Adding and Subtracting Polynomials in Algebra 1

Mrs. Yaod introduces Algebra 1 students to polynomials, focusing on adding and subtracting them. The lesson covers monomials, their degrees, and how they form polynomials. It explains binomials and trinomials, standard form, and the concept of closure in operations. Students are guided through practice problems to reinforce their understanding.
