Adding and Subtracting Polynomials Explained

The video tutorial by Mr. Wht from Fort Ben Tutoring covers the topic of adding polynomials. It begins with an introduction to like terms and their importance in polynomial addition. The tutorial then walks through several example problems, demonstrating how to combine like terms, arrange terms in descending and alphabetical order, and simplify expressions by removing unnecessary parentheses. The video also covers the distribution of scalars in polynomial expressions. Each problem is solved step-by-step, with explanations of the mathematical principles involved.
