The document discusses the order of operations in mathematics. It explains that parentheses, exponents, multiplication/division from left to right, and addition/subtraction from left to right have priority when evaluating expressions. An example expression is worked through step-by-step to demonstrate how to evaluate it based on the order of operations. The document ends with providing some practice problems for readers to work through.
