When I taught math to young students I used alligators.......Muh haa/0/

****I'm leaving the random characters that have been added to my evil laugh. They were added by Zip the orange 3 month old terror kitten

[–] WilloftheWest@feddit.uk 3 points 4 hours ago

I saw the angles and assumed this was a joke about Dirac notation, which I'm still convinced is a massive joke to get mathematical physicists seriously talking about bras and ket in the staff room.

[–] Gustephan@lemmy.world 4 points 6 hours ago

I just use both with a footnote that reads "one of these symbols always lies, one tells the truth. Determining which is which left as an exercise for the reader"

[–] Corkyskog@sh.itjust.works 4 points 6 hours ago (2 children)

I know someone who did their entire thesis purposely without using effect/affect, because they didn't know the difference. Instead used "impact" and other similar words.

[–] mister_flibble@sh.itjust.works 3 points 5 hours ago (1 children)

Affect is an action and effect just exists is how I always remembered it.

[–] mrgoosmoos@lemmy.ca 3 points 5 hours ago

that's a lot better than my method of remembering that effect is not a verb

[–] rmuk@feddit.uk 1 points 6 hours ago

I can only imagine the impact that had on the end result's impact. Probably didn't have the impact they wanted on the readers who were unimpacted by the message.

[–] astagahdragonz@lemmy.world 1 points 4 hours ago

Most Indonesian school teach to use use it like l> "besar" and l< "kecil". Besar = big, kecil = small

I still think "Pervert Naruto" for PV=nRT

[–] Alenalda@lemmy.world 2 points 6 hours ago (3 children)

I have to read random passwords to people, nobody knows which is the greater (>) and less (<) than symbol.

[–] Korhaka@sopuli.xyz 2 points 5 hours ago (1 children)

Because they are all just knowing it points to the bigger number. >100 and 100< are interchangeable.

[–] SLVRDRGN@lemmy.world 2 points 4 hours ago (1 children)

uhh... doesn't it point to the smaller number?

[–] Korhaka@sopuli.xyz 1 points 4 hours ago

I guess it depends how you view it pointing, the wider side is directed to the larger number

[–] kopasz7@sh.itjust.works 2 points 6 hours ago

When I encounter this, I have to imagine a context as I would read it. eg. X > Y as X is greater than Y. Because <> are just angle brackets to me.

[–] trk@aussie.zone 1 points 6 hours ago

The greedy bird eats the biggest number

lots of food > not much food

[–] SaharaMaleikuhm@feddit.org 19 points 12 hours ago (2 children)

big > small
as in the symbol is big and open on one side and small and closed on the other. It could not possibly be more literal than that.

[–] DarrinBrunner@lemmy.world 2 points 5 hours ago* (last edited 5 hours ago)

YES!

Read left to right, they make perfect sense:

Less than is <

Greater than is >

They all make visual sense:

=

±

<

[–] drunkpostdisaster@lemmy.world 6 points 12 hours ago (1 children)

That was not how it was taught to my developing elementary brain.

[–] Honytawk@feddit.nl 5 points 8 hours ago

Sure, but if you regularly use it, wouldn't you think more about the symbol?

And wouldn't it make more sense to an adult brain to see one side wider and one side smaller and continue the line in order to understand which size is bigger?

[–] samus12345@sh.itjust.works 9 points 12 hours ago

How childish!

It's obviously Pac-Man.

[–] callouscomic@lemmy.zip 0 points 5 hours ago (1 children)

This never made sense. The larger animal would eat the smaller one.

[–] Korhaka@sopuli.xyz 1 points 5 hours ago

The crocodile wants to eat the larger child

[–] WhiskyTangoFoxtrot@lemmy.world 12 points 19 hours ago (2 children)

Why not just remember that the bigger side of the symbol points to the bigger number?

[–] kopasz7@sh.itjust.works 4 points 6 hours ago* (last edited 6 hours ago)

But the pointy end should be pointing. This phrasing could get confusing.

[–] rustydrd@sh.itjust.works 7 points 19 hours ago (1 children)

Sounds like a less fun version of the same rule.

[–] SaharaMaleikuhm@feddit.org 1 points 12 hours ago (3 children)

rule

Calling that a rule is weird. Like do you have a rule which side of the knife is used to cut? Which part of the toothbrush goes in your mouth? You don't? Right, cause it's entirely obvious.

[–] nyctre@lemmy.world 2 points 7 hours ago

It's more of a consensus, than a rule. It's only obvious because of the way we phrase it and the consensus to use that symbol. But we could've just as well settled on something like "x follows y" or whatever and you'd have an arrow pointing at the bigger number. Or any other number of ways to compare without using that symbol exactly. It's more a language than anything, really. What's important is that everyone understands the same thing regardless of what symbol we use. That's why everyone uses it like that, not because it's obvious.

Wait… was I the only one that got taught: small number on the small side, big number on the big side?

No cute little metaphor, just deal with the bleakness of the world, kids!

[–] lunarul@lemmy.world 1 points 3 hours ago

I was just taught this is the symbol for bigger than and this is the symbol for less than. And we remembered them the same way we remember the letters and the numbers and all the other symbols like addition and subtraction. No need to think about it, just "<" and "less than" are equivalent in my mind.

[–] sqgl@sh.itjust.works 3 points 6 hours ago (1 children)

I imagine that is how the symbol came to be used. I doubt they imagined crocodiles.

[–] WhiteOakBayou@lemmy.world 2 points 4 hours ago

When this symbol was formalized crocodiles were a much more persistent and immediate threat. They thought about them constantly.

[–] MnemonicBump@lemmy.dbzer0.com 28 points 1 day ago (5 children)

This is like when I found out everybody else got a cute little song to memorize the quadratic equation.

[–] PlexSheep@infosec.pub 2 points 6 hours ago (1 children)

In Germany, we have this. At least I think that quadratic formula means the ABC Formel? If not, I'm sure dorfuchs has a video for it too.

My favorite is the one for the bionische Formeln.

[–] MnemonicBump@lemmy.dbzer0.com 1 points 2 hours ago

That's much better than anything we have in the U.S.

Silly Old Harry caught a herring trawling off Anglesey.

[–] Decq@lemmy.world 29 points 1 day ago (6 children)

I really don't get why you would need a mnemonic for a symbol that itself already is a mnemonic? How could it ever be confusing that big side is bigger than small side?

[–] rmuk@feddit.uk 0 points 6 hours ago

Right? How hard is it to remember that it's an arrow that points at the biggest number? /s

My teacher said “Pac-Man wants to eat the number that gives him the highest score” and that sooo stuck with me

[–] Lemminary@lemmy.world 5 points 19 hours ago

I've always found it interesting that many people have a hard time remembering this. I feel like it's one of those self-describing symbols.

[–] nightlily@leminal.space 7 points 20 hours ago (1 children)

I used to even draw in the teeth.

[–] rmuk@feddit.uk 2 points 6 hours ago

I think I was fifteen when my maths teacher took me aside and told me my less-than symbol didn't need a plover bird.

[–] OhioComrade@lemmy.ml 2 points 15 hours ago

What made the symbols finally click for me is drawing a small number line with the arrows on either end and erasing the line.
