Consider the following mathematics question,

Each of integers from 1 to N is written on a separate piece of card.

It means that there are N cards, each with a distinct number.

Is it understandable if I say as follows in Japanese?

    @brokenheadphones: If you assume no duplicates, then I don't find the original sentence ambiguous. But without that assumption, I think it could be seen as ambiguous, because then you could have N integers and >N cards. For example, if there were 5 cards with '1' on it and all other integers from 2..N each appeared on only one separate card, then there would be a total of N+4 cards. – istrasci Feb 17 '17 at 17:06

In math questions, you would usually say like this:

or 「N枚のカードに、それぞれ1からNまでの異なる整数が1つずつ書かれています。」

It's also common to say like this:

or 「1からNまでの異なる整数が1つずつ書かれたN枚のカードがあります。」

I think you could also say like this:

or 「N枚のカードがあり、それぞれに1からNまでの異なる整数が1つずつ書かれています。」

or maybe like this, but this might be a bit wordy:



Each of(各々{おのおの}の) integers(整数(は or が)) from 1 to N(1からNまでの) is written(書かれています) on a separate piece of card(それぞれ一枚のカードに).

Then the following is the best translation.


Your translation


"整数のめいめい" is just acceptable as a translation by non-native Japanese speaker, at least you should use "めいめいの整数." "それぞれの整数" is far better.

If the N numbers (from 1 to N) are written in a card, it should be traslated into "1からNまでの整数が、一枚のカードに書かれています。"
There is no need to use "各々," "それぞれ" or "めいめい" to describe this picture. There are two substances, one is a group of Numbers and the other is a card.


I think "めいめい" is usually used for people to mean each person.

So, your sentence "一からNまでの整数のめいめいはそれぞれ別のカードの一枚に書かれた。" can be rephrased to read as follows:



「カード一枚ずつに一つの整数」 means "one integer for each card" or "one integer per card". The key you are looking for is "ずつに".

「1からNまで、カード一枚ずつに一つの整数 ...」
