You can choose various unary and binary operators to build your LibreOffice Math formula. Unary refers to operators that affect one placeholder. Binary refers to operators that connect two placeholders. The lower area of the Elements pane displays the individual operators. The context menu of the Commands window also contains a list of these operators, as well as additional operators. If you need an operator that is not contained in the Elements pane, use the context menu or type it directly in the Commands window.
