Strange...

More random link-hopping tonight, ran across an interesting little exercise here: Answer the following questions as fast as you can: -2+2 -4+4 [...] There's more. I don't want to spoil it, so go there and try this little exercise. Follow the directions. Turned out I am NOT in the minority, and I'd be interested in where you placed. Unfortunately, the rest of the post is over my head. Tagged as Miscellaneous, Science, TASS, The Autonomous Set of Systems
