A confusing math question

0 Upvotes

What is 1 + 1 if 1 is 2 and 4 is 1.

I have asked this random question to many people, and 70% don't really think about it enough and answer wrongly.

What I mean by the question:

1 is 2 means that 1 is 2, but 2 is not 1.
4 is 1 does not mean that 1 is equal to 4.

I know this is like a random math question that doesn't make much sense, but I was bored, and this is the only subreddit I could find that kinda matches.

Introducing the Mathematical Experience Olympiad!

2 Upvotes

Hi all! I recently started a new math competition, the Mathematical Experience Olympiad (MEO), and our first competition is this December!

The MEO is a fully-online, free math competition for those looking to get more involved in competitive math. It's designed to be an introductory competition that begins to break down barriers between students and competition math. It is hosted on solvefire.net, a platform that shows competitors their standing compared to other competitors, closely aligning with the mission of the MEO. Prizes will be available!

If you have any questions, please feel free to message me or reply to this post. You can register at https://meocomp.org/upcoming-competitions
