Writing Mathematical Formulas on the Forum



I think that everybody will agree 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.

So, in order to help you with the questions you post more efficiently please use the following guide to write math formulas.

In most cases you'll just need to do 2-3 simple steps:

Simple Formulas


How to make 7x^2+5(x+3)>1 to look like \(7x^2+5(x+3)>1\)
Step 1: Mark 7x^2+5(x+3)>1;
Step 2: Press m button.


Fractions


How to make (x+3)/(x+5)>0 to look like \(\frac{x+3}{x+5}>0\):
Step 1: Mark the fraction (x+3)/(x+5);
Step 2: Press fraction button;
Step 3: Now, mark the whole expression and press m button.


Square roots


How to make (x+5)^(1/2)<17^(1/2) to look like \(\sqrt{x+5}<\sqrt{17}\):
Step 1: Mark x+5 and press square_root button, then mark 17 and press square_root button again;
Step 2: Now, mark the whole expression and press m button.


Other Useful Symbols



Another Way of Writing Fractions:
How to make (a+b)/c to look like \(\frac{a+b}{c}\)
Step 1: Write \frac{a+b}{c}, (note that numerator and denominator must be enclosed in { } and you must write out \frac to tell the system that it is a fraction);
Step 2. Mark the whole expression and press m button.

Exponents
How to make x^12 to look like \(x^{12}\)
Step 1: Write x^{12}, (note that multi-digit powers must be enclosed in { });
Step 2. Mark the whole expression and press m button.

Roots
How to make 3rd root of x^2 to look like \(\sqrt[3]{x^2}\)
Step 1: Write \sqrt[3]{x^2}, (note that 3 must be enclosed in [ ] and 2 must be enclosed in { });
Step 2. Highlight the whole expression and press m button.

Inequalities
\(x\approx{3}\): write x\approx{3} and press m button (note that 3 must be enclosed in { }).
\(x\leq5\): write x\leq{5} and press m button.
\(x\geq3\): write x\geq{3} and press m button.
\(x\neq0\): write x\neq{0} and press m button.

Subscript
\(x_1\): write x_1 and press m button. If a subscript is more than one-digit number, for example \(x_{15}\) then write x_{15} and press m button (note that such kind of subscripts must be enclosed in { }).

Geometry
\(\pi\): write \pi and press m button;
\(\angle\): write \angle and press m button;
\(90^{\circ}\): write 90^{\circ} and press m button;
\(\alpha\): write \alpha and press m button;
\(\triangle\): write \triangle and press m button.

When you make new post below the frame when you insert the question you have the tags, specifically, the difficult level, the topic such as algebra, and the source of the question.

Usage of the Tags



You might have noticed that most forum threads have tags.

Attachment:
#GREPrepclub Tags.jpg


These tags act as markers for the topic matter of the forum' discussions.



Adding the Tags

If you are creating a new thread, it can be helpful to add the tags.
There is a Topic Tags box just beneath the space where you write your forum post, and here you can add your tags.

Navigating via Forum Tags

If you want to find other threads that have been tagged, merely the search button at the upper leftmost.

Attachment:
#GREPrepclub Search.jpg


and then go to the bottom of the page you do appear, in the last frame you do have the search by tags.

#GREPrepclub Tags 3.jpg


Click on one sub-forum you might be interested in, and this will appear (in this case I have used Quantitative Comparison forum, to search for all the QC questions I have interest in to find out )

Attachment:
#GREPrepclub Tags 4.jpg


perform your searching, checking the box/boxes you do have in mind.


What if I want the questions under quantitative comparison questions, tagged as hard and word problems, from only PowerPrep II as a source? Use the following option as shown in the following screenshot

#GREPrepclub Tags 5.jpg



Select this button to search for specific tags you want. Any tag means - if one of the five chosen, that result will show up.


This is super helpful. Thank you so much :)
