Math

Postby Christian_ » Mon 10.02.2006 6:59 pm

Well, today I was doing my Algebra homework and thought of a good idea. I know everyone uses arabic numerals now, (and I'm not a math junkie, I really don't like math) but would anyone be intrested in making up simple Algebra (Maybe just normal math?) questions using only Japanese characters? Then another person could slove them. If no one is intrested then just let the thread die I guess. Could anyone show me some where to learn to use numbers better too? I just thought this thread could help people, like me, who have neglected numbers.

Here's an example of what I was thinking:

一)四ーニ=?

Then the next person would answer and make a new problem. So what do you guys think?

....was one of those a minus sign?
the problem with math using kanji is the 一
you're better off using 壱
and even with that, the 二 and = can also be slightly confusing
I really have no clue what your question there says
it looks like
one close-parenthesis for minus two equals ?

Sorry if this is off topic, but this made me think of something else. Do the japanese use different symbols for things like integration (∫), or even logs or summations? I always assumed that these things were international but I don't have much of a basis to think it.

Oooo! I SO love Math! (note the sarcasm x3)
In Japanese, they don't use those chinese numbers that you learn anywhere else.
Such as 一 is one in Japanese = beep, beep! Wrong!
They actually, believe it or not, use English numbers (i.e. 1, 2, 3, 4,...) when writing them out, and pronounce each number in it's meaning in Japanese.
For example, 1 one be 「いち」, 2 would be 「に」etc.
ANYWAYS, for the Math, I think it's the same as how we do those stupid itsy bitsy equations out, except you pronounce each character, and the algebraic expression in Japanese. =3

So instead of any mathmatically written differences, does anyone know the terms used for symbols in japanese? I think that would be more useful for everyone interested.

I'm pretty confident Japanese math looks just like western math but is pronounced differently. However, I can't be sure >=X

... Am I seriously the only one on this forum that likes math?

It's interesting, though. I wonder if they use the same symbols for intergration and such... I will google it when I get back from running tonight and post it for you guys, because I'm sure you all love Calculus as much as I do :)

I'm back! Ok, it took me like 10 seconds to find this:

http://www.crossroad.jp/mathnavi/kousiki/bibun-to-sekibun/iroirona-kansuu-no-sekibun.html

Apparently, it's not just integration symbols that are the same. Things such as the trignometric functions (sine = sin, cosine = cos) and logs are the same too, pretty interesting...

You do mean that strictly in the context of mathematics, right? Because numbers are fairly frequently represented in kanji otherwise. Even phone numbers are sometimes written in kanji.

2 for 弐 can be the substitution. It's sometimes used on formal bills, checks, invoices, receipts etc.

Just FYI: Here're special kanji for traditional formal-billing work:
(normal - Arabic - billing)
零 0 零
一 1 壱(壹)
二 2 弐(貳)
三 3 参
四 4 肆
五 5 伍
六 6 陸
七 7 漆
八 8 捌
九 9 玖
10 拾
百 100 佰
千 1000 仟
万 10000 萬

Actually almost no one knows from-4-to-9 kanji (I've never seen) but you may see others sometimes. Please set the character size in the browser LARGER! :D

I guess the parenthesis would just be tied to the question number, such as:

Q1) 4 - 2 = ?


So, it's read as とい いち。よん ひく に は? (問1。四 引く 二 は)
