This book takes you inside the number Ten by showing the different personalities of the digits, One and Zero. All is well while working in the bank for dimes but during non-working hours there is tension between these digits. One ends up in lots of trouble because of his greed, while Zero has the job of comforting and helping him survive his 10 months sentence inside the penitentiary. Students of all elementary ages find these characters amusing, the math problems intriguing and the play on the word "Ten" surprising.
