Depending on the context, it can Scale or stretch a number Rotate a vector , without needing sine or cosine And today we’ll see yet another use: listing combinations . Revisiting multiplication has a few uses: It demystifies other parts of math . The binomial theorem, Boolean algebra (used in computer circuits) and even parts of calculus become easier with a new interpretation of “multiplication”. It keeps our brain fresh. Math gives us models to work with , and it’s good to see how one model can have many uses. Even a wrench can drive nails, onc
