You simply measure out a length such that, if you drew a square that many meters on a side, and also drew a square 3.1415 meters on a side, they would enclose no area between the two of them. Then evenly divide this length into meters, and for each meter write down 2.7183. Now multiply those numbers together, and you’ll find they make −1. Easy!
