puzzles

Hi do we have any maths people here questions 2 and 3 doing my nuts as kids won't leave me alone until I solve A Sneaky HELP

I always liked these little puzzles and thought it would be nice starting a thread with this one: He who makes me doesn't want me, He who buys me doesn't need me, He who uses me doesn't care. What am I?

don't know if we've done this one here before, but it's worth another look a game called "Petals Around The Rose" http://www.enc.org/features/focus/archive/inquiry/document.shtm?input=FOC-000711-index and a nice automated version http://www.freeworldgroup.com/games/roses/...
