A meme that is actually a good math problem

you cant multiply on add

9+10-9+10-9+10=21

x = 10
y = 9

This can't be serious... literally do it with physical stuff like in preschool or something. You have 10 pennies and add 9 more. Is it 21 pennies? OF COURSE NOT

From my understanding, this math problem was created by rapper 21 Savage

Um, yeah. There is no way to make this work. Nine and ten are real numbers that represent real things. Numbers aren't just numbers for the sake of being numbers... they count things.

1+1=2 isn't some theoretical puzzle... 1 apple added to another apple equals 2 apples. You can't factor that away.

9 apples plus 10 apples wiill never equal 21 apples.

He’s not a genius @theprotecter995 or should I say sus😂😂😂😂😂📮

So I spent some time thinking about the problem for the sake of fuckery, and the starting process was the same, I also came to the suspicion that was in base 9. But I didn't feel like proving it.
Oh well. I'll have other puzzles to solve.

No.

i told chatGPT that "9+10" is in base X, and "21" is in base Y, and i will quote exactly what it said. "If we assume that 9 is in base 2 (binary) and 10 is also in base 2, and we add them together in base 2, we get:

1001 (binary for 9)
+ 1010 (binary for 10)
-------
10011 (binary for 19)

So in this context, 9+10 is equal to 19 in base 2.

However, if we assume that 9+1 is in base 2 and equals 21 in base 10, and we add 9+10 in base 2, we get:

1001 (binary for 9)
+ 1010 (binary for 10)
-------
10111 (binary for 23)
So in this specific context, 9+10 is equal to 23 in base 2." no joke.

x=ten and y=nine is an obvious solution
Assuming x and y are integers:
x≥ten otherwise 9 isn't a valid number
We can rewrite the equation as x+9=2y+1 which gives us x=2(y-4) or y=½x+4

once i saw someone's proof of this be:
9+10
if you add 2
19 + 2 = 21
therefore 9 + 10 = 21

MATH TEACHER IN OHIO💀💀💀💀

9 + 10 = 21
IX + X = IXX .. and get a mirror out .. XXI

10+9=19

9+10=21

Before seeing the answer I'll just say that 21 is base 9

FOLLOW MEE

oh yeah what's 21-10

That's not how adding works..-

addition doesn't work like that

Yes 9 + 10 is 21 yes good job okay

I thank the Indians.

Woooow verrry dangerous 😱😱😱😱😱

9 + 10 = 19

1+1 =69

SO MANY TEXT

Wala akong naintindihan hahaha

but y?

9 + 10 is 19

Bruh 9+10 is 19

I always thought the kid say “eñiwan"

Given that there is an infinite number of answers to make x and y true wouldn't that mean that the numerical system is fallible and completely irrelevant?

base 9

Kuy

Stov shoving in cow lover propaganda in everything. It's called the arabic numerals cause Arabs came up with it.

BRO CHILL ITS JUST A MEME

Ok but if you don't add extra stuff and just do 9+10. It equals 19

try to apply that when counting thousands of dollars. 9k + 10k is 21k right?

Nothing like coming up with a theory to fit the answer you need but in the real world how is this of any use?

bruh it is 21 if you dont think so you are just flexing that you are good at math

I give you 19 apples. You must add two more apples without actually having any apples available. Not real, like this equation. Irrelevance

Irrelevant.

This is called finding a solution to a problem that does not exist. Using a bunch of mumbo jumbo, I can prove that 10 + 9 = orange.

DUDE IT IS 19!

Nah nah it’s not.
9+10? You gotta count
I’ll use emojis for example
❤❤❤❤❤❤❤❤❤❤these are 10 hearts
Now count until you get 9 on yo fingers
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
If u don’t get it get a calculator and also it’s 19 not 21

I wish I was in kindergarten so I could answer 9+10 as 21

Sounds like entitled millennials trying to rewrite the entire world
