Eating at the dining table, and testing Dominic's ability to do maths in his head.

Daddy: Dominic, if a box of cornflakes costs $3.00, and you have $10.00, how many boxes of cornflakes can you buy?

Dominic: (after thinking) Three.

Daddy: That's right.

Dominic: (seriously) Daddy, if one box of vegetables cost $10.00 and each vegetable costs 59 cents and you have one million thousand eighty-five twenty two dollars, how much money do you need to buy five hundred thirty three boxes?
