I'm a newbie to all puzzles, so please be nice when you explain this to me. smile I read the starting tips for Figure Logic 2 in July 2013 issue of Math and Logic Problems, but I still can't see the obvious of Linda Thistle's starting tip answers. As it stands in the answer chart, Clue for 2-Down (2 digits) "is nine times 13-Across." 13-Across (2 digits) is "One less than 31-Down" and 31-Down is two digits. According to the answer key, the answer for 31-Down is "12." The answer for 13-Across was "11." The answer for 2-Down was "99".

So here's my question... Couldn't 31-Down have been "11" (not just the 12). Couldn't 13-Across been "10." And Couldn't 2-Down been "90"? How do I use logic and math when it initially appears there are more than two possible answers? Could you please explain how I would have known for sure that it was 12 (not 11) in 31-Down? I am missing something.

Thank you for your help! Please give step by step on the formulas and algebra if possible.

Hi Texan and welcome to the forum! smile I have this magazine and think I can help. The only possibility for 13 Across is 11. It's true that 10 can fit the math of 10x9 and still be a 2 digit number (90), but if you were to place the answer 10 into 13 Across, 14 Down would begin with a "0" and you can't have a zero as the starting number in this puzzle.
