Edit this post describes a situation where I was unable to view the HTML artifact allowing me to edit or delete a comment in Chrome.

First an apology, on breaking this question. I'm unable to edit my comment and the HTML link doesn't appear in the main site.

The comment I was trying to write was

w.r.t. "order of operations" in your final sample you have 
9\times 3\equiv 27 \equiv 7\pmod{10}$ 

why is it not written as  
9\pmod{10}$$ \times 3 \pmod{10}$$  \equiv 27\pmod{10}$$  \equiv 7\pmod{10}$$   
... in other words, when looking at one half of a congruence,
it's not immediately clear if \pmod{10}$$ has been applied or not.

I broke the internetz by deleting one of the "$" signs where the parsing seemed to make my plain text "mathified".

I'm new at se.Math and I'm new to this markup. Sorry about the bug I created/discovered!

  • $\begingroup$ Isn't this the same problem as here? If you can see cross which allows you do delete comment; then the solution is to delete it. If not you could perhaps try the workaround from that post, or flag for moderators attention and - hopefully - one of the moderators will delete the comment for you. $\endgroup$ – Martin Sleziak Oct 22 '13 at 15:58

    $\begingroup$ I've tried to fix it. Tell me if it looks correct. $\endgroup$ – user642796 Oct 22 '13 at 16:00
  • $\begingroup$ Also, in the future you can "test" your comments by typing them up as answers and checking the preview (and then copy-and-pasting it as a comment). If you run into this problem again flag either the comment (if possible) or the post to which it is a comment for moderator attention. $\endgroup$ – user642796 Oct 22 '13 at 16:06
  • $\begingroup$ @ArthurFischer Looks good, can you show me the code so I can learn from it? $\endgroup$ – goodguys_activate Oct 22 '13 at 16:07

  • $\begingroup$ @makerofthings7: here's the code w.r.t. "order of operations" in your final sample you have $9\times 3\equiv 27 \equiv 7\pmod{10}$ why is it not written as $9\pmod{10} \times 3 \pmod{10} \equiv 27\pmod{10} \equiv 7\pmod{10}$ ... in other words, when looking at one half of a congruence it's not immediately clear if $\pmod{10}$ has been applied or not. $\endgroup$ – user642796 Oct 22 '13 at 16:11
  • $\begingroup$ If you follow @ArthurFischer's suggestion to preview whatever you expect to be editing, as an answer, there is a "sandbox" thread for that purpose in meta. meta.math.stackexchange.com/questions/4666/… . If you do it under a question there are some side effects in the case of accidentally clicking Submit Answer, such as bumping the question and leaving a deleted answer visible to users with higher 'reputation' (awful word for it, sorry). $\endgroup$ – zyx Oct 22 '13 at 16:26

Regarding the comment not being editable: Comments can only be edited for 5 minutes after being posted. After that time a comment cannot be changed, though you can always delete it and post a corrected version.

  • $\begingroup$ also regarding this... I was unable to click on the edit or delete link because the HTML was rendered in a location I couldn't reach (due to rendering) $\endgroup$ – goodguys_activate Oct 24 '13 at 20:24

    $\begingroup$ @makerofthings7: Oh, I see. Maybe you should edit your question to clarify this. $\endgroup$ – Nate Eldredge Oct 24 '13 at 20:36
