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 <= symbol (I was using quite a few of them, which was starting to look confusing)
Don't you think that {(\sqrt{9+sqrt{80}}+\sqrt{9-\sqrt{80}})^2} is much easier to understand than – (sqr root of (9 +sqr root of 80)+sqr root of (9 - sqr root 80))^2?

The simple instructions:
(1) write formula as usual, e.g. x^2 + (x+3)^2 > 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[n]{x} --- \sqrt[n]{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

Hello bb, I need your help. Is there a master list of all the symbols. I was trying to get the angle symbol and based on Latex website it should be \angle however this results into another type of angle symbol \angle on Gmatclub forums. Hopefully you can point to the right source.

Thanks!

Nookway - thank you for your commitment to the math symbols - your math posts rock!
Let me research with the tech experts. I believe the \angle one works with GMAT Tests - not sure why it would not work here....

Hi nookway,

I believe the symbols look different because we use slightly different software. We use the same '\angle' -> \angle symbol in our Math Tests.

There are two other types of angle symbols, but I'm not sure they are intended for geometry:
\langle - \langle
\rangle - \rangle


Hope this helps

Hi dzyubam,

Thanks for the clarification. It does seem there are some differences. \angle should work for me. The symbol I was referring to can be seen in the image below.

Thank you for asking!

Code:
You did everything right, just needed to put [m] tag in the beginning and [/m] in the end.
The M-tags (there is an "m" button) are used to identify beginning and end of the area that you want to be converted into a math symbol

I added them to your post - you can see the code if you hit EDIT

1. Slightly wrong topic to post this.
2. The time conversion formula you suggested does not always work. For example if you have 135 minute and 200 minutes, you will get 335, add 40 and you will get 375... what do you do with that?

I'd just use the "|" signs to enclose a particular expression. See an example below.

\sqrt{x^2} = |x|

Code:
[m]\sqrt{x^2} = |x|[/m]

Thanks for putting the pics. I'm a visual guy so that really helped. I was wondering what m-tags meant. I thought they were complicated html code.
