Evaluating expressions require two things- parentheses and PEMDAS. The video starts with an emphasis on using parentheses to plug in your variables. Once you have everything plugged in, PEMDAS will get your mathematicians to the correct answer. Don't let your learners be confused with exponents and extra parentheses, just follow the order of operations and go step by step to the correct answer.
