonstrate number sense involving the rational numbers and exhibit skills involving addition, subtraction, multiplication, and division of rational numbers and their applications.
