A large group of students shares the belief that practical mathematical skills are some kind of an extremely exotic ability that cannot be useful in an ordinary life. This is a common beginner’s mistake. The main purpose of a mathematical curriculum is not to teach students how to multiply and how to extrapolate. Of course, these abilities will be utterly helpful when a student gets an assignment on writing a chemistry lab report example. However, these courses were designed to focus the student’s attention on a complete understanding of fundamental mathematical rules that form the basis of a present-day scientific picture of the world. This is not a question about how to get practical skills in algebra and geometry. It is a question about an irreversible change of the way of thinking.
