I was torn between A and C but I didn't do it mathematically: I
   just set the three glasses of juice on a table in my mind and
   saw which glass had the most room left and which one the least.
   I was torn between A and C. So A or C. The person who got B
   would get less juice. [1]#howmybrainworks [2]fazsd In this
   scenario, there's two kids with juice (or two picky adults with
   glasses of wine), and I have to quickly decide who gets what.
   I'd give each of them A and C, and I'd take B for myself 'cause
   I hate ppl complaining about things being unfair. They can
   bicker over A and C if they want. I'm just thirsty and I know I
   didn't take the lion's share. ==== I did this in school too.
   Some math teachers LOVED and some HATED that I turned things
   into stories and usually solved for estimates (unless the answer
   'popped up' in my head right away), but lemme tell ya - I'm 43
   yrs old going on 44, and the ability to quickly estimate "close
   enoughs" is far more a sanity-saver than anything. [the
   precision wasn't hard either but I like speed and accuracy] I
   also hated "show your work". My poor 10 yr old nephew's was
   going through "show your work" stuff himself and I taught him
   how to keep doing it in his head the way he's good at, and then
   ALSO showing work the way the teacher wants on paper. 4th grade
   he was on the verge of failing math because he's good at it in
   his head, like I was/am - makes everything into stories that
   make sense to him. Told him WHY teachers need "show your work"
   _more_ than the answers. He was annoyed at the school system for
   that (like I was at his age) but his grades shot back up. So
   far, he's surviving Common Core ok smile emoticon In short, he
   just has to do things twice now. 1st get the right answer (or
   close enough) in his head, 2nd, show-your-work the way the
   teacher wants to see it. It works smile emoticon Good brain
   challenge btw - thank you smile emoticon
