Definitions. Definitions. Definitions. Learning algebra is a little like learning another language. In fact, algebra is a simple language, used to create mathematical models of real-world situations and to handle problems that we can't solve using just arithmetic. Rather than using words, algebra uses symbols to make statements about things. In algebra, we often use letters to represent numbers. Since algebra uses the same symbols as arithmetic for adding, subtracting, multiplying and dividing, you're already familiar with the basic vocabulary. In this lesson, you'll learn some important new vocabulary words, and you'll see how to translate from plain English to the "language" of algebra. The first step in learning to "speak algebra" is learning the definitions of the most commonly used words. Algebraic Expressions | Variables | Coefficients | Constants | Real Numbers | Rational Numbers | Irrational Numbers | Translating Words into Expressions Algebraic expression: 3x2 + 2y + 7xy + 5 a number divided by the same number less five.
