I read this as "What is an even number" and spent the entire article stoked for when he got to the part about a number being even. Still, lovely article.

- oh_sigh 8y agoDon't even numbers have a pretty easy definition? If prime factorizartion of the number contains at least a 2
- mabbo 8y agoOh sure, but then the article started talking about sheep and rocks and I'm like "Oh boy, I bet I totally don't understand what it means to be even!"
- aidenn0 8y agoWell you can reduce the +/- notation further by allowing yourself to (after removing all +/- pairs) to remove pairs of sequential + tokens, and if it reduces to an empty string then it's an even number, otherwise it's an odd number.
