# Why does Brilliant disable a user from leaving a new answer after deleting an answer?

I am new here; i just joined today. But I haven't been posting answers, I just solve them and go right ahead because the LaTeX formatting never comes out right in the preview.

Just now, I finally decided to post a Math answer anyway, but it was unreadable. I deleted my answer, thinking I'll answer the question again - but this time I'd format it offline, take a screenshot and upload the image. Alas, I was not allowed to post a new answer.

This problem

I must say it is a rather frustrating experience.

Hi Oyekola,

Welcome to Brilliant!

1) We limit the number of solutions that you can submit to only 1, which is why you couldn't submit your another solution.

2) To get the latex code to display, you have to use the brackets $$\backslash ( \quad \backslash)$$ around your Latex code. I've updated your solution so that you can refer to it, by clicking on the edit button.

3) To use markdown to display hyperlinks (in this note) or images (in the problem), you should not leave a space between [] and (). I fixed it in both instances, so you can edit it to take a look.

I have undeleted your solution, and edited the Latex (by simply adding the relevant brackets around your Latex code.) If you do not want to display your solution, you may delete it.

P.S. You have great Latex skills! Staff · 2 years, 1 month ago

Hello Calvin, thanks for your response. I looked round for an appropriate discussion board or else a contact email but when I found none, I posted a note instead.

(1) Alright, I understand this. (2) I am not sure this is included in the formatting documentation, or else I missed it. I'll take note of this going forward. I can see that you've posted the answer for me. Thanks. (3) Okay, I see. I understand this better now.

Thanks again! · 2 years, 1 month ago

For more information, you can refer to the Math Formatting Guide. There should be an immediate link when you are writing a solution.

In general, any site that display math equations using MATJAX / LATEX, will require you to denote the relevant portions that should be encoded. We use $$\backslash( \quad \backslash)$$, while other sites may use  or .

Apart from this instance, how do you find your Brilliant experience? Staff · 2 years, 1 month ago

I'm absolutely geeking out here and enjoying the experience. Brilliant is splendid! I wish I knew about the site earlier on. I randomly stumbled upon it today while doing a bit of number theory research.

Now that I've cleared up this formatting problem, it should be even more interesting. And I think I'll be willing to give $$Brilliant^2$$ a shot shortly. I got the Android app also so I can have more Brilliant days. · 2 years, 1 month ago

That's great to hear! I'm glad that you are geeking out on our site and loving it :) Let me warn you that it can get addictive!

What number theory research are you working on? Staff · 2 years, 1 month ago

Hahaha I can already tell that it is addictive. I've hardly done very much else over the past day.

I recalled a tough number theory question from a paper I took last October: i.e. the GRE Subject Test in Math. I was trying to see if there was an analytical way to solve it, because during the exam I used some time wasting brute force. I'm still looking.

Sadly by ETS rules, I am not permitted to go into detail about any of the questions on the exam, or create a similar question for the sake of review by a third party. · 2 years, 1 month ago
