Operation Manual

Note
In localized versions of LibreOffice, the names of special characters are also localized.
If a document is not localized to the same language, then the names of special
characters in the following table may not work correctly. If this happens, you can use
the Symbols dialog to select the required special character. When selected in the
Symbols dialog, the name of the special character is displayed at the bottom of the
Symbols dialog in the correct language. See Chapter 1 Creating & Editing Formulas for
more information on special characters and the Symbols dialog.

Reserved words
A reserved word is a word that is used by LibreOffice as a command in the Math markup language
and it cannot be used as a variable name or entered into a formula as text. However, if you want to
use a reserved word as text in a formula then you must place the reserved word between double
quotes.
For example, you want to use the word “purple” in a formula, but do not want the formula elements
to be changed to the color purple. If you simply type A purple B in the Formula Editor, the
resulting formula is
A ¿ B
, which is incorrect and the error is shown by the upside question mark.
To correct this error, type A "purple" B in the Formula Editor using double quotes each side of
the word purple and the resulting correct formula is
A purple B
.
The reserved words used in Math are listed in the above tables for commands in markup language.
