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…
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.
But shouldn’t it be 8 < 1 because the eight is heavier and squeezes the bars of the = together?
I’m with you, the croc is an opportunist and will eat the smaller, easier prey.
But shouldn’t it be 8 < 1
That would be a pair of scissors, on its way to cut the number 1.
No, since it’s bigger it stretches the lines apart :)
Whoever my first teacher who taught me this did over complicate it, because when I wrapped my brain around bigger side equals bigger number and smaller side equals smaller (much later than I should have) it was a revelation and also seemed ridiculous it didn’t start out that simple.
I agree. It’s totally simple and people overcomplicate.
BTW one nice thing about German is, that you can even use the same logic for Boolean operators: The AND operator ∧ is called UND being the shorter word (when you put the name at the top). The OR operator ∨ is called ODER being the longer word.
You can use the same logic in English if you Place AND/OR at the bottom instead 😁
I always remember those as “knife” and “cup”, but you have to know that I use my cups the wrong way around.
When you have two things AB on a table and you come in with a knife or cup (NB: upside down) from above, the knife will separate them “A or B” while the cup will catch them together like a pair of angry wasps “A and B”.
“It’s always pointing to the smaller number” is what my elementary teacher said 2<3
The teacher who first taught me told me “Pac Man wants to get the most points” and that stuck with me
Thanks I finally understood this thread, kept thinking people were viewing the crocodile/duck/whatever from above
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.
I learned it that way, along with the = sign showing the sides are equal. But by the time I was teaching, we used Pac-Man, drawing the rest of him around the hungry mouth. I still added “another way to look at it is,” and described the spaces:
Big>little same=same little<Big
Because it doesn’t matter how your mind makes the connection, as long as it works for you.
Edit to add:Pac-people are easier to draw than crocodiles
The Nemo file manager still managed to fuck it up. ‘Triangle pointing down means small filesizes on top, yeah?’
It is weird that Z is considered a bigger letter than A. If triangle pointing down means descending order, it would be Z-A. Ergo, it must mean ascending order and small filesizes are on top just like small letters are on top.
big side, big number
Once I saw a (tailless) cow wearing uniform.
I also have a theoretical degree in physics
You’re theoretically hired!
I’m a mechanical engineer, and I often have to do a double thumbs up with my hands like b_d. It’s the only way I can remember what comes first in the alphabet. In danish you spell boat båd, and if you mess up the order the b and d will be on the outside of the boat and drown, like dåb. Still works 20 years later
Do you have dyslexia or something like that by chance? I don’t think I’ve met anyone who gets confused between b and d. (No offense, I’m just intrigued)
I don’t have dyslexia. But I did only learn how to read and write in 5th grade.
I still have to mentally sing the alphabet song to double check I got the order right.
Am librarian and can confirm: we all do this. It mostly comes up when shelving or retrieving books.
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?
Yeah, the symbol is the mnemonic. What does the crocodile even explain? Why doesn’t the bigger number eat the smaller numbers?
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.
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”
What you describe is a mnemonic.
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.
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.
I am 54, and still every fucking time.
Never heard this till this meme, apparently I was under a rock… Or in Florida
Not a meme, just how I was taught to remember greater than / less then operator direction
Yeah I meant the saying from the meme op posted, my bad. We just were taught the bigger side faces the bigger side, smaller smaller. Alligators, Crocodiles, and Pacman I guess we never included in math otherwise we’d startt totalling how many neighborhood dogs got eaten in the retention ponds next door. Like the number 1 unspoken rule of going fishing on the St. Johns River is don’t bring your dog, haha
Also I have seen Lake Jesup sometimes have so many gators eyes at night that you’d think you could cartoon run 13 miles across it and not have to touch water.
<3 is “less than three”, and 3 is “three” so logically < is “less than”
I try this, but I always get <3 mixed up with Ɛ>
aww love you too bro <3
Also < looks like an L at an angle
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!
Edit: thanks for the comments, it’s fascinating to get an insight on how differently people’s brains work. Something that seems like such an obvious concept is just as baffling to others as the crocodile is for me.
To attempt to explain it better though: Say the number you’re comparing to is 50. If x is less than that, say 30, then it would appear to the left of 50 in the list and the arrow would point that way <–. If it’s greater than 50 then it would be to the right -->
you say that but your method is only just as intuitive lol, wild how many methods work.
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.
Here’s a wild thought: inequalities are not always written with the lower number on the left… or there wouldn’t be a need for two symbols.
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 >
wow that’s a big difference (I have no idea what you are talking about)
It is just a notation for linear algebra and linear operators on complex vector spaces together with their dual space both in the finite-dimensional and infinite-dimensional case. Really quite simple stuff actually…
smiles and nods, smiles and nods…
I think 〉 means a very hungry (or at least large mouthed) crocodile, and > is just a normal one.
No? Not everyone’s doing work on quantum systems. Far from it. Most people do not need to use Dirac notation.
I guess not. Its just that when I hear ‘theoretical physics’ I immediately think of particle physics (and related fields). I have this idea that in most branches of physics people just say the topic, eg. astronomy, material sciences, or whatever; and don’t usually specify whether they are doing theoretical work or experimental/empirical work. But in particle physics … my impression is that people are more likely to specify. Anyway, that’s just my own bias I guess.
I earned it as the larger part being on the side of the bigger number

What the bird beak pecks is meek.
I see nothing wrong with this.
