Equations over more than one line
Suppose you want to type an equation covering more than one line. For
example:
x=3
y=1
Your first reaction would be to simply press the Enter key. However, if
you press the Enter key, though the markup goes to a new line, the
resulting equation does not. You must type the newline command
explicitly. This is illustrated in the table below.
Markup Result
x = 3
y = 1
x=3 y=1
x = 3 newline
y = 1
How do I add limits to my sum/integral?
The sum and int commands can (optionally) take the parameters from
and to. These are used for lower and upper limits respectively. These
parameters can be used singly or together. Limits for integrals are
usually treated as subscripts and superscripts.
