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…
“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.
Crocodile? Are you guys from Florida? In Europe we learned it as duck beak, it just makes much more sense, where are the teeth? Nowhere it’s not an alligator mouth it’s a beak
Duck, crocodile, they’re both archosaurs. Which means if it’s either, they should have a premaxillar fenestra on the lower jaw, but I’m not seeing any. Clearly, this must be a possum.
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.
Somehow, people don’t teach this interpretation at schools. (Despite it being so obvious that it was clearly the original reasoning behind the symbols.) And then nobody talks about the fact that nobody knows how to read them, forever.
Mine had something about crossing a line through the symbol and seeing if it makes a 4 or a 7. Honestly, “the crocodile wants to eat the big number” is still better than this.
This is only tangentially related but I’ve noticed an increase in people saying backslash instead of slash when speaking an internet address aloud. I think many more people struggle with / vs \ than > vs <.
I remember it because I’m old and was into computers before the internet. Local drive was backslash "" as a directory separator and online it was slash “/”.
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.
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 also think the “etymology” of the boolean symbols is very helpful in remembering which is which. in lattice theory, their use was inspired by similar notation in set theory. so, A ∨ B is like A ∪ B, while A ∧ B is like A ∩ B.
generally, A ∨ B is “the smallest thing that’s greater than or equal to both A and B”, while A ∧ B is “the biggest thing that’s less than or equal to both A and B”. similarly to how A ∪ B is “the smallest set that contains both A and B”, while A ∩ B is “the largest set that’s contained in both A and B”. you can also take things a step further by saying that in the context of sets, A ≤ B means A ⊆ B. doing this means that A ∨ B = A ∪ B, while A ∧ B = A ∩ B. and from this perspective, the “sharp-edged” symbols (<, ∧, ∨) are just a generalization of their “curvy” counterparts (⊂, ∩, ∪).
in the context of boolean algebra, you can set False < True, which at first may seem a bit arbitrary, but it agrees with the convention the that False = 0 and True = 1, and it also makes A ∨ B and A ∧ B have the same meanings as described above.
for some reason to remember ∩ and ∪ when I first learned it in school I visualized a mirrored symbol on top. the ∩ looked like a X which represented an intersection, while ∪ looked like an O which represented a whole. for English ∪ already looks like a U which can be thought of as short for union. that would’ve been easier.
ooh the mirror trick is quite handy. i don’t think i’ve heard that one before. i’ll keep that one in my back pocket in case i ever need it some day. i can’t remember exactly how i learned what they meant, but i think it was probably u for union and n for ntersection.
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 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…
Thinking of an alligator is more fun though.

Nope, it just sounds odd.
I’ll stick with big side = big number, small side = small number.
Crocodile? Are you guys from Florida? In Europe we learned it as duck beak, it just makes much more sense, where are the teeth? Nowhere it’s not an alligator mouth it’s a beak
Nono, we don’t do math in Florida anymore. Also we’d be more likely to use “alligator” (tho we have plenty of both)
A greedy crow is what they told me
Nah fam, if your bird looks like that it’s probably dead. I also learnt it as the crocodile in Germany

I’m thinking horribly mangled German bank executive with a lisp 🤷
In the pre-digital age when most of this was pencil markings, it was not uncommon to see someone had drawn the teeth in.
“It’s always pointing to the smaller number” is what my elementary teacher said 2<3

Just to note, backslash or forward slash refers to the side the slash falls to.
I remember it because I’m old and was into computers before the internet. Local drive was backslash "" as a directory separator and online it was slash “/”.
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?
That would be a pair of scissors, on its way to cut the number 1.
I’m with you, the croc is an opportunist and will eat the smaller, easier prey.
No, since it’s bigger it stretches the lines apart :)
I agree. It’s totally simple and people overcomplicate.

for English the AND sign looks like an A anyway. if you remember that for AND the OR is just the opposite.

Are you a programmer? I’ve never struggled with them either, but I’ve had a lot of exposure to them due to programming since I was like 11
