Lesson Summary:
Part 1 of Multiplying Polynomials teaches how to multiply a monomial by a monomial and a monomial by a polynomial. The process involves multiplying coefficients and adding exponents with the same base. Decimals can also be multiplied by ignoring them at first and moving the decimal point later. The distributive property is used to multiply a monomial by a polynomial, and the signs must be carefully considered. Multiple examples are provided for practice.
Lesson Description:
