How to Write Greater Than or Equal to in Latex
Math can be written in the wiki in the form of LaTeX, a typesetting language used primarily to type mathematical expressions in an elegant fashion. For example, without LaTeX, would have to be written as 35/137. To use LaTeX in the forums, enclose your LaTeX code with dollar signs: <dollar/>your codes here<dollar/>. You can also use double dollar signs or other normal indicators: <dollar/><dollar/>your codes here<dollar/><dollar/> or \[your codes here\]. (There are also deprecated [tex] tags, but let's not get into that) To use LaTeX on AoPSWiki, you can enclose the code with dollar signs as in the forum, or you can also enclose your code with math tags, like so: $your codes here$.

\sqrt{x} produces the square root of .
\sqrt[n]{x} produces the th root of .
a\equiv b \pmod{c} produces is equivalent to mod . See Modular Arithmetic
\binom{9}{3} produces 9 choose 3.
x^{y} produces x to the power of y.
x_{y} produces x with y in subscript.
\rightarrow produces an arrow to the right.
\leftarrow produces an arrow to the left.
\uparrow produces an arrow pointing upwards.
\downarrow produces an arrow pointing downwards.
\updownarrow produces an arrow pointing up and down.
\ge produces a greater than or equal to sign.
\le produces a less than or equal to sign.
\not> produces a not greater than sign.
\not< produces a not less than sign.

\angle produces an angle sign.
\triangle produces a triangle.
\ldots produces three dots at the bottom of a line (ellipsis).
\cdots produces three dots in the middle of a line (as in a series sum or product).
\times produces an as used in multiplication
\otimes produces a
is in math mode by default, so there's no difference between \frac{}{} and \dfrac{}{}, for example. Also note that you do not have to use braces, "{" and "}", when you only want one character in the operation.
