    Nope, I just saw it somewhere and really looks cool

    The old command was either \ooint or \oiint
    But they do not work now.


    What command did you use to create your avatar on AoPs?
    You can use \mathop{{\int\!\!\!\!\!\int}\mkern-21mu\bigcirc}{}

    This yields \mathop{{\int\!\!\!\!\!\int}\mkern-21mu\bigcirc}{}

    How can I insert an image in my post?
    I used the "Insert image " button, but one ask me to introduce the URL and the image is in my own computer.

    You can use ImageShack

    It's the best way to upload & plug the images to the forum

    I've never used Image Shack on this site. I always upload from my computer. Go to "manage attachments", then click on browse at "upload file from your computer". It's always worked great for me.

    Really?. That's odd. It's there when I click "post reply". Scroll down to it. That doesn't make sense.

    It's right beneath where you write your post. Under "Additional Options", "Attach Files". There's a icon bar that reads "Manage Attachmants".

    Is it possible to create the command
    Code:
    \gal
    To produce \mbox{Gal}.
    Instead of writing,
    Code:
    \mbox{Gal}
    And hence saving time?

    I have more such commands which I end up using. So if it possible I can create a list.

    I think it's possible to set a command like that.

    You can also write in text using \text

    Not hard.

    P.S.: or for some special commands, using \mathrm

    The standard LaTeX method of creating commands does not work.

    Code:
    \newcommand{\gal}{\ensuremath{\mbox{Gal}}}
    \gal
    \newcommand{\gal}{\ensuremath{\mbox{Gal}}}<br />
\gal

    Can someone please give me the code for:

    1. 3^(3x +4).18^(-x-2)/24^(x+3).4^(-2x-1)



    2. 21^(3x+1).7(2-x)/49^(x-1).27^(x-4)

    Thanks in advance.

    Thanks in advance.
    3^(3x +4).18^(-x-2)/24^(x+3).4^(-2x-1)

    \frac{3^{3x +4}.18^{-x-2}}{24^{x+3}.4^{-2x-1}}

    which is generated by:


    [tex]\frac{3^{3x +4}.18^{-x-2}}{24^{x+3}.4^{-2x-1}}[/tex]


    21^(3x+1).7(2-x)/49^(x-1).27^(x-4)

    \frac{21^{3x+1}.7^{2-x}}{49^{x-1}.27^{x-4}}

    which is generated by:


    [tex]\frac{21^{3x+1}.7^{2-x}}{49^{x-1}.27^{x-4}}[/tex]
