### Pre-Algebra: Simplifying Algebraic Expressions

http://www.mindbites.com/lesson/1265 for full video You can simplify algebraic expressions by combining like terms. Terms are the part of an expression to be added or subtracted. Terms are called 'like terms' if the variables are the same. A coefficient is the number that is multiplied by a variable in an algebraic expression. In this lesson, Professor Burger demonstrates the commutative, associative, and distributive properties by simplifying several algebraic expressions involving like and unlike terms. Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive Pre-Algebra course.
