College Algebra > Section 1 > Topic 1 Topic 1: Fundamental Concepts Of Algebra 1 Topic Objective: At the end of this topic, students will be able to understand: 1. Algebraic Expressions 2. Formulas and Mathematical Models 3. Sets 4. Properties of Real Numbers and Algebraic Expressions 5. Simplifying Algebraic Expressions 6. Exponents and Scientific Notation 7. Radicals and Rational Exponents 8. Polynomials Topic Introduction: Algebra uses letters, such as x and y to represent numbers. If a letter is used to represent various numbers, it is called a variable. Topic Overview: 1. Algebraic Expressions For example, imagine that you are basking in the sun on the beach. We can let x represent the number of minutes that you can stay in the sun without burning with no sunscreen. With a number 6 sunscreen, exposure time without burning is six times as long, or 6 times x . This can be written 6 · x but it is usually expressed as 6 x. Placing a number and a letter next to one another indicates multiplication. Notice that 6 x combines the number 6 and the variable using the operation of multiplication. A combination of variables and numbers using the operations of addition, subtraction, multiplication, or division, as well as powers or roots, is called an algebraic expression . Here are some examples of algebraic expressions: Many algebraic expressions involve exponents . For example, the algebraic Expression 17 x 2 + 261 x = 3257 approximates the average cost of tuition and fees at public U.S. colleges for the school year ending years x after 2000. The expression x 2 means x · x , and is read “ x to the second power” or “ x squared.” The exponent, 2, indicates that the base, x , appears as a factor two times.
