Let p: the integer has one digit. let q: the integer is less than 10. which represents "the integer has one digit if and only if the integer is less than 10”? p ∨ q p ∧ q p → q p ↔ q

The double implication "if and only if" is graphically represented by an arrow pointing in both direction, so the correct writing is

4400
