1 + 1 = 0: The Proof!

I’ve seen a few so-called “Maths tricks“ on YouTube, most involving division by zero or basic algebra, so here’s my contribution. You do need to know a bit about square roots and the complex number i, though. Of course, there is a flaw in the proof - the point is for you to spot it. The music is Random by Gary Numan (1979). I didn’t know how to get the “√“ symbol when I did this so “sqrt“ means “√“ throughout.
