| Operator | Operation | Result | Description |

| == | A == B | false | Check if two numbers are equal, if yes then true, otherwise false |
| != | A != B | true | Check if two numbers are not equal, if yes then true, otherwise false |
| > | A > B | true | Check if left side is greater than right side, if yes then true, otherwise false |
| < | A < B | false | Check if left side is less than right side, if yes then true, otherwise false |
| >= | A >= B | true | Check if left side is greater than or equal to right side, if yes then true, otherwise false |
| <= | A <= B | false | Check if left side is less than or equal to right side, if yes then true, otherwise false |
| Operator | Operation | Result | Description |
|---|
| && | A && B | false | If both sides are true, then true, otherwise false |
| != | A != B | true | If either side is true, then true, if both sides are false, then false |
| ! | !A | false | If the condition is true, then false, otherwise true |
