Imagine that I'm writing some LaTeX code. I start a comment, but change my mind. %

Now I'm just kind of trucking along, doing some math and stuff. For instance, $3 + 4 = 7$. But maybe I'm getting really crazy and I use subtraction. It's kind of an obscure technique, but often it goes a bit like this: let $x = 2 + 2$, so $x - 1 = 3$ (quick maths).

That's OK I guess, but now look at this cool thing called set theory: $\\{n + 42 : n \\in \\mathbb{N}\\}$. Wow. Neat. But we all know why we're really here. If you peer deep down into your heart, and you stare into the depths of yourself: is $P = NP$? Beware, though; many have tried and failed to answer this question. It is by no means for the faint of heart.\
