# Arithmetic Operators

With the arithmetical operators you perform mathematical calculations (basic arithmetic operations).

Please note that for arithmetic operators the well-known processing hierarchy "point before dash calculation" applies.

First the operator 'Modulo' is evaluated, then multiplication and division ("\*" and "/"), and finaly addition and subtraction ("+" and "-"). If you want a different processing sequence you must use brackets. The 'innermost' brackets are always evaluated first.

The Formula Editor provides the following arithmetic operators:

| Operator | Meaning                           | Data types               |
| -------- | --------------------------------- | ------------------------ |
| +        | [Addition](#addition)             | NUMBER, DATETIME, STRING |
| -        | [Subtraction](#subtraktion)       | NUMBER, DATETIME         |
| \*       | [Multiplication](#multiplikation) | NUMBER                   |
| /        | [Division](#division)             | NUMBER                   |
| %        | [Modulo](#modulo)                 | NUMBER                   |

Please note that the arithmetic operators are evaluated in the well-known 'point before line' hierarchy. An expression is executed in the order Modulo operator (%), multiplication/division (\*,/) and lastly addition/subtraction (+,-).

If you want to bypass this order you must use brackets. The levels of brackets are then evaluated from inside to outside.
