Course Outline for Mathematics 65A

ELEMENTARY ALGEBRA A

Catalog Description:

65A – Elementary Algebra A3 units

Concepts covered in the first half of Mathematics 65, including signed numbers, polynomials and integer exponents; linear equations and inequalities; introduction to graphs; set theory. Designed for those with no previous algebra background. Prerequisite: Mathematics 105 or 105L, (both completed witha grade of C or higher) or an appropriate skill level demonstrated through the Mathematics Assessment process. May not receive credit if Mathematics 65 or 65L has been completed. May be offered in Distance Education delivery format. 3 hours lecture, 0-1 hour laboratory.

Prerequisite Skills:

Before entering the course the student should be able to:

  1. perform computations with fractions, decimals, and signed numbers without a calculator;
  2. build and simplify fractions;
  3. convert between decimals, percents, and fraction representations;
  4. determine the prime factorization of a natural number;
  5. interpret natural number exponents;
  6. apply the associative, commutative, and distributive laws;
  7. apply the order of operations in evaluating expressions;
  8. perform unit conversions in U.S. standard and metric units;
  9. solve problems using ratios, proportions and percents;
  10. find the areas, perimeters, and volumes of geometric figures and objects;
  11. translate between words and the mathematical symbols for variables and operations.

11.interpret operations and variables in algebraic expressions;

12.create, interpret, and solve simple linear equations;

13.graph simple relationships between two variables;

14.solve word problems, including those using formulas and linear equations.
