Matematinių operacijų ženklai

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.

Tip Icon

If you want to use a colon ':' as division sign, choose Tools - Symbols or click the Symbols icon on the Tools bar. Click the Edit button in the dialog that appears, then select the Special symbol set. Enter a meaningful name next to Symbol, for example, "divide" and then click the colon in the set of symbols. Click Add and then OK. Click OK to close the Symbols dialog,too. Now you can use the new symbol, in this case the colon, by entering its name in the Commands window, for example, a %divide b = c.


Warning Icon

When entering information manually in the Commands window, please note that a number of operators require spaces between the elements for the correct structure. This is especially true if you are using values instead of placeholders in your operators, for example, to construct a division 4 div 3 or a div b.
