Using &quot; left &quot; and &quot; right &quot; makes the above expression valid in $[officename] Math: &quot; left [2, 3 right ) &quot; . However, the brackets do not have any fixed size because they adjust to the argument. Setting a single bracket is a bit cumbersome. Therefore, there you can display single brackets with a fixed size by placing a &quot; \ &quot; (backslash) in front of normal brackets. These brackets then act like any other symbol and no longer have the special functionality of brackets; that is they do not work as group builders and their orientation corresponds to that of other symbols.
