    How do I use the math tags?

    Hey,

    I know that if you punch the "E" above when you post it will wrap math tags around what you're inserting. How do I write the square root correctly and how do i do the division symbol if I were to do fractions?

    Thanks!

    Experimenting:

    x^2

    6/7

    x^1/2

    /frac{/3}{5}

    Thanks, didn't realize that would be the name. I was thinking of this documentation software named LateX.

    I still don't get how to do the fractions. They suggest you do (/frac) but for the "/" symbol they have it reflected. How do I find that on the keyboard? Can someone give me the steps to do a fraction such as 1/2? Thanks!

    Yes, it is a backslash in front of the frac command.

    \frac{Numerator}{Denominator} gives \frac{\textrm{Numerator}}{<br />
\textrm{Denominator}}

    E.g. \frac{1}{2} gives \frac{1}{2}.

    The backslash is usually located above the enter key.


    The radical symbol is given by

    sqrt{Something}

    which gives

    \sqrt{\textrm{Something}}.

    E.g. \sqrt{2} gives \sqrt{2}.


    If you want a higher root, like a cube root, then you'd put

    sqrt[n]{Something}

    to gives

    \sqrt[n]{\textrm{Something}}.

    E.g. \sqrt[3]{4} gives \sqrt[3]{4}.
