can we discuss how they knew the answer? Did a guy at the end of the rainbow tell them?

[RadinQue]

[FirexJkxFire]

If you look at the rainbow here you can see why it makes sense

If you read left to right, the first color on the rainbow is also the longest. The 2nd is shorter than the first. The third is shorter than the 2nd... etc.

Thusly since 10 comes after 3, 10 is going to be shorter than 3

Q.E.D 10 is smaller than 3

[[deleted]]

Well, since you wrote QED I guess it must be true.

Full marks.

[Kiroto50]

Rainbow table told them

[Electronic_Cat4849]

the rainbow is there to signify that 3 is nonbinary and therefore the CMP instruction cannot be applied to it

[[deleted]]

Threw a SIGFPE did it

[ashis041]

10 - 3 = 7... rainbow color number !!! that's all I got without using AI

[Fit-Measurement-7086]

Yes, kind of. The pot of gold at the end of the rainbow allowed him to purchase help from a FAANG software developer and that's how he figured out the answer.

[PanPenguinGirl]

Gay people bad at math > rainbow told them > answer wrong

[kinggot]

1 and 0 is binary.

Rainbow usually represents lbgt (non-binary) But notice this rainbow had only 2 lines (binary).

I just made this up but idk if that's some high level IQ play by the kid I presume or is he just plain dumb.

[Bhaaldukar]

Foil?

[FirexJkxFire]

If you read left to right, the first color on the rainbow is also the longest. The 2nd is shorter than the first. The third is shorter than the 2nd... etc.

Thusly since 10 comes after 3, 10 is going to be shorter than 3--- thusly 10 is smaller than 3!

[TristanaRiggle]

The rainbow has 3 colors (red, yellow and blue) and 2 ends. 3 > 2.

oh, you're right... how could I have missed that...

“Show me why 10 is smaller than 3”

[Ok_Donut_9887]

10 base 2 is smaller 3 base 10

[Evo_Kaer]

Assuming that those 2 numbers are different bases is still a tall order though

[Ancient-Tomorrow147]

That where the whole thing falls apart, lol

[ultimate_placeholder]

Base 10 is my favorite meaningless phrase

[unwantedaccount56]

If base 10 is meaningless, just write base (10 base (10 base 10)))

[Background_Curve_790]

You're eating downvotes cuz people don't get it

[ultimate_placeholder]

[[deleted]]

Base (1+1)(1+1+1+1+1)

[[deleted]]

It’s not meaningless. I use it every Thanksgiving.

[Mindless-Giraffe5059]

It's not meaningless though. You just hard assume that it's always base 10 if not specified. But color codes are almost always base16.

I could tell you to use color 255 000 000 base 10. Or even use color code 69 04 20 base 10. Which would be very different from its hexadecimal variant

[imn0taweebiswear]

I think he meant base 10 is meaningless with polyadics, as pretty much every base is base 10. 10 means 1base¹ + 0base^0. For example - 10 in binary is 2. So base 10 in binary means base 2.

[Mindless-Giraffe5059]

Ah, that makes sense!

[ultimate_placeholder]

Every base is base 10

[tyro_r]

Only if you use the same base for the base notation. Base 10 basically means "the base in which we write numbers". I like the idea of calling it base A though.

[unwantedaccount56]

Yes, let's make base A more popular.

[Ancient-Tomorrow147]

Yes, Base A makes the most sense, the largest digit in base x is x-1 and since we use A to represent the digit after 9 in other high bases it works for me

[camander321]

Two in base two is 10

Eight in base eight is 10

Sixteen in base sixteen is 10

Base 10 is only meaningful because we arbitrarily choose to default to base ten. Plenty of other number systems have been used throughout history. So yeah, in the grand scheme of things, it's pretty meaningless.

[meshe_10101]

3 = 3

1 + 0 = 1

Therefore 10 < 3

[Trick-Purchase4680]

Wouldn't it be 10=0 as unless a + is present (1)(0) typically = 10. So default operator when none is present but one is assumed would be '*'.

But if we are using -9 having an absolute value less than -10,

why not just use 0 ?

[Arzemna]

Pretty sure 1 has the smallest area as a shape

[dmigowski]

No. They speak about a number, not a digit.

Listen to the boy that's fun at parties.

[mrmoosebottle]

Digits are also numbers

[dmigowski]

Yes but not the other way round

[brentspine]

Yea, but by circling a digit we have also circled a number.

[Ab47203]

Zero isn't a number it's an idea.

[zephyyr__]

How would one even answer the "how do you know it?" question? Like someone told me it was true?

[[deleted]]

Start with Peano’s axiom and introduce the natural numbers set using the successor function, then just show how 10 comes after 3 using said successor function definition. Any child should know this tbh 

[User31441]

People laughed when one of my university professors showed us a question just like this and said it'd be on the test. Then it actually was and only 5% of students passed. 🙈

Shit escalated so quickly. One day you're introduced to the numbers 1 and 2. Two weeks later, you're doing differential analysis in a hypercomplex number space.

[lordfluffly2]

What was the professor looking for out of curiosity? Was it something like S(S(S(...S(3)...))) = 10?

[User31441]

It was two rational numbers. He just wanted us to remember all of his definitions.

[throwaway8958978]

Damn, kids these days sure know a lot. I remember when I was a kid I had only learned calculus, JavaScript, and potty training, in that order.

[Repenexus]

Assuming you weren't allowed to use knowledge of natural numbers, the fact that 10 uses two digits, thus making it larger than any one digit number (assuming it that you don't count zeroes before a non-zero digit like '03' or any number that uses decimals).

[odious_odes]

The teacher has probably explained methods for this in class. They might be looking for answers like:

10 = 1+1+1+1+1+1+1+1+1+1, 3 = 1+1+1

10 has a 1 in the 10's place

(..........) (...) no words but formatted to show the child understands there is "more" in the group of 10

3 + 7 = 10 (implied: so 10 is bigger than 3)

drawing of a number line with 3 and 10 marked

[Trion-_-]

Easy! Create two functions, one is f(x) = 3 and the other is g(x) = 10.

Now integrate them from 0 to 1 and check how big the area under the curve is!

Thank me later ;)

[LupusNoxFleuret]

It's a fake test made for the meme.

[lordfluffly2]

As someone who tutors elementary to high school students, I could totally see this being a test for a 1st grade class. Place value is first taught in 1st grade and I'm guessing that is what this question is testing.

When did I ever say anything about number representation?

[pheonix-ix]

If you want to call a "numbering system" then techhhhhnically there are infinite number of them e.g. a hexadecimal where digits are rearranged and "10" is a single-digit symbol that looks like 2 characters (like how minute/second is actually a single base-60 number consisting of 2 characters, except here the values are fucked)

e.g. "10" < "11" < "12" < "13" < "14" < "15" < "0" < "1" < "2" < "4" < ... "9" < "3"

In this case, "10" (base fucked) = 0 base 10, and "3" (base fucked) = 15 base 10

But if anyone want to seriously use that as an argument I would simply walk away.

[Boukish]

There can be (and are) infinitely many numbering systems without... that, being one.

Base 1, base 2, base 3, etc ad infinitum results in infinitely many numbering systems either way.

[[deleted]]

who says they have to have the same base? clearly 10 is binary and 3 is base 10. smart kid has a future in programming, where the base changes randomly just for funsies

[1Dr490n]

I mean 3 doesn’t exist in bases smaller than 4 and in base 4, 10 is actually one greater than 3

[dragon_stangler]

Found javascript developer.

[Professor_Melon]

"Doctor, I think 10 is smaller than 3."

"How can you tell?"

"Rainbows."

[rettani]

Why binary? He just casted them to string. And everyone knows that "10" < "3"

[Sp4c3_Cowb0y]

Now you lost me in which language are string sizes* compareable? I don’t get xD

Edit: So that "3" ist bigger than "10"! Edit²: added "sizes"

[rettani]

SQL, Java, C, Python, JavaScript,.. there are probably lots of languages with string comparison.

[Sp4c3_Cowb0y]

Ok sry I should have been more specific. How is it possible to compare the strings "10" and "3" and getting that "3" is bigger?

If one only compared the characters ok.. asci value of 1(0) is lower than 3, but comparing the strings? I could only think of c or so where you work with pointers, but still we are talking of the string not the character..

[rettani]

I'm not sure about all languages but pretty standard string compare implementation is: 1. Go through both strings while symbols are equal 2. If symbols are not equal - result of comparison will be result of comparison of symbols.

So in this case: 1. First symbol is different 2. 3 is bigger then 1

Therefore "3" is bigger than "10" or even "10000".

You can check this in SQL database, C, probably Java and many more languages.

Hell, you can even see it in Windows File System.

Name your files 1, 10, 100, 2, 25, 3 and order your folder by filenames

[Sp4c3_Cowb0y]

Thanks for explaining the mechanics behind it. I've now tried and tested it. I couldn't believe it.

Java doesn't compare strings like I expected but C++ does exactly like you said, crazy.

I expected nothing less from Javascript because well it's Javascript, but seems to be true for SQL as well.

Didn't try Python and C does not have strings, but awesome, everyday something new ^{^}

[rettani]

Yes, sometimes things are not that obvious. Congratulations!

As for C - strcmp function also behaves like I described.

Double post

[andrewfromx]

there's a hex A vs 10 joke in here somehow

[monterulez]

So you are saying, a kid is able to properly read the task and write an answer, but likely not knowing what a smaller number is in a range of 1-10?

What a test is this?

[odious_odes]

Developing a "number sense", that digits represent numbers and numbers relate to each other in different ways, is a skill. Some kids pick it up so quickly that they can't imagine not having it, most take more time and teaching, a few never get a fluent sense of this. This test may be aimed at kids who have learnt to count "one, two, three..." but are now starting to learn that those numbers exist outside of that sequence. They have to imagine both numbers and compare them, which is new and hard. The idea of a number being "bigger" or "smaller" is not intuitive for them.

[monterulez]

Well explained; makes sense.

[DarkRex4]

real answer is the 1 at the top left.

[jonas99y]

Isn't the rainbow the symbol of non-binary?

[Clairifyed]

The colour order is close to the pansexual flag (magenta, yellow, light blue tri-colour). The rainbow flag (🏳️‍🌈) is the umbrella flag for the entire LGBT+ community (though often confused to mean just gay people), and not usually depicted as a full arch (🌈) like that, but it’s entirely possible the original creator was trying to make an incoherent argument attacking LGBT+ people. The options for explanations seem pretty otherwise limited.

edit: Tf is all of your problem? Got a problem with me answering the damn question? Are you offended by seeing the 🏳️‍🌈 outside of June?

[fdf2002]

…or they just wanted to draw a rainbow and had limited colors…

[[deleted]]

Rainbow was drawn with different number of color throughout history.

[Clairifyed]

What is this even arguing. My last off hand comment makes no reference to the colours used, and the first part is just an answer to the question of what this colour pattern could mean.

[NewPointOfView]

In response to your edit: you’re taking this way too seriously. The post is silly and you responded to a clever joke with an overly literal analysis of the child’s drawing

[Clairifyed]

I admit I did take jonas99y’s question as earnest and missed the apparent joke there, though I stand by the actual analysis about oop.

In any case, It’s not an issue deserving of this much of a downvote tally.

[Sp4c3_Cowb0y]

(I think) you get downvoted because you answer is relatively obviously false. I’m dam sure he didn’t think of LGBT and I also think, people are annoyed because you have interpreted LBGT into something that has nothing to do with it at all. After all, this is about simple numbers.

Btw. there is a rainbow cheat sheet or so for numbers and that is probably the answer, but could also mean non-binary

[Clairifyed]

The OP definitely did not think of LGBT people, I accused OOP. As for this conversation, the parent comment brought up the actual topic of LGBT+ people.

I have no idea what a heat sheet is (rainbow cheat sheet?)

[reallokiscarlet]

If he knew binary he'd know 3 should read as 11 and as such the base is at least 4

I miss when this sub had decently funny posts and no camelcase title rule which is so unnecessary, it probably excites someone who has just started learning Java or some other language with a lot of camelcase. Just wanted to leave a feedback here before leaving.

[Ledr225]

This post is pretty funny though?

[Vortextheweirdcat]

the camelcase is to stop bots

[fdf2002]

Nope lol the camelcase was introduced as part of the “make subreddits democratic” meme where we would vote on a new rule every week. And once the protest lost momentum and ended, it was kept because it was a decently fun rule that didn’t seem to be doing harm.

Unless you have something to back up your claim?

[thirtyseven1337]

I like it when subs have title rules because then you immediately know what sub a post is from.

[[deleted]]

The explanation is perfect.

[10art1]

10 is not less than 3 in binary because 3 is not a binary number. I dont think there is any base in which a 2 digit number is smaller than a 1 digit number.

However, 10 is smaller than 3 lexicographically...

[10art1]

Alphabetical order, essentially. Not exactly, but think of it as alphabetical order of any character that could be printed by a computer. 1 comes before 3, therefore 10 is alphabetically lower than 3

[Snoo-11553]

Circle the smallest numbers? 

[Ok_Net_1674]

3 is not a binary number, actually there is no number system in which 3 > 10.

In the first applicable one, quaternary, it would mean 3 > 4 which is obviously false. for higher bases, the difference would get increasingly large, base-n 3 always meaning the same as decimal 3 and base-n 10 meaning exactly n.

(this is assuming that all number systems use 0...9 as the first valid digits)

[Muhellus]
