What is WOOT? WOOT stands for Worldwide Online Olympiad Training and is a 7-month high school math Olympiad preparation and testing program that brings together many of the best students from around the world to learn Olympiad problem solving skills. Classes begin in September!

Do you have plans this summer? There are so many options to fit your schedule and goals whether attending a summer camp or taking online classes, it can be a great break from the routine of the school year. Check out our summer courses at AoPS Online, or if you want a math or language arts class that doesn’t have homework, but is an enriching summer experience, our AoPS Virtual Campus summer camps may be just the ticket!

Error in Special AIME Seminar A solution
fermat_sLastAMC   1
N Today at 4:22 AM by MathPerson12321
The text in the following image (of the solution for problem #3 of the practice AIME of 4134 Special AIME Seminar A) should state that the positions of A and B are plotted on the vertical and time is plotted on the horizontal.

Where should I post these kinds of errors in the future?

Contest collection PDFs don't work when LaTeX is embedded within BBCode
Equinox8   5
N Yesterday at 11:26 PM by jlacosta
This could very well be reported before, however a quick search did not find anything.

While embedding LaTeX commands within BBCode (like this: [i]text $\dfrac{1}{2}$ text[/i]) typically displays as intended within a forum, trying to render a contest collection using these commands breaks the PDF renderer.

As outlined in this (locked) post, the forum/blog creation message is out of date. It has been over a year since that post, and it still has not changed. I don't know if this got lost somewhere in the "passing this along" chain or if it was determined to be irrelevant, but it seems like a relatively simple fix ;)

Strange LaTeX inconsistency
w32dedorh30   10
N Feb 18, 2025 by miles888
LaTeX renders things differently and for this example, it all depends on a space.

When you type
[code]$k = - 3.$[/code],
LaTeX renders $k = - 3.$,
but when you type
[code]$k = -3.$[/code],
LaTeX renders $k = -3.$

For some reason, in the bottom example, it becomes stretched vertically. Why? Is there anything that AoPS can do to fix this?

This is a well-known issue that involves latex catching. For example, here’s a common one:

This code
$\triangle ABC$

renders $\triangle ABC$.

This code
$\triangle ABC~$

renders $\triangle ABC~$.

Side-by-side for emphasis: $\triangle ABC$ vs $\triangle ABC~$

For your post, i can see the different but in the OP I can't see any difference? Is there any reasoning for that??

Sorry, I missed that. For those who see the two in the OP as different, what browser and operating system are you using? The two appear the same to me on macOS 13.4 on both Safari and Chrome.
