Terms, Factors And Coefficients
Gbogbo ọrọ náà
Before you can manipulate an algebraic expression, you need to read it correctly. Terms, factors and coefficients are the basic vocabulary of algebra, the parts of speech that let you describe exactly what an expression is made of and how its pieces fit together.
In this lesson you will identify the terms, factors and coefficients of an expression, and interpret expressions in context. Getting this vocabulary right is the foundation for collecting like terms, factorizing, and every algebraic technique that follows.
