This document discusses multiplying monomials and powers. It defines a monomial as a number, variable, or the product of a number and variable with no division. To multiply monomials with the same base, add the exponents. When multiplying terms with the same variable base but different coefficients, multiply the coefficients and add the exponents. Powers can be multiplied by multiplying the exponents, and powers can be raised to another power by multiplying those exponents.
