LaTeX Math
LaTeX offers the most comprehensive math markup of any software.
Contents
Usage
There are two ways to use math markup: inline math mode and display math mode.
An example of the inline style is \(a + bx = y\), whereas an example of display style is: \[ a + bx = y \]
Math Fonts
For curly letters, as in what is used for sigma algebras:
\mathcal{O}
For blackboard letters, as in what is used for matrices:
\mathbb{X}
Spacing
To insert horizontal spacing, try:
\quad for 1em
\qquad for 2em
\, for 3mu; note that 18mu = 1em
\: for 4mu
\; for 5mu
More generally, automated spacing in math mode is governed by these widths:
\thinmuskip, defaulting to 3mu
\medmuskip, defaulting to 4mu
\thickmuskip, defaulting to 5mu
Markup
Many symbols are available by name, or some contraction of the name.

Greek letters are available by name. Note that by default the lowercase letter is returned; capitalizing the name returns the uppercase letter. For example, \Phi gives Φ while \phi gives ϕ.
Many function notations are also available.

There are several sizes of parentheses, braces, and bars available. As a demonstration:
\Big( \big( (x + 1) + 1 \big) + 1 \Big) \Big[ \big[ \left[ x + 1 \right] + 1 \big] + 1 \Big] \Big| \big| |a| - |b| \big| - |c| \Big|
