Writing Mathematical Formulas in the GMAT Club Forums This post is just for those curious about writing neat maths formulae in forum posts... I looked it up because I was typing out questions and wanted to use symbols such as \leq rather than writing the 1 (2) highlight the text that is a formula, and then click the "m" button at the top of the edit box. This will enclose it with little "m" boxes (similar to adding color to a part of text), and tells the forum to display your text as a formula: x^2 + (x+3)^2 > 1 (3) that's it, simple. Most formula will display automatically. Fractions, roots and other exceptions are below. You can also see the detailed post by Bunuel here: rules-for-posting-please-read-this-before-posting-133935.html#p1096628 Common symbols that can be used within your formula (selected with GMAT in mind): Fractions: \frac{a+b}{c} --- \frac{a+b}{c} - note that numerator and denominator have to be enclosed in {} and you have to write out \frac to tell the system that it is a fraction. Powers and roots x^2 --- x^2 x^{12} --- x^{12} - note that multi-digit powers require {} \sqrt{x} --- \sqrt{x} - note the {} and \sqrt to identify the square root \sqrt {x} --- \sqrt {x} Inequalities \approx --- \approx \leq --- \leq \geq --- \geq \neq --- \neq Subscript x_1, x_2 --- x_1, x_2 Geometrical \pi --- \pi 90^{\circ} --- 90^{\circ} \alpha --- \alpha \angle --- \angle \triangle --- \triangle Full reference link for the extra curious: https://en.wikibooks.org/wiki/LaTeX/Mathematics#Math_operators

Hello Bunuel, below two signs in "Rules of posting" are displaying same formulas.

Could you please replace "\leg" with "\geq" for greater than or equal to sign?

how do i write the attached question using mathematical formula?

\(x=2(\frac{P}{Q})^{n-1}\)

\(\frac{P^{n-1}}{Q^{2n-1}}\)

Hope it helps.

Hi,

The symbol for least integer function is as follows:

\(\lceil x \rceil\): denotes the least integer greater than or equal to x.

Use following in math-mode:

Quote:

\lceil x \rceil

Thanks.

I am trying to write a response for a Critical Reasoning question, but the explanation could really benefit from a mathematical formula. It appears that mathematical formulas work great in the Quantitative forums, but whenever I type in "\(\mbox{[m]x^2+1}\mbox{[\m]}\)" it it doesn't create the equation in the preview; rather, it displays a weird formula that begins with a "\" and a "(". Is there any way to insert formulas into Verbal explanations?

Sure! Here is the link:
https://gmatclub.com/forum/in-a-certain ... 51545.html

I have tried putting in mathematical formulas into my replies, using 2 different computers and 3 different browsers. It is acting funny. But I have no problems putting in the exact same equations into replies for other Quantitative questions.

It worked for me: https://gmatclub.com/forum/in-a-certain ... l#p2236901 Not in preview though but it got posted correctly. Could you please try to post a formula there? Thank you.

Fantastic! Thank you, Bunuel! Whenever I post a solution, I always like to preview it, and it scared me a little bit when the preview wouldn't display correctly. (I am a perfectionist, and I didn't want a post of mine to look half-baked.)

After you checked that the formulas would still (eventually) post correctly, this gave me an idea that could work for anyone else who runs into this issue. I opened up a Quant question and wrote my reply in that editor. This allowed me to preview the formulas so I knew they looked good. Then, I just copied the text of that reply into a reply for the original Verbal question I wanted to answer. The math equations still looked terrible when I "previewed" the response, but when I hit "Submit," everything appeared the way it was supposed to be. Mission accomplished.

Topic name does not have formula support, so you should put just a plain text there. Edited. Check now: https://gmatclub.com/forum/if-x-0-is-x-y-369503.html

Hi Bunuel,
How do I give space between words in such expressions as it does not appear in the final text: (Even Integer)^{Any Positive Power}
Final Output: \((Even Integer)^{Any Positive Power}\)?

By including there " \ "

\((Even \ Integer)^{Any \ Positive \ Power}\).
