ひ、ふ、み... are the forms of numerals you use when counting on fingers. It's pretty much the only time you use the base, unadorned forms of Japanese (as opposed to the Chinese ones) numbers.

Oh god, she even handles math in base 9...

...wait...Who the hell uses base 9 anyway?

...Great part is that once you accept it as base 9, they are all right.

Haha, that's awesome! (And yes, I double-checked them, they all do appear to be correct in base 9.)

Playing with unusual number bases is fun. Kinda reminds me of H2G2, where they found out the ultimate question was "what do you get when you multiply 6 by 9", then some fan found out 6x9=42 in base 13 (though Adams claimed it was unintentional).

Huh. I did not know that. I thought it was just an IOSYS reference.

Yeah. "hi" as in "hitotsu", "fu" as in "futatsu", "mi" as in "mitsu", etc.

Wait, if she's counting in base 9, then is she actually a genius?

Genius, perhaps, but at least it shows she can do maths in base-9.

Maybe she hates being 9 so much, she does it in base-9 so it's impossible to get 9 as an answer?

uh... Maybe my just math sucks: Can comeone explain what's this 9-base? I mean, I can understand the joke, but I can't do the operations with 9's... Well, i can, but not same result :/ (English is NOT my first language, so my mathematical vocabulary is a bit weak)

base nine is just using a different way of counting. we use Base 10 because we have 10 fingers, the 2nd place being the number of full sets of digits. base nine would be based on 9 digits total, so 10 base 9 = 9 base 10, 20 base 9 = 18 base 10, and so on and so forth

if you're familiar with hexadecimal, it's a similar concept. Hexadecimal is base 16 (and is usually notated in programming by the special designation of 0x before the number so I'll use it here). 0x10 = 16 base 10, 0x1A = 26, so on and so forth

in summary, for base 9 math, the ones digit is the remainder, the tens digit is 9^1, the hundreds digit is 9^2, and so on and so forth

She still fails on half of the problems, though.

No she doesn't...

How strange that it seems easier than base 10 to me.

I'M THE SMARTEST.

42-5=37, 8*12=96, and 25+36=61.
If she is using base 9, then her answers, 36, 107, and 62 would be 33, 88, and 56 in decimal. And, hopefully, you can see that 37!=33, 96!=88, and 61!=56, with "!=" meaning "does not equal".
Hence, she still fails on half of the problems.

25+36 = 62. Hmm.

6 + 5 = 6, 7, 8, 0, 1, 2. So yep, That's a 2 in 1s column...

2 + 3 = 5 nines... Carry the 9. 6

62?

Ah.
The operands are also in base 9.
Nevermind, then.

Perhaps you missed my debate on perceived recoil using relativistic projectiles vs non-relativistic anti-matter beam weapons in the Touhou universe?

Well, I saw it, but I didn't read through it... ^^;
But, honestly, I should have considered the possibility that the operands were in base 9.
I fail.

The ancient babylonian used the base of 16 and did really well...so everything is a matter of perspetive

The answer is 42 all problems solved. Have a nice day. ^^

Uh... that's base-60. Why they chose 60, however, is still left to debate. Either because it's a multiple of quite a lot of numbers (1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60); it's 10 (the fingers, duh) multiplied by 6 (sides of a hexagon; curiously, if you connect opposite edges of a hexagon, the radius from center to edge is the same as the length of each side; perhaps related with their invention of the wheel?); or it's something related to the stars (or so I read from some strange book).

Anyway, I think this should go in the clever pool... though I don't know how it's done.

I think 61!=67, 37!=41,96!=116 in base 9 ;)

You are wrong. Her answers are also base 9, all of the math is correct.

She's using base 9 on the operands as well. When converted to decimal or base 10, all these equations will look like this...
> 42(b9) - 5(b9) = 38 - 5
> 8(b9) * 12(b9) = 8 * 11
> 25(b9) + 36(b9) = 23 + 33

Once converted to decimal, solve normally...
> 38 - 5 = 33
> 8 * 11 = 88
> 23 + 33 = 56

Now that we have the answers in decimal, convert these to base 9 to conform with the radix used on the original equations...
> 33 = 36(b9)
> 88 = 107(b9)
> 56 = 62(b9)

Then, pair the answers to their respective equations...
> 42(b9) - 5(b9) = 36(b9)
> 8(b9) * 12(b9) = 107(b9)
> 25(b9) + 36(b9) = 62(b9)

Hmm... Does anyone else think otherwise?

Well, thank you three for telling me something that I already figured out a month ago. Especially after I had made a statement to that effect. Namely:

Apparently saying that you have failed in your argument doesn't keep other people from saying that.

Oh... Well, never mind...
In any case, I still find this too clever for Cirno...

In short, Cirno is not an idiot, she just perceives the universe in base 9, making it appear as though she is not as smart as she really is.

Oh danbooru. You never fail to amaze me with the kind of company you keep.

I came back in here and I was all 'wtf, we already had this argument.'

Cirno is a genius.
Doesn't need to conform to the universe, anything can happen in gensokyo!

I come here expecting jokes, and YOU PEOPLE have to go and break ma brains.

Bravo, danbooru, bravo.

Eye believe Cirno is the smartest.

It seems easier to just do the work in base 9 instead of converting to base 10, doing the work, then converting back, at least for the addition/subtraction.

Great.
Now I feel paranoid for checking on this post almost every day for the last month to see if anyone else tries to correct me...
