Why do we sometimes need to \""\""switch\""\"" the direction of an inequality symbol in solving an inequality? What could you say if a student described a function as an equation?\n\nHow much do you know...and how much do you need to know?\n\nHelping your students develop a robust understanding of expressions, equations and functions requires that you understand this mathematics deeply. But what does that mean?\n\nThis book focuses on essential knowledge for teachers about expressions, equations and functions..
