ELL Math NOTES Name _______________________ Questions/Main Topic: Components of an Expression _______ Period Date_________ Ideas CLO: Identify and label each of the components of an algebraic expression. Vocabulary: Expressions An algebraic expression is one or more algebraic terms in a phrase. It can include , phrase: , and symbols, such as plus and minus signs. It's only a phrase, not the whole sentence, so it doesn't include an equal sign. Algebraic expression: whole: 3x2 + 2y + 7xy + 5 In an algebraic , terms are the elements separated by the plus or minus signs. it doesn’t include: This example has four terms, 3x2, 2y, 7xy, and 5. Terms may consist of and coefficients, or constants. separated: Variables actually: In algebraic expressions, letters represent variables. These letters are actually numbers in disguise. in disguise: In this expression, the variables are x and y. We call these letters "variables" because the numbers they represent can vary: that is, we can substitute one or more numbers for the letters in the expression. Coefficients consist: Coefficients are the number part of the terms with variables. In 3x2 + 2y + 7xy + 5, the coefficient of the term is 3. The coefficient of the second term is 2, and the coefficient of the third term is 7. If a term consists of only variables, its coefficient is 1. Constants
