Why would the internet freakout over math?

Why is this upvoted so much?

Is it referencing a song?

I'm going to require Canadians for this won't I?

What?

I play pokemon go and i have no idea what this is referring to

What's up with minecraft China edition

?

I have absolutely zero idea what this means. Am I dumb??

I don’t get it

Need help here. Friend posted this. No idea. Is it bc they're all "Karen's"¿?¿?
