| ## Description |
| |
| Operator precedence determines the order in which operators are evaluated in an expression. When an expression contains multiple operators, Doris will perform calculations in descending order of operator precedence. |
| |
| ## Operator Precedence |
| |
| The precedence decreases from top to bottom, with the highest precedence at the top. |
