How often do curves meet?
If you take an equation involving variables x and y, you can draw a graph of its solutions: they form a plane curve. If you have two such equations, you have two curves, and you can ask how many times they intersect each other.
I'll explain why counting these intersections is useful for a range of things: from understanding Pythagoras's equation a2 b2 = c2, to annoying people on the internet, to the cutting edge of mathematics.
I'll show a very simple formula, which happens to be wrong, and explain why it's a good idea to ignore the fact that it's wrong.
