| Yay! First comment! Interesting quiz. |

| obviously if you open to a pair of pages, you are correct - sum is odd, product is even. But what if I choose page 11 and page 15. Sum = 26, Product = 165. Wouldn't that mean it depends? Or did I miss something? |

| I think the assumption is that it means 2 adjacent pages. |

| Yes. It's like a real book. Use adjacent pages. |

| Why is the sum never 15? Have you ever tried to hide cash between pages 7 and 8 of a book? |

| Prove: The sum of any odd number and any even number is odd.
Proof:
Let 2n+1 represent the odd number and 2m the even number, where m and n are positive integers. Thus, 2m + (2n+1) = (2m+2n)+1 = 2(m+n) +1 , which is odd.
Prove: The product of any even number and any odd number is even.
Proof:
Let 2m represent the even number and 2n+1 be the odd number, where m and n are positive integers. Then the product 2m(2n+1) = 2(2mn + m), which is even. |

| I thought opening to two different pages meant to take the sum and product of the four pages. In this case the product is stop even but now so is the sum.
Poorly worded. :x |
