| 1 | New expression | new <typename> |
| 1 | Array subscripting | <array>[<index>] |
| 1 | Member access | <object>.<member> |
| 1 | Function-like call | <func>(<args...>) |
| 1 | Parentheses | (<statement>) |
| 2 | Prefix increment and decrement | ++, -- |
| 2 | Unary plus and minus | +, - |
| 2 | Unary operations | delete |
| 2 | Logical NOT | ! |
| 2 | Bitwise NOT | ~ |
| 3 | Exponentiation | ** |
| 4 | Multiplication, division and modulo | *, /, % |
| 5 | Addition and subtraction | +, - |
| 6 | Bitwise shift operators | <<, >> |
| 7 | Bitwise AND | & |

| 9 | Bitwise OR | | |
| 10 | Inequality operators | <, >, <=, >= |
| 11 | Equality operators | ==, != |
| 12 | Logical AND | && |
| 13 | Logical OR | || |
