12 Rules for Posting - Please Read this Before Posting New Question




Following the simple rules and suggestions below can help you, other members, and our moderators to be happier people. Yes, truly, we will all be happier! When you create mis-catagorized, or poorly-posted quant questions, it leads to confusion and diminishes the valuable forum content. It also makes our lives stressful and disorganized. However, if you follow these 11 simple suggestions, you can expect great karma, good looks, and extra points on the GRE! If by chance that did not convince you, ignoring or breaking these rules will likely lead to removed posts, warnings, eventual bans, and a possible hair loss. Please follow the rules. Thank you!

    1. Use the Search Box Before Posting.

    - Before to post a new one question, is important to use this powerful tool. Otherwise, we are going to create duplicated post. Use it wisely
    - Forum Search

    2. Choose the Right Forum.

    - Please post Numeric Entry Question, Quantitative Comparison Question, Multiple-choice Questions — Select One or More Answer Choices, Multiple-choice Questions — Select One Answer Choice, Data Interpretation Sets in their respective sub-forum. No posting questions is allowed in the main GRE Quantitative Section.

    3. Give a Topic Name (IMPORTANT).

    - Use the first sentence of the question or a string of words exactly as they show up in the question. You get 40 characters. Use them all to help with the search & similar topics feature!

    4. Post Only one Question per Topic.

    - Please do not post multiple questions in the same post as it makes timer, search, tags, and other functions irrelevant.

    5. Do not Change the Question.

    - It is extremely important that the integrity of the original question is maintained. Remember, every word that is included in a question is there for a reason!

    6. TYPE the Question in as Text.

    - Do not post pictures of questions. The only time a picture is acceptable is when a question has a diagram. If a diagram exists, make sure to always attach it using JPG/GIF/PNG formats. Do not use Word or PDF documents.

    7. Indicate the OA (Official Answer)

    - Use the A, B, C, D, E radio buttons and make sure you post the answer choices.

    8. Post Always The Answer Choices for Math Questions

    - One should always look at the answer choices before starts to solve a problem. They might often give a clue on how to approach the question.

    9. Use Formulas that Look Like Formulas!

    - Help us to help you. It is quite easy, and will increase the value of your questions. Also check How to Write Mathematical Formulas on the Forum

    10. Tag Your Questions.

    - At least 3 tags are required: difficulty level (in your opinion), question category, and source of the question. You are welcome to use more tags as applicable. You can also TAG other people’s posts to make them more valuable.

    11. Avoid Short/Useless Posts (they will be deleted) and use the Kudos Button Instead.

    - If you choose to answer a question, please answer only if your post adds value. Saying “+1 A”, "Awesome solution!" or “Great Question!” does not. Pressing the Kudos button does.

    12. ONLY Questions from Reliable GRE Sources are Allowed on the Forum!

    - Please do NOT post questions from random math books and web sites.

Thank you! We appreciate your understanding and support. Good luck on the GRE!

Writing Mathematical Formulas on the Forum



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: Highlight 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: Highlight the fraction (x+3)/(x+5);
Step 2: Press fraction button;
Step 3: Now, highlight 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: Highlight x+5 and press square_root button, then highlight 17 and press square_root button again;
Step 2: Now, highlight 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. Highlight 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. Highlight 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.
