Exploring Adding and Subtracting Polynomials

This video tutorial introduces students to adding and subtracting polynomials. It begins with tips for effective video learning, then explains monomials and how to add and subtract them. The tutorial progresses to adding polynomials by combining like terms and concludes with instructions on subtracting polynomials, emphasizing the importance of distributing negatives.

What should you do if a part of the video tutorial goes too fast?

• Skip the part and continue

• Pause and rewind the video
