I talk to a lot of people who think that math is just a string of formulas, equations, and rules that someone just made up. They think that if you want to be good at math, you should memorize all the formulas and follow all the rules, just the way the teacher tells you, and then you get an “A.” Boring! No wonder so many people ask, “When will I ever use this math?”

Luckily math is not just about memorizing formulas and rules....
