I am writing a math paper and my teacher said there are some English errors in the sentence that I use below; but, I don't know how to fix it.

See Conway's book for more information that set A is closed.

Thank you in advance!!

  • Let me make one thing clear here. Are you asking for proofreading? – Michael Rybkin Apr 10 '18 at 19:21

  • Welcome to EL&U. Please note that requests for proofreading are explicitly off-topic, but furthermore, there are no obvious errors in your sentence. It might not make sense in context, but you have not provided us with any context. I strongly recommend you take the site tour and review the help center for a better understanding of how to present a question that is answerable in our format. Our sister site for English Language Learners may also be of interest, though you should note that all of Stack Exchange expects you to demonstrate your own research first. – choster Apr 10 '18 at 19:22

    @Stan I don't know this sentence is pretty clear to me. Do you find any English mistakes? – Answer Lee Apr 10 '18 at 19:26

    I don't; but, I'm a math teacher. – Stan Apr 10 '18 at 19:28

I can find no indication that there is a problem with your English construction. Perhaps it's the meaning of your statement — the significance of it.

Perhaps your instructor has a problem with how you refer to Conway's book - the reference.

Is Conway's book specifically about set A and closed sets; or, is the reason set A is closed dealt with somewhere within the comprehensive content of Conway's work on Set Theory?

Might one see Conway's book for more information about why set A is closed? If this is true, the instructor would be making a comment about the significance of your advice.

It could be that your instructor gave you a misguided answer sending you in the wrong direction for the correct response. It might have been for your choice of words.

  • Thanks for your answer. I think he wants me to use about why instead! – Answer Lee Apr 10 '18 at 20:02

Your instructor might be looking for something like:

See Conway's book for more information as to why set A is closed.


See Conway's book for more information that proves set A is closed.


More information of set A's closure can be seen in Conway's book.

The 'correct' structure of the sentence really depends on what your instructor is looking for. Honestly, they probably don't know themselves. I hope this is at least somewhat helpful.

  • Actually, the school probably does have a standard for citing texts and it probably looks more like "The course text shows why Set A must be closed (Conway, 78)" than any of the examples we've been providing. It's academic writing. ;-) – Lowell Montgomery Apr 10 '18 at 20:34
  • I didn't initially view this a citation, but rather a recommendation. Anyway, the citation wouldn't be "(Conway, 78)". You have already stated the authors name in the sentence, so you would only need the page number in the citation. That's assuming there is only one book by that author referenced in the bibliography. Although, it really depends on which standard you are using for your citations. This whole thread is a toss-up because there isn't sufficient information. – Quinn Apr 10 '18 at 20:40
  • Right. (Well, my example, above, used only the author's name in the parentheses, but if there were only one course text, you could even leave that out, too. But page numbers are normally expected when making an assertion and citing where we can find proof. I think we can agree on that. – Lowell Montgomery Apr 10 '18 at 20:56

The intended meaning of your sentence could be correctly re-phrased multiple ways:

"See Conway's book for more information that set A is closed." (original/incorrect)

"See Conway's book for proof that set A is closed."

"For an explanation of why set A is closed, see pages 78–80 of Conway's book."

"Conway explains why Set A is closed on pp. 78-80 of the course text."

"The reason set A is closed is explained on pages 78–80 of the course text by Conway."

Note: My choice of "pp 78–80" is arbitrary. I don't have your text. But it is pretty standard to show page numbers when citing references in academic papers. If "Conway's book" is the course text, and you aren't using multiple texts by the same author, and the reader is expected to know which text is meant, course texts are frequently just cited as the author's name and page numbers, with or without a comma between, depending on the standard. Find out what the standard is at your school and use the standard when citing texts.

So that might best look like: "Conway proves that Set A must be closed (Conway, 78–80)."
