# Operadores no Calc de LibreOffice

You can use the following operators in LibreOffice Calc:

## Operadores aritméticos

These operators return numerical results.

Operador | Nome | Example
--- | --- | ---
Mais | Suma | 1+1
- (Menos) | Subtración | 2-1
- (Menos) | Negation | -5
Asterisk | Multiplicación | 2*2
/ (Barra) | División | 9/3
% (Porcentaxe) | Porcentaxe | 15%
Cursor | Exponentiation | 3^2

Prefix "-" (negation) has a higher precedence than "^" (exponentiation). For example -3^2 equals 9, which is the square of a negative number.

## Comparative operators

These operators return either true or false.

Operador | Nome | Example
--- | --- | ---
= (equal sign) | Igual | A1=B1
Maior que | Maior que | A1>B1
menor que | Menor que | A1<B1
Maior que ou igual a | Maior que ou igual a | A1>=B1
Menor que ou igual a | Menor que ou igual a | A1<=B1
<> (Inequality) | Inequality | A1<>B1

## Text operators

The operator combines separate texts into one text.

Operador | Nome | Example
--- | --- | ---
E | text concatenation AND | "Mér" e "cores" é "Mércores"

## Operadores de referencia

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

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

Operador | Nome | Example
--- | --- | ---
Colón | Intervalo | A1:C108, A:D or 3:13
! (Símbolo de admiración) | Intersección | 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.
~ (Til) | 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. =COUNT(A1:B2~B2:C3) counts values of A1:B2 and B2:C3. Note that the cell B2 is counted twice. =INDEX(A1:B2~C1:D2;2;1;2) selects cell C2, that is, the first cell of the second row, first column, of the second range (C1:D2) of the range list.

A reference list is not allowed inside an array expression.
