A physicist, a biologist, and a mathematician are all observing a small house one day. At one point, they see two people enter the house. A short while later, three people come out.

"It appears that my initial observations were flawed," the physicist admits ruefully.

"Now, now," the biologist says, trying to comfort his friend. "Clearly, the two must have reproduced."

The mathematician has his own elegant explanation. "If one more person enters the house," he says, "then there will be no one in the house."

2 in, 3 out

2-3= -1

1 goes in
1+ -1= 0
