tsk tsk tsk... as though i'm not vexed enough abt my 2 upcoming tests for law and macro-economics...i'm now trying to figure out the answer to this question:

Alan and Bob are trying to figure out two numbers. They know that both numbers are integers between 1 and 100 (but not 1 or 100). Alan knows the product of the numbers, and Bob knows the sum. Their conversation goes as follows:
Alan: I can't tell what the two numbers are.Bob: I knew you couldn't.Alan: Ok, now I know the numbers.Bob: Now I know them, too.
What are the two numbers?

mm....if anybody can figure it out, DO let me know. Thank you!
