Open end is big space (bigger number). Closed end is smaller space (smaller number).

I honestly don't understand how people struggle with this, but maybe it's some kind of light dyslexia. I don't judge people with dyslexia, obviously. It's easy for me, as someone who doesn't have dyslexia, to claim it is easy to see.

I don't know about everyone else but before I figured out the visual clues of the symbols on my own, the only explanation I ever got was "> is greater than, < is less than" but I was a kid and there was nothing stopping me from interpreting "10 < 100" as "100 is less than 10" which confused the hell out of me.

Big side big number, little side little number

If you see it as a function of height, the left side of < has a smaller height than the right side

[–] [email protected] 13 points 19 hours ago (4 children)

I had no idea that people struggled with this so much and have come up with such crazy (to me) ways of figuring it out.

Most of the world, if asked to write down numbers 1-100 on a line, would do so left to right. The < and > symbols are arrows pointing left and right. To the left the numbers decrease (less than) and to the right the numbers increase (greater than).

All this stuff about crocodiles and ducks seems like such a bizarre way to remember it!

[–] dnick 1 points 10 hours ago

Yes, but that's because that's the way your mind interpreted it, it could have just as easily thought that the arrow (little side) should point in the forward direction from left to right, so 'point to the bigger number'.

Basically two completely unrelated things both make sense to you in the same direction, and that happened to be the direction that the the people picking the symbols also picked. If they had simply picked the opposite direction, all the people who currently struggle might find out perfectly natural and be confused as to why 'you' have such a problem understanding it.

A mnemonic device is a mnemonic device.

I think about how the symbols have two sides, one is a point (small side) and the other is wide (big side)

[–] [email protected] 5 points 17 hours ago

Your explanation is no less crazy lol.

[–] [email protected] 2 points 17 hours ago* (last edited 17 hours ago)

I think about it the same way I think about + and -. I don't think at all. I just know.

Maybe it's because I'm a programmer and I encounter comparators more than addition and subtraction.

[–] [email protected] 30 points 1 day ago

I got a zero on a math test in second grade because I said "the bigger number is on the bigger side" instead of "the crocodile wants to eat the bigger number", fuck you 2nd grade math teacher who made me hate math by being the thought police.

[–] [email protected] 4 points 17 hours ago

And then here's me having to have my wife help my daughter with her middle school math assignments because they entirely mystify me.

[–] stevedice 21 points 1 day ago (4 children)

I never understood why so many people seemingly struggle with these signs to the point they need a mnemonic. The big side points to the big number and the small side to the small one. What even is there to remember?

[–] [email protected] 2 points 6 hours ago

As a kid I saw it as an arrow pointing, it points to the small number. That's how I remembered it. I can now understand it 'facing' the big number but it was never pointing any direction other than the point, which is to the smaller one. Now I understand it eats the bigger one but it took awhile to see it as anything but an arrow point, if they drew them with teeth I'd have understood the eating better as a kid but I don't think any teacher did that. I never had trouble understanding overall so wasn't an issue.

[–] [email protected] 7 points 19 hours ago (2 children)

Yeah, the symbol is the mnemonic. What does the crocodile even explain? Why doesn't the bigger number eat the smaller numbers?

[–] [email protected] 1 points 9 hours ago

Yeah the worst part about mnemonics like this is that its easy to think to yourself "crap, does the crocodile eat the bigger number or the smaller number?"

Never been a fan of mnemonics that can be easily flipped because my brain loves to troll me. When I noticed/heard larger side larger number, this was the only way I ever saw it again.

[–] stevedice 2 points 18 hours ago

Yeah. It would be like saying "Oh, when I see a stop sign, I think to myself they're the same colour a traffic light turns to when you're supposed to stop, so I remember to stop"

[–] BlueMagma 1 points 13 hours ago (1 children)

What you describe is a mnemonic.

[–] stevedice 2 points 10 hours ago* (last edited 10 hours ago)

Technically. That's not the point, though. The symbol itself has a built in mnemonic; it's designed so you can't forget what it means. If you wanna be pedantic, which, fair enough, we're talking about math notation after all, add "different" before "mnemonic" in the original comment and the point still stands.

That's Mr. Dr. Professor Postdoc to you!

[–] [email protected] 6 points 20 hours ago (1 children)

I know that you can pronounce the emoticon <3 as less than three and it has for whatever reason replaced the crocodile mnemonic.

It's a thing that I've always thought that people over-complicate. It's just there, the small side with the small number the big side with the big number...

[–] [email protected] 110 points 1 day ago* (last edited 1 day ago) (9 children)

"The entirety of the small number constitutes a relatively smaller portion of the big number. Thus, the open side of > points to the smaller number to indicate that it's a magnified view within the larger number."

I hope this helps overcomplicate things for you. We must all return to crocodile.

For a while, I've seen "<" and ">" as a slanted "=", which is to say, these numbers are not equal, and the larger side is the larger number and the smaller side is the smaller number.

Works for me, IDK.

My Mama says that alligators are ornery because they got all them teeth and no toothbrush

The teacher who first taught me told me “Pac Man wants to get the most points” and that stuck with me

I don't think I've ever been taught a mnemonic with animals

The small number is on the small side of the symbol, the large number is on the large side, it seems pretty intuitive to me, to be honest.

"Points at the smaller thing"

Every time I watch a student stall out on inequalities I ask "it's the crocodile isn't it?". Without fail, they've got confused by it and as soon as they hear "points at the smaller thing" they have no issues.

[–] [email protected] 38 points 1 day ago

yeah its literally a graph. the bigger side is the bigger number. the smaller, surprise, smaller number.

[–] [email protected] 12 points 1 day ago (3 children)

<3 is "less than three", and 3 is "three" so logically < is "less than"

[–] starman2112 12 points 1 day ago (1 children)

I try this, but I always get <3 mixed up with Ɛ>

< is part of a K. The K stands for Kleiner which means smaller in German/Dutch

I earned it as the larger part being on the side of the bigger number

Surely in theoretical physics, the most common use of > is in a ket (eg. |ψ>).

arguably, it's |ψ〉, which is not the same as >
