He i’s smart

[–] ceenote@lemmy.world 21 points 2 days ago (1 children)

If a smart person said it, maybe that's how it's supposed to be spelled. What are your credentials to dispute it?

[–] lugal@sopuli.xyz 8 points 2 days ago

I a'm also smart and I can confirm that i'ts correct

[–] Darkard@lemmy.world 9 points 2 days ago

How can we with that big red circle around it.

Low-tech typo.

[–] X@piefed.world 6 points 2 days ago

I’m moderately impressed that they used punctuation at all, I’ll let it slide

[–] saimen@feddit.org 4 points 2 days ago (1 children)

How do you know I a'm is incorrect?

[–] snooggums@piefed.world 4 points 2 days ago

Because I'am smart!

[–] Etterra@discuss.online 3 points 1 day ago

Because I could eat 20 cookies, but 40 is too many. And that's terrible.

[–] wizardbeard@lemmy.dbzer0.com 69 points 2 days ago (4 children)

God I hated questions like this in school. There's always something specific the teacher is looking for, but nothing to point you towards it.

[–] nymnympseudonym@piefed.social 19 points 2 days ago

Usually the pointer is the blahblah the teacher was droning while you were fantasizing about the attractive classmate sitting directly in front of you

[–] ThatGuy46475@lemmy.world 9 points 2 days ago

I suppose “by definition” would probably have been counted as wrong

[–] GraniteM@lemmy.world 8 points 2 days ago (1 children)

I'm thinking maybe "Because if you subtract 40 from my number you get a negative number," but I could be either over- or under-thinking it.

[–] scibra122@piefed.social 4 points 1 day ago (1 children)

I was guessing either it has fewer digits or the tens digit is less than 4 would be the desired answers depending on what the selected number was, that kind of question feels like it would predate negative numbers on the learning curve

"Because it has less in it"

[–] grue@lemmy.world 3 points 1 day ago (1 children)

Yeah, I always felt like I was either pointlessly restating the obvious or it expected me to derive the damn thing from first principles.

AI slop proof, just because I was curious if duck.ai could do it

Using the natural numbers defined from 0 by the successor operation S:

1=S(0), 2=S(1), ... , 20=S^20^(0), 40=S^40^(0)

Define a < b to mean that there exists a natural number k such that

a+k=b.

Take a=20 and k=20. By repeated addition,

20+20=40.

Since 20 is a natural number, there exists a natural number k such that

20+k=40.

Therefore, by the definition of the ordering relation,

20<40.

(Is it correct? Fuck if I know!)

[–] Zarobi@aussie.zone 5 points 1 day ago

A.I. is proving that 20<40 by:

  • creating a sequence
  • then completely disregarding that
  • then saying that since you can add 20 to itself to create 40 it must be less
  • then disregarding that and saying that the sequence of numbers proves it because we found 20 first

Honestly since it's such a simple equation, in real life you could just say 20<40 because 20<40. You don't really need to prove anything, the proof is in the logical operator. The homework question is dumb because it isn't clear what they're asking for.

[–] 9gagescapee@altgag.net 2 points 1 day ago

I a'm smart t o'o!

[–] kubica@fedia.io 40 points 2 days ago (1 children)

Because that's how numbers work, duh.

[–] PointlessLifePersonified@slrpnk.net 11 points 2 days ago (1 children)

Arbitrary glyphs can mean whatever we decide they mean. One day 8 could mean what we commonly consider to be 2 today - we just have to choose for it to be so.

[–] Chef@sh.itjust.works 12 points 2 days ago

Reality by agreement.

[–] bjoern_tantau@swg-empire.de 24 points 2 days ago (2 children)

What's the expected answer? "Because 2 is less than 4"? Could be "because 20 + 20 = 40" but that seems to be too advanced for these types of tests.

[–] NeatNit@discuss.tchncs.de 25 points 2 days ago (1 children)

The question is intended to create an existential crisis and gaslight the pupils. How can anyone truly know anything?

[–] nymnympseudonym@piefed.social 4 points 2 days ago

Seriously this question can only be properly answered with Russel & Whitehead

[–] Hazel@piefed.blahaj.zone 10 points 2 days ago (2 children)

Probably a number line? Draw a line to show it's only 2 jumps to 20 but 4 equally spaced jumps to 40.

As a teacher that's what I would've done at least. Number lines are quite effective at helping kids visualize numbers.

This response doesn't seem to indicate this particular teacher has adequately explained what the expected answer is though.

[–] RidderSport@feddit.org 3 points 2 days ago (1 children)

Sounds reasonable, but the task should be something like "Draw a graph and show why 20 is smaller than 40" or something

[–] Hazel@piefed.blahaj.zone 2 points 2 days ago (1 children)

Eh, I don't necessarily agree, you're testing a child's ability to come up with a solution moreso than their ability to follow instructions. Other answers are possible, and maybe a student prefers their own way. But one way of doing it, like a number line, should be so ingrained in all students that anyone knows at least that one way of doing it, imo.

[–] lugal@sopuli.xyz 1 points 2 days ago

I don't think so. The question is so vague that I wouldn't know what to say and be stressed out. For a class room setting where everyone can share their idea it would be a different story but not in a test

[–] StumblingWasabi@lemmy.today 1 points 1 day ago

Should've been "use this number line to show why" or something to that extent

[–] DigDoug@lemmy.world 10 points 2 days ago (1 children)

The teacher is probably looking for something like "Because 40-20 is positive".

[–] snooggums@piefed.world 8 points 2 days ago (1 children)

"Because 20 - 40 is negative."

[–] Jankatarch@lemmy.world 7 points 2 days ago (2 children)

"Because ln(20/40) is negative."

[–] Gonzako@lemmy.world 5 points 2 days ago

"Because with 20 cranks you can't do 40 hogs"

[–] StumblingWasabi@lemmy.today 4 points 1 day ago

Because the set of numbers including 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 contains a greater amount of numbers than the set of numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40

[–] DarrinBrunner@lemmy.world 10 points 2 days ago

"Because I paid attention to my teacher."

That should do it.

[–] crozilla@lemmy.world 10 points 2 days ago

Lazy quiz questions were the bane of my education.

[–] tyler@programming.dev 5 points 2 days ago

This has to be the most useless red circle I’ve ever seen.

[–] OwOarchist@pawb.social 4 points 2 days ago

"I asked ChatGPT, and it said so."

I was soooo expecting a picture of Trump under that post title.
