---|---|---|---|---|---|
\le | \ge | \neq | |||
\sim | \ll | \gg | |||
\doteq | \simeq | \subset | |||

Negations of many of these relations can be formed by just putting \not before the symbol, or by slipping an n between the \ and the word. Here are a few examples, plus a few other negations; it works for many of the others as well.

\boxed{Answer} produces a box around your Answer.
\frac{a}{b} produces a fraction with numerator and denominator .
^\circ produces the degrees symbol.
\text{Your Text Here} produces text within LaTeX. .
\mbox{Your Text Here} Produces text within LaTeX
\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.
{n}\choose{r} produces n choose r.
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.

\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
Also note that you do not have to use braces, "{" and "}", when you only want one character in the operation.
Examples
- x^y is the same as x^{y}.
- x_y is the same as x_{y}.
- BUT x^10 is not the same as x^{10}. instead of .
