You can add operator manually by typing them in the formula area or select them from the list of operators available in the formula editor. There are several groups of operators in the formulas which are covered in the following sections. ## Arithmetic operators Arithmetic operators perform common arithmetic operations with numeric values. The parameters of the arithmetic expressions are handled as the decimal values. The parameters of any other data type will be converted to the decimal type.
Operator Description and examples
+ (addition)

Adds the value of one numeric expression to another or concatenates two strings.

Example: =A10+B10

Here, A10 and B10 are cell references. If the values in the cells are 12.85 and 2.25, the result of the expression would be 12.85 + 2.25 = 15.1.
+ (subtraction)

Subtracts the value of one numeric expression from another.

Example: =A20-B30

Here, A20 and B30 are cell references. If the values in the cells are 12.85 and 2.25, the result of the expression would be 12.85 - 2.25 = 10.6.
* (multiplication)

Multiplies the value of two expressions.

Example: =C10*D10

Here, A20 and B30 are cell references. Assuming that the parameters have the values C10 = 2.25 and D10 = 2, the example would evaluate to 2.25 * 2 = 4.5.
/ (division)

Divides the values of two expressions.

Example: =A10/C10.

Here, A10 and C10 are cell references. If the values in the cells are 4.0 and 2.0, the result of the expression would be 4.0 / 2.0 = 2.0.
% (Mod)

Divides two numbers and returns only the remainder.

Example: =B15 % C15

Here, B15 and C15 are cell references. If the values in the cells are 15.0 and 6.0, the result of the expression would be 3.0.
## Logical operators The logical operators, described below, compare Boolean expressions and return a Boolean result.
Operator Description and examples
And

Performs logical conjunction on two Boolean expressions. If both expressions evaluate to True, then the operator returns True; if either or both expressions evaluate to False, And returns False.

Example: =(A10>0) And (C10>0)

In this example, A10 and C10 are cell references. If A10 = 10 and C10 = 20, then the expression would evaluate to True. Alternatively, f A10 = -10 and C10 = 20, the expression would evaluate to False.
Or

Performs logical disjunction on two Boolean expressions. If either expression evaluates to True, the operation returns True; if neither expression evaluates to True, Or returns False.

Example: =(A10>0) Or (C10>0)

In this example, A10 and C10 are cell references. If A10 = 10 and C10 = 20, then the expression would evaluate to True. Alternatively, f A10 = -10 and C10 = -20, the expression would evaluate to False.
Not

Performs logical negation on a Boolean expression, yielding the opposite of the expression it evaluates. If the expression evaluates to True, the operator yields False; alternatively, if the expression evaluates to False, Not yields True.

Example: =Not (A10>C10)

In this example, A10 and C10 are cell references. If A10 is larger than C10, then the expression would evaluate to False. Alternatively, if A10 is smaller than C10, the expression would evaluate to True.
## Comparison operators These operators, described below, compare two expressions and return a Boolean value that represents the result of the comparison.
Operator Description and examples
=

Equality operator.

Example: =(A10=B10)

In this example, A10 and B10 are cell references. If the value in the A10 cell is equal to the value in C10, then the expression evaluates to True, otherwise the expression evaluates to False.
<>

Inequality operator.

Example: =(C10<>A10)

(where A10 and C10 are the links used as a formula parameters)

In this example, A10 and C10 are cell references. If the value in the A10 cell is not equal to the value in B10, then the expression evaluates to True, otherwise the expression evaluates to False.
<

The less than operator.

Example: =(@10<@12) (where @10 and @12 are the links to cells in the current column)

In this example, @10 and @12 are the links to cells in the current column. If the value in the A10 cell is not equal to the value in B10, then the expression evaluates to True, otherwise the expression evaluates to False.
>

Greater than operator.

Example: =(C10>A10) (where A10 and C10 are the links used as a formula parameters)

In this example, A10 and C10 are cell references. If the value in the A10 cell is not equal to the value in B10, then the expression evaluates to True, otherwise the expression evaluates to False.
<=

The less than or equal to operator.

Example: =(C10<=A10) (where A10 and C10 are the links used as a formula parameters)

In this example, A10 and C10 are cell references. If the value in the A10 cell is not equal to the value in B10, then the expression evaluates to True, otherwise the expression evaluates to False.
>=

The greater than or equal to operator.

Example: =(A10>=A10) (where A10 and C10 are the links used as a formula parameters)

In this example, A10 and C10 are cell references. If the value in the A10 cell is not equal to the value in B10, then the expression evaluates to True, otherwise the expression evaluates to False.
## Other operators This group includes the following operators.
Operator Description and examples
In (a binary operator)

This operator is used in an elementary logical expression that evaluates the search results and returns True when the parameter matches one of the elements from the set of values.

Example: =(A20 In (10, 50, 57)) (where A20 is the link used as a formula parameter)
True (a binary constant)

This operator is used as a parameter in logical expressions.

Example: =((D30<A30)=True) (where D30 is the link used as a formula parameter)
False (a binary constant)

This operator is used as a parameter in logical expressions.

Example: =((C10=E10)=False) (where C10 and E10 are the links to the data)
Null (a value)

This operator is used as a parameter in logical expressions.

Example: =(@20=Null) (where @20 is the cell in the current column and 10th row)
