I haven't done this in a while, so I might be wrong

1. If a number is even then it is divisible by 2

2. any even number is divisible by 2

3. if the number is divisible by 2, then it is even. this converse is true

4. if a number is even, it is divisible by 2. this inverse is true

5. if the number isn't divisible by 2, then it isn't even

6. if a number is even then it is divisible by 2 and only if the number is divisible by 2, will it be even

7. If a number is odd, then it isn't divisible by 2.

converse: if the number isn't divisible by 2, it is only sometimes odd. (idk)
