First Spanish Reader 7. ANOTHER
MATHEMATICAL FIASCO: DIFFERENTIAL CALCULUS A man buys four
handsome donkeys in a fair. He mounts one of them and returns to his house.
On the way he counts his donkeys: one, two, and three. He counts them again: one,
two, and three. He forgets to count the one he is riding. He arrives at his
house and tells his wife: “I have just bought four handsome donkeys in the
market place this morning and now I discover only three.” His wife stares at
him amazed and replies: “How strange! You see only three while I see five.” |
