Multiplying Algebraic Expressions

The video tutorial covers the multiplication of algebraic expressions, starting with a review of addition and subtraction of expressions, emphasizing the need for like terms. It then revisits the distributive property and explains the rules for multiplying exponents. The tutorial provides examples of multiplying expressions, including those with negative coefficients, and clarifies the difference between adding and multiplying terms.
