A friend asked: Why are we taught math topics that are not going to be useful in real-life? Why do we have to learn Algebra 2, for example, when there hands-on skills that lead to jobs without knowing how to graph a rational function, solve for x, or later on in calculus 1, take the derivative of f(x)? It's the same common, lazy question typically asked by people searching for an easy way out of school. How do you reply to someone asking this silly question? I think math helps in terms of paying attention to detail, a skill most people lack. I think the main culprit is laziness. What do you say?
