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!

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

To the tune of "Pop Goes the Weasel"

X equals the opposite of B Plus or minus square root B squared minus 4 A C All over 2 A!

Wow. Your school hated you if you didn't learn about the alligator or crocodile.

[–] FlihpFlorp@piefed.zip 4 points 1 month ago

Not even a mention of the duck!

[–] wiccan2@lemmy.world 10 points 1 month ago (1 children)

The version I was taught starts with the equals sign. There is nothing simpler to depict the concept of equality than two parallel lines of the same length. Now pinch one side to spoil the equalness, the pinched side points to the smaller number in the unequal pair.

[–] ColeSloth@discuss.tchncs.de 5 points 1 month ago

That's so much more work than just remembering the gator wants to eat more.

[–] lugal@lemmy.dbzer0.com 3 points 1 month ago

I'm so sorry for you that you didn't have a childhood

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

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

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?

[–] HyonoKo@lemmy.ml 4 points 1 month ago

She just wants to say she is writing a PhD thesis in theoretical physics.

[–] Soleos@lemmy.world 4 points 1 month ago

Because the arrow always points to the bigger number, silly. /S

I remember learning about these in first grade and the explanation we got was "the beak of the little chick is pointing towards the bigger number" and I can't stress how much more confusing an explaination that is compared to the crocodile. Picture the following scene:

 O>
\0/
/ \

Yes that's a bird shut up. Observe the beak. Where is it pointing in this case? That's right, it's pointing the wrong way. Why did they choose this stupid explaination? Who knooooows

[–] Stamets@lemmy.world 13 points 1 month ago* (last edited 1 month ago) (1 children)

What in the fuck kind of backwards ass logic is that?! CROCO GO NOM NOM ON BIGGY NUMBER BECAUSE HE HUNGY! What is wrong with your teacher, my god

[–] KoboldCoterie@pawb.social 15 points 1 month ago (2 children)

Pretty sure they were going for this, not a baby bird just standing there:

[–] Cruxifux@feddit.nl 6 points 1 month ago

Oh I understand what they were going for, not the issue I have though haha

[–] halvar@lemy.lol 2 points 1 month ago

yes as it turned out in about 10 minutes, but the picture she was trying to paint wasn't very clear to me until then

[–] SaharaMaleikuhm@feddit.org 21 points 1 month 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.

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

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

[–] Honytawk@feddit.nl 6 points 1 month 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?

[–] DarrinBrunner@lemmy.world 3 points 1 month ago* (last edited 1 month ago)

YES!

Read left to right, they make perfect sense:

Less than is <

Greater than is >

They all make visual sense:

=

±

<

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

[–] WhiskyTangoFoxtrot@lemmy.world 12 points 1 month ago (2 children)

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

[–] rustydrd@sh.itjust.works 7 points 1 month ago (4 children)

Sounds like a less fun version of the same rule.

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

[–] slysmy@lemmy.world 9 points 1 month ago

in other words:

[–] samus12345@sh.itjust.works 9 points 1 month ago

How childish!

It's obviously Pac-Man.

[–] artifex@piefed.social 8 points 1 month ago (1 children)

I learned "L" for Less than

[–] lugal@lemmy.dbzer0.com 6 points 1 month ago (4 children)

And Г is for greater than?

I feel this deeply as a 30 year old that has to repeat in my head "Never Eat Soggy Waffles" every time I use a cardinal direction

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

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.

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 1 month ago (1 children)

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

[–] mrgoosmoos@lemmy.ca 3 points 1 month ago (1 children)

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

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"

[–] WilloftheWest@feddit.uk 4 points 1 month 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.

[–] porous_grey_matter@lemmy.ml 4 points 1 month ago* (last edited 1 month ago) (2 children)

I am also an idiot who needs mnemonics to remember incredibly basic stuff. In a similar vein to OOP, I did a PhD in chemistry with substantial involvement with chiral structures and still don't really know left from right... but I never understood this one. Smaller number on the small side, bigger number on the big side always seemed really intuitive.

Also in a theoretical physics context I think of those symbols as Dirac notation more often than inequalities, but then I'm not a physicist.

I always think that less than 3 makes a heart <3

And "three larger than" makes a funny-looking face or a sexy bikini. 3>

[–] NigelFrobisher@aussie.zone 2 points 1 month ago* (last edited 1 month ago) (1 children)

Do they teach this in Primary School now? I’d have thought it was still addition, subtraction, timetables, long division etc; I first encountered these symbols learning BASIC at home.
