Re: BRAIN TEASERS THREAD
if the numbers were (3,4), then mr. add would see 7 and know that mr. multiply is seeing either 10 or 12. if he were seeing 10, he would know the numbers are 5,2 so he must be seeing 12. given that its 12, mr. multiply doens't know if its 6,2 or 3,4.
mr. multiply is seeing 12. he knows that it's either 6,2 or 3,4. if it were 6,2, mr add would be seeing 8 and would think its 2,6...3,5...or 4,4.
...(insert more complicated thoughts?!)...
therefore, mr. multiply knows it is not 6,2. thus he knows the numbers are 3,4. and once he figures that out, mr. add knows it's 3,4 also.
lol i thought i had it but the he thinks-i think-he thinks progession got too complicated. i think i might have the right answer though. i think A and B have to be between 1 and 10, and that OP said 1-100 to throw us off. i don't think multiplying numbers greater than 10 allow for this type of situation to be feasible.
then again, this is all speculation because i'm not smart enough to figure it out.
