I think of math as a thousand little “tricks” you can use to solve a problem – 1 + 1 = 2 is one trick, the pythagorean theorem is another trick, binomial coefficients yet another, and in order to truly master math, you need to have seen most of those tricks, for example by reading about them in a math textbook or having someone (ie a teacher) teach you them.
