Simple Maths

A mathematician, a biologist and an engineer were sitting in a bar and had been for four days. All this time, they were observing a building across the street. On the fifth day, they agreed that the building was empty. On the sixth day, they observed two people entering the building in the morning and three people exiting the building in the afternoon.

"Aha!", exclaimed the engineer, "the building was never truly empty!"

The biologist said, "No, no - they must have procreated."

The mathematician pondered the situation. He slowly said, "If one more person enters the building, then it will be empty."
