Introduction
Order of operations, also called operator precedence, is a set of rules specifying which procedures should be performed first in a mathematical expression.
Precedence Overview
| Precedence | Type of Operator | Examples |
|---|---|---|
| 11 |
Nular operators (commands with no arguments):
|
|
| 10 |
Unary operators (commands with 1 argument):
|
|
| 9 | Hash-select operator | |
| 8 | Power operator | |
| 7 | ||
| 6 | ||
| 5 | N/A | |
| 4 |
Binary operators (commands with 2 arguments):
|
|
| 3 | ||
| 2 | Logical and operator | |
| 1 | Logical or operator |
