Pre-Algebra Tutorial Videos

In this area we build the foundation of Algebra as we study the topic of Pre-Algebra.  In this online math course, we will learn in detail about negative and positive numbers, exponents, order of operation, basic equations, and much more!

Section 1: Real Numbers and their Graphs

 Section 2: The Number Line In this section, the concept of the number line is introduced and explained in detail. The concept of a negative number is illustrated by examples from everyday life and their relationship to positive numbers is shown on the number line. The student practices using the number line through numerous examples in this section, including basic addition and subtraction of integers. . . . View the lesson
 Section 3: Greater Than, Less Than, Equal To In this section, the student learns how to properly use the greater than, less than, and equal to symbols in Pre-Algebra. Numerous problems illustrate how to compare positive or negative numbers with these symbols. The number line is used as a graphical reference to reinforce the concept. . . . View the lesson
 Section 4: Adding Integers In this section, the student learns how to add two integers together and get the correct answer every time. Numerous examples of adding positive and negative numbers together are presented and by the end of the lesson the student will have memorized the simple rules for integer addition. The number line is also used to reinforce the concept. . . . View the lesson
 Section 5: Subtracting Integers In this section, the student learns how to subtract two integers from one another and get the correct answer every time. Numerous examples of subtracting positive and negative numbers together are presented and by the end of the lesson the student will have memorized the simple rules for integer subtraction. The number line is also used to reinforce the concept. . . . View the lesson
 Section 6: Multiplying Integers In this section, the student learns how to multiply two or more integers together. We begin the section by explaining the rules of integer multiplication. Next, we work numerous problems which give the student extra practice in multiplying negative and positive numbers together. . . . View the lesson
 Section 7: Dividing Integers In this section, the student learns how to divide integers. We begin the section by explaining the rules of integer division. Next, we work numerous problems which give the student extra practice in dividing negative and positive numbers together. . . . View the lesson
 Section 8: Powers and Exponents In this section, the student learns about the concept of an exponent and how it relates to pre-algebra. Numerous examples are provided to solidify this concept prior to moving on the the multiplication and division rule of terms that have exponents with the same base. . . . View the lesson
 Section 9: Order of Operations In this section, the student learns about the concept of the order of operations in pre-algebra. This deals with understanding what order the student should perform calculations in an algebraic expression. . . . View the lesson
