The reason why I'm writing this note, is that there are some things which people (especially the people that write problems and solutions) should know. This can really reduce the need of edits by Moderators.

Together, we can make it clearer and hence, more enjoyable.

\(\color{Red}{\mathbf{1.}}\) Please try to use \(\LaTeX\) mathematical formatting. You can find the guidelines while posting the problem, as shown in the picture that follows, and also here

\(\color{Red}{\mathbf{2.}}\) Do \(\textbf{NOT}\) wrap all of your question in the \ ( ....... \ ) . Wrap ONLY the Math terms in the \ ( ...... \ )

I've seen people who post something like

### Find \quad the \quad value \quad of \quad the \quad integral \quad \int_0^1 x^7 dx

which appears as

\(Find \quad the \quad value \quad of \quad the \quad integral \quad \int_0^1 x^7 dx\)

\(\bullet\) They use the '\quad' for separation between the words,because the \ ( ........ \ ) wrapping doesn't take into account the spaces .

\(\bullet\) The more preferable way for this is, write only the math term in \ ( ..... \ ) and it will appear as

Find the value of the integral \(\int_0^1 x^7 dx\)

\(bullet\) This way, the paragraph and alignment formatting will be automatically considered, for example

\(My\quad name\quad is\quad Aditya\quad and\quad I\quad love\quad solving\quad problems\quad on\quad Brilliant.org\quad very\quad much.\quad See\quad the \quad math\quad \dfrac{\sqrt{1234}}{\sqrt{4321}}\)

In the above display, you are having to scroll to read it all (If not here, in problems you surely have to scroll).

\(\bullet\) But if the wrapping is only around the math terms, then It will appear as

My name is Aditya and I love solving problems on Brilliant.org very much. See the math \(\dfrac{\sqrt{1234}}{\sqrt{4321}}\)

\(\color{Red}{\mathbf{3.}}\) Please use the symbol \(\dbinom{n}{r}\) instead of \(^nC_r \).

\(\bullet\) The \(\LaTeX\) code is \binom{n}{r}, and for clearer display , use \dbinom{n}{r}

\(\bullet\) Use this, because when the binomial coefficient is preceded by some number, one could misread \(6^nC_r\) , which is actually \(6\times ^nC_r\), as \(6^n\times C_r\) .

\(\color{Red}{\mathbf{4.}}\) Whenever it's difficult or lengthy to explain the question by words (mostly in Geometry Problems) , give a diagram with the question. You may use softwares like Geogebra or Asymptote

\(\color{Red}{\mathbf{5.}}\) Whenever an image is taken from some source (like some website or somewhere), at times it may be subject to copyright, so just give the source of the image at bottom of the question (preferably a link to the source).

\(\bullet\) Write image credit - < source > preceded by 6 '#' signs. For example, writing \(\text{###### Image Credit wikipedia}\) will appear as

###### Image Credit Wikipedia

\(\bullet\) This way, write the Credit at the bottom of your question. An example can be seen in this problem

Further, the more issues i notice will be added here, and additions are welcome!
