Chapter 1 provides an introduction to the properties and operations of Real Numbers. We'll also examine properties of exponents and roots, and then discuss the order in which mathematical operations are to be applied as we simplify algebraic expressions.

In Chapter 2 we'll begin learning techniques to solve linear equations in one variable followed by a discussion of formulas and how to solve problems using them. Next we will apply those skills to real-life situations as we develop a general plan for solving application problems, and specific plans for certain types of problems. We will also learn the processes of solving linear and compound inequalities and finish up the unit by learning how to solve absolute value equations and inequalities.

In Chapter 3 we'll be introduced to the Rectangular Coordinate System. We will learn how to graph lines of equations in two variables. We'll discuss how to determine slope and how to use it to graph lines and find equations of lines. We will also become acquainted with functions, and we'll finish the unit learning how to graph linear inequalities in two variables.

In Chapter 4 we'll start by determining how to graphically find a solution set of two intersecting equations in two variables, known as a system of linear equations, followed by the procedure to solve a system algebraically.

In Chapter 5 we will discover some new properties of exponents along with the properties of polynomial expressions. We will learn how to use scientific notation as a tool for expressing very large and very small numbers. We will exam methods for adding, subtracting, multiplying, and dividing polynomials. We will expand our understanding of functions to include polynomial functions.

In Chapter 6 we will learn how to factor polynomials. Methods to be learned include: factoring by grouping, factoring trinomials, factoring perfect squares and perfect cubes. We finish the unit by focusing on a fundamental approach to factoring, and we will learn problem solving skills when the polynomial is part of an equation.

In Chapter 7 we start learning about rational expressions by examining their properties. From there we will begin the task of learning how to add, subtract, multiply, and divide rational expressions. We will learn two methods for simplifying complex fractions before we tackle solving equations involving rational expressions.

In Chapters 8 & 9 the properties of radical expressions are initially discussed before we take on the task of learning the procedures for simplifying, including the conversion from a radical expression to a rational exponential expression. Next we’ll learn how to add, subtract, multiply, and divide radical expressions. This is followed by a presentation of methods we will use for solving equations containing radical expressions. We finish the unit by focusing on manipulating the polynomial equation into a particular format in a process known as completing the square. Once that process is learned we will use it to derive a generalized formula for solving all quadratic equations.

Academic Honesty:
Academic integrity is the foundation of the academic community. Because each student has the primary responsibility for being academically honest, students are advised to read and understand all sections of this policy relating to standards of conduct and academic life. Park University students and faculty members are encouraged to take advantage of the University resources available for learning about academic honesty ( or Park University 2011-2012 Undergraduate Catalog Page 95-96

Plagiarism involves the use of quotations without quotation marks, the use of quotations without indication of the source, the use of another's idea without acknowledging the source, the submission of a paper, laboratory report, project, or class assignment (any portion of such) prepared by another person, or incorrect paraphrasing. from Park University 2011-2012 Undergraduate Catalog Page 95

Attendance Policy:
Instructors are required to maintain attendance records and to report absences via the online attendance reporting system.

  1. The instructor may excuse absences for valid reasons, but missed work must be made up within the semester/term of enrollment.
  2. Work missed through unexcused absences must also be made up within the semester/term of enrollment, but unexcused absences may carry further penalties.
  3. In the event of two consecutive weeks of unexcused absences in a semester/term of enrollment, the student will be administratively withdrawn, resulting in a grade of "F".
  4. A "Contract for Incomplete" will not be issued to a student who has unexcused or excessive absences recorded for a course.
  5. Students receiving Military Tuition Assistance or Veterans Administration educational benefits must not exceed three unexcused absences in the semester/term of enrollment. Excessive absences will be reported to the appropriate agency and may result in a monetary penalty to the student.
  6. Report of a "F" grade (attendance or academic) resulting from excessive absence for those students who are receiving financial assistance from agencies not mentioned in item 5 above will be reported to the appropriate agency.

Park University 2011-2012 Undergraduate Catalog Page 98
A minimum of six classess must be attended for the full time period or the student will earn an automatic "F" grade.

Disability Guidelines:
Park University is committed to meeting the needs of all students that meet the criteria for special assistance. These guidelines are designed to supply directions to students concerning the information necessary to accomplish this goal. It is Park University's policy to comply fully with federal and state law, including Section 504 of the Rehabilitation Act of 1973 and the Americans with Disabilities Act of 1990, regarding students with disabilities.
