Subtracting Polynomials with Negative Coefficients

This lesson teaches how to subtract polynomials with negative coefficients using sine number operations. It covers adding zero terms to align exponential terms, understanding directions on a number line, and subtracting negative numbers by adding the opposite. The lesson explains subtracting whole numbers and polynomials using parentheses, applying the distributive property, and combining like terms. It also includes evaluating expressions by substituting values and handling polynomials with few like terms.
