Adding Polynomials by Combining Like Terms

This video tutorial teaches how to add polynomials by combining like terms. It clarifies common misconceptions, such as the incorrect addition of exponents, and explains the importance of aligning terms by degree. The tutorial uses examples and algebra tiles to demonstrate the process, emphasizing that polynomial addition is closed under addition, meaning the sum of polynomials is always a polynomial. The video also highlights the differences between polynomial addition and whole number addition, particularly the absence of carrying or trading.
