One such rule is that, for any real numbers x, y, and z...

x * (y + z) = x * y + x * z

We're stating this as fact. These two are always equal. With this, we can build more rules:

x + x = x * 1 + x * 1 [identity]
= x * (1 + 1) [our rule above]
= x * 2

So x + x is the same as doubling x.

A variable is just a stand-in for a value we haven't concretely defined.

We may say "let x be a real number", and that's all it means. It's a real number. Not only do we not know which, we don't care which, but by saying it's a real number we have some rules for its usage.

Someone showed me this old comic I did a long time ago. It got 1.5k upvotes on a furry subreddit lol

He passed out on your couch again... Probably a good idea to wake him up before your housemates come home๐Ÿ’ค๐Ÿบ

Since I'm basically an expert on the topic, I've had to explain to a lot of people why it's bad, and honestly most recognize that and change!

It's also an issue with the wider gay community (and contributes to my reluctance to be involved in it).

I think the furry community as a whole needs to have a serious conversation about body groups, shaming, and stereotypes.

Not briefs, boxer briefs. They're like boxers but tighter.

You likely won't ever see Keff in a jockstrap, sorry. I don't like 'em.

Boxer briefs though...
