- We pick four numbers from 1 - 10.
- Then we call 2 perfect logicians called Ann and Bob. They know we have four numbers but neither of them know the numbers.
- We add those numbers and tell only Ann the result.
- We multiply those numbers and tell only Bob the result.
- Then we put them in a room together and ask them how many numbers do they know from the addition and multiplication of the numbers:
- Ann: I don't know any number
- Bob: I only know one number
- Ann: I now know two numbers
- Bob: I now know all the numbers!
- What are the numbers?
