Four children, A, B, C, and D, are playing a game with playing cards that involves computations using numbers. They shuffle the cards from Ace to Nine of hearts and stack them up. Each person draws two cards and then states the relationship between the two numbers. Child A says the sum of the two cards in their hand is 10. Child B says the difference between the two cards in their hand is 1. Child C says the product of the two cards in their hand is 24. Child D says the quotient of the two cards in their hand is 3. Based on this information, guess the number on the remaining card that nobody has drawn.
