$ … $ delimiters for inline math, or $$ … $$ delimiters for display math. The examples here use display math.Contents
A
aligned
Align equations… each line of the equation will align on &, and new lines are created with \\.
\begin{aligned}
a - (b + c) &= a + (-1)(b + c)\\
&= a + (-1)b + (-1)c\\
&= a - b - c
\end{aligned}\begin{aligned} a - (b + c) &= a + (-1)(b + c)\\ &= a + (-1)b + (-1)c\\ &= a - b - c \end{aligned}
B
blackboard bold (mathbb)
Commonly used in set notation.
\mathbb{R}, \mathbb{Z}\mathbb{R}, \mathbb{Z}
C
centered dot (\cdot)
x \cdot yx \cdot y
centered dots (\cdots)
a_1 + \cdots + a_na_1 + \cdots + a_n
D
degree
Use Unicode for these outside of mathematics contexts.

delimiters \left( \right) \left[ \right] \left\lbrace \right\rbrace \left| \right|
This type of delimiter (i.e. parenthesis, brackets, braces, bars) scales to the size of the contents.
\left(\frac{x}{y}\right)\left(\frac{x}{y}\right)
\left[ \frac{x}{y} \right]\left[ \frac{x}{y} \right]
\left\lbrace \frac{x}{y} \right\rbrace\left\lbrace \frac{x}{y} \right\rbrace
\left| \frac{x}{y} \right|\left| \frac{x}{y} \right|
dots/ellipsis (\dots)
\{a_1, a_2, \dots\}\{a_1, a_2, \dots\}
