DMA 010 Operations With Integers (1 Credit Hour)


Class Hours: .75
Lab Hours: .50
Clinical/Work Experience Hours: 0
Prerequisites: Appropriate placement test scores
Corequisites: None
This course provides a conceptual study of integers and integer operations. Topics include integers, absolute value, exponents, square roots, perimeter and area of basic geometric figures, Pythagorean theorem, and use of the correct order of operations. Upon completion, students should be able to demonstrate an understanding of pertinent concepts and principles and apply this knowledge in the evaluation of expressions.

Competencies:

  • Visually represent an integer and its opposite on the number line
  • Explain the concept of the absolute value of an integer
  • Demonstrate the conceptual understanding of operations with integers to solve application problems
  • Correctly apply commutative and associative properties to integer operations
  • Apply the proper use of exponents and calculate the principal square root of perfect squares
  • Simplify multi-step expression using the rules for order of operations
  • Solve geometric application problems involving area and perimeter of rectangles and triangles, angles, and correctly apply the Pythagorean theorem
