Heh. It's only 50/50 with me.
Ha ha ha then your math was wrong, man.

There's only certain numbers that are possible answers from that. It's one of the oldest math tricks in the book. Go do it again, with 5 different numbers for 5 different solutions. Go through, get the symbol page, and you'll realize that it's the exact same symbol next to all five of your solutions.
Then do it again. While the symbol will change, all five solutions will have the same symbol next to it.
Dumb math trick. (Of course, that doesn't make it any less weird and creepy until you figure it out . . .)
