Requirements for AST1XX Classes:

In this course will be working with large numbers and simple linear equations. There are a number of problems in the on-line quizzes that require you to do simple algebra. Graduation standards from high school state that you are proficient in the following skills:

• apply arithmetic operations with fractions and integers (e.g., add and subtract by finding a common denominator, multiply and divide, reduce and perform long division without a calculator)
• use exponents and scientific notation
• use the correct order of arithmetic operations, particularly demonstrating facility with the Distributive Law
• correctly perform addition, subtraction, multiplication and division that includes variables
• simplify and perform basic operations on rational expressions, including finding common denominators (e.g., add, subtract, multiply and divide)
• understand exponents, roots and their properties solve linear equations
• know the definitions of sine, cosine and tangent using right triangle geometry
• solve problems through the use of geometric construction.
• are able to convert between decimal approximations and fractions
• understand relative magnitude.
• know how to make and use estimations plus know when to use an estimation or approximation in place of an exact answer
• know the definition of a mathematical expression (a statement using numbers and symbols to represent mathematical ideas and realworld situations)
• understand the use of written symbols and the limitations on appropriate uses of such symbols (e.g., equal signs, parentheses and superscript)
• understand and use data represented in various ways (e.g., charts, tables, plots and graphs)

This class will sharpen those skills through the study of astronomy.
