Lesson PurposeThe purpose of this lesson is for students to understand that the rules for subtracting polynomials are analogous to the rules for subtracting integers. Students apply the rules of subtraction by building upon previous knowledge and understanding of polynomial terms. Understanding polynomial operations is siginificant because it is the first major area outside of the basic twostep, onevariable algebra problems that are traditionally taught to students at the beginning levels in algebra. The real world often requires that people be able to make sense of multiple variables that are numerous yet related. Understanding the rules of polynomial operations is one way to abstractly model many of those kinds of situations.
