increment the variable after using its
value increment the variable and then use its new value decrement the variable after using its value decrement the variable and then use its new value |

logical (Boolean) NOT bitwise NOT (one's complement) unary minus (arithmetic negation) unary plus |
value * valuevalue / valuevalue % value |
multiplication division modulus (the remainder from a division) |
value + valuevalue - value |
