B.22 Missing delimiter

You have forgotten to specify the type of delimiter you want (for example, ( ) [ ] \{ \}). (Remember to use a . if you want an invisible delimiter, and remember that if you want a curly brace, you must have a backslash followed by the curly brace.)

Example:

This error will occur if you do, say,


f(x) = \left{
\begin{array}{ll}
0 & x \leq 0\\
1 & x > 1
\end{array}
\right.
instead of

f(x) = \left\{
\begin{array}{ll}
0 & x \leq 0\\
1 & x > 1
\end{array}
\right.
