The implies relation, denoted A⟹B or B⟸A where A and B are statements of some sort means:
| A | B | A⟹B | A | B | A⟹B |
|---|---|---|---|---|---|
| false | false | true | T | ||
| false | true | true | T | T | |
| true | false | false | T | ||
| true | true | true | T | T | T |
Note: it is only not true that A⟹B when we have A but not B
