Mr. Buffington from Simplify Academy explains the concepts of opposites and absolute values. Opposites involve changing the sign of a number, while absolute values measure the distance from zero, always resulting in a positive value. The lesson includes visual aids and practice problems to reinforce understanding. Students are encouraged to practice using worksheets and quizzes to solidify their grasp of these mathematical concepts.
