Catalog Description:

65A – Elementary Algebra A 3 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 with a 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 whole numbers, fractions, decimals, and signed numbers without a calculator; 2. apply the commutative and associative properties; 3. use ratios, proportions and percents; 4. identify basic geometric figures and their properties, including Pythagorean Theorem to find lengths of sides, areas and perimeters; 5. calculate the mean and median; 6. convert within and between U.S. Standards and metric units of length, area, volume, mass, temperature, and time; 7. solve simple algebraic equations; 8. use order of operations to simplify arithmetic expressions; 9. evaluate square roots of perfect squares; 10. solve word problems including those using formulas.

Expected Outcome for Students:

Upon completion of the course, the student should be able to:

1. write using set theory notation; 2. apply order of operations to simplify algebraic expressions; 3. solve linear equations in one variable; 4. solve and graph linear inequalities in one variable; 5. graph linear equations in two variables by various methods; 6. add, subtract, multiply, and divide polynomials; 7. apply the formula for squaring the binomial; 8. apply algebraic methods to solve word problems; 9. solve formulas for any given variable; 10. apply the properties of integral exponents; 11. convert between scientific notation and standard notation; 12. find the slope of a line from the graph and from the definition.
