## There Is A Hidden Meaning In The Division Sign You've Probably Never Noticed

On Monday, Twitter user Abdul Dremali tweeted an observation about the division symbol that quickly went viral for making everyone see their childhood math lessons differently.

According to BuzzFeed, there’s some anecdotal truth to this idea. While the symbol, known as an obelus, was once used to signify uncertainty in a quotation or even subtraction, it isn’t clear why it was eventually adopted as a division symbol in 1659. But math teachers have used it ever since to help teach students that division is just making two numbers into a simplified fraction—and it isn’t the only symbol in which Twitter users have noted a clever design.

And guess what—‰ is called the permille and ‱ is called the permyriad. You can see how they get their names—per cent means per hundred and per mille means per thousand, derived from Latin. A “myriad” is an outdated way to say ten thousand.

That one’s not technically math, but I bet you never realized that (or, at least I didn’t). For many of these, I just wish I knew the meanings of the symbols when I was struggling in elementary school math.

## Twitter Just Noticed Something Odd On Melania's Birthday Card To Donald

President Trump got a number of birthday shoutouts on Twitter this week, but none stood out more than the casual greeting he received from his wife, Melania.

Not only did she wait until a leisurely 10pm to tweet his birthday greeting, but the card she posted contained a suspicious orange smudge.

Seriously, what IS that thing?

The theories kept coming:

But let’s be honest, we all know what that gross smudge REALLY is…

Everyone loves a good conspiracy theory.

But maybe the Trumps are just bad at birthdays. Let’s not forget the birthday tweet President Trump sent to his wife back in April. You know, the one with the American flag that only had 39 stars?
