LibreOffice 7.6 Help

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.

The following is a complete list of the unary and binary operators. The symbol next to the operator indicates that it can be accessed through the Elements pane (choose View - Elements) or through the context menu of the Commands window.

Plus/Minus

Inserts a plus/minus with one placeholder. You can also type +-<?> in the Commands window.

Minus/Plus

Inserts a minus/plus with one placeholder. You can also type -+<?> in the Commands window.

Addition (plus)

Inserts a plus with two placeholders. You can also type <?>+<?> in the Commands window.

Množenje (vektorsko)

Inserts a dot operator with two placeholders. You can also type <?>cdot<?> in the Commands window.

Množenje (vektorsko)

You can also insert user-defined unary operators by typing uoper in the Commands window, followed by the syntax for the character. This function is useful for incorporating special characters into a formula. For example, the command uoper %theta x produces a small Greek letter theta (a component of the LibreOffice Math character set). You can also insert characters not in the LibreOffice character set by choosing Tools - Symbols - Edit.

You can also insert user-defined binary commands by typing boper into the Commands window. For example, the command y boper %theta x produces the small Greek letter theta preceded by a y and followed by an x. You can also insert characters not in the LibreOffice character set by choosing Tools - Symbols - Edit.

By typing <?>oplus<?> in the Commands window, you insert a circled plus operator in your document.

Type <?>ominus<?> in the Commands window to insert a circled minus operator.

Type <?>odot<?> in the Commands window to insert a circled dot operator in the formula.

Type <?>odivide<?> in the Commands window to insert a circled division operator in the formula.

Type a wideslash b in the Commands window to produce two characters with a slash (from lower left to upper right) between them. The characters are set such that everything to the left of the slash is up, and everything to the right is down. This command is also available in the context menu of the Commands window.

Type a widebslash b in the Commands window to produce two characters with a slash (from upper left to lower right) between them. The characters are set such that everything to the left of the slash is down, and everything to the right is up. This command is also available in the context menu of the Commands window.

Type sub or sup in the Commands window to add indexes and powers to the characters in your formula; for example, a sub 2.

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.

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.
