# Operators in LibreOffice Calc

You can use the following operators in LibreOffice Calc:

## Arithmetical Operators

These operators return numerical results.

Operator | Navn | ### Example
+ (Plus) | Addisjon | 1+1
- (Minus) | Subtraksjon | 2-1
- (Minus) | Negasjon | -5
* (stjerne) | Multiplikasjon | 2*2
/ (skråstrek) | Divisjon | 9/3
% (Prosent) | Prosent | 15 %
^ (sirkumfleks) | Exponentiation | 3^2

## Comparative operators

These operators return either true or false.

Operator | Navn | ### Example
= (likhetstegn) | Lik | A1=B1
> (Større enn) | Større enn | A1>B1
< (Mindre enn) | Mindre enn | A1<B1
>= (Større enn eller lik) | større enn eller lik | A1>=B1
<= (Mindre enn eller lik) | mindre enn eller lik | A1<=B1
<> (Ulikhet) | Ulikhet | A1<>B1

## Text operators

The operator combines separate texts into one text.

Operator | Navn | ### Example
& (Og) | text concatenation AND | "Sun" & "day" is "Sunday"

## Reference operators

These operators return a cell range of zero, one or more cells.

Range has the highest precedence, then intersection, and then finally union.

Operator | Navn | ### Example
: (kolon) | Område | A1:C108
! (Utropstegn) | Snitt | SUM(A1:B6!B5:C12) Calculates the sum of all cells in the intersection; in this example, the result yields the sum of cells B5 and B6.
~ (Tilde) | Concatenation or union | Takes two references and returns a reference list, which is a concatenation of the left reference followed by the right reference. Double entries are referenced twice. See note below this table.

Reference concatenation using a tilde character was implemented lately. When a formula with the tilde operator exists in a document that is opened in old versions of the software, an error is returned. A reference list is not allowed inside an array expression.
