Arithmetic expressions are simple expressions built with arithmetic operators and constants or references to cells. *Operands* are the values upon which the operator acts. There are two types of arithmetic operators:

*Unary*operators that act upon just one element; using only one operand located on the right of the operator. For example:=

**-**A6*Binary*operators that act upon two elements (using two operands, one located on either side of the operator). For example:=B4

**+**A6

Arithmetic operators are as follows:

Operator | Name | Type | Description |
---|---|---|---|

+ | Addition Operator | Binary | Adds two values |

- | Subtraction operator | Binary | Subtracts two values |

- | Inversion Operator | Unary | Gives the opposite value of a value |

* | Multiplication operator | Binary | Multiplies two values |

/ | Division operator | Binary | Divides two values |

^ | Power operator | Binary | Multiplies the left operand to the specified power shown by the right operand |

% | Modulo operator | Binary | Gives the remainder of the whole division of two numbers |

Arithmetic operators are used in a predefined order or priority. To modify the predefined priority, parenthesis must be used. Here is a table that shows the priority of the operators:

Operator Priority | ||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|

++++++ | () | |||||||||||

+++++ | % | |||||||||||

++++ | ^ | |||||||||||

+++ | - | |||||||||||

++ | * | / | ||||||||||

+ | + | - |

When two operators have the same priority, the calculation is performed from left to right.
