Sinopsi

Alfredo doesn?t like math and he sees no point in studying it, especially when computers are capable of resolving any problem. But one night, he encounters some aliens who can?t move their spaceship because the central computer has broken down. Unfortunately, they don?t know how to carry out the simple mathematical operation that would get the computer to work again.
