Question

So if a number is divisible by 2, then the number is even.

Is this biconditional or is there a counterexample?

Answer 1

No cuz if a number is dividable by 2 then it's even if the number is not even then it is not dividable by 2.

Answer 2

Biconditional means they can both be the hypothesis and the conclusion.

If a number is divisible by 2, then the number is even. TRUE

If a number is even, then it is divisible by 2. TRUE

Since both statements are true, then it is a biconditional statement.

Answer: Biconditional
