Well, we never did.

i just found out that the division symbol (÷) is just a blank fraction with dots replacing the numerator and denominator. oh my god.

Turns out that was only the start.

The = symbol was specifically designed to be two lines of visibly equal length. Unbeatable design.

What?

in addition to the percent % there is also a ‰ for thousandths and ‱ for ten thousandths

No!

‰ is called the permille while ‱ is the PERMYRIAD

Get away.

The Percent sign's almost-vertical line & two circles are the components of the number "100", arranged like a fraction.

"/, o, o" => "100"

Can't handle this. I'm still dealing with the reality that Natalie Imbruglia's rendition of "Torn" is a cover.

And there’s this.

Another one, never saw it till I knew it. The power icon on all electronics, the line though a circle is actually binary, 1 is on 0 is off

Wait a minute, it's not a dagger/sword cutting through the complete circuit for off, and being taken away to complete the circuit for on?
