In this first Algebra I lecture on Educator.com, Dr. Carleen Eaton will briefly cover the history of algebra, the origin of the word 'algebra' and why it is so powerful compared to arithmetic in solving real world problems. You will then cover basic definitions such as variable, algebraic expression, and operations. The lecture concludes with four examples where you will convert an algebraic expression from a sentence.
