conversations.value: This math problem has got me stumped: Clara brings a package of 100 stickers to school. She gives 10 stickers to a boy she likes. She gives half of the stickers which she has left to her best friends. How many stickers does Clara have left?
  Can you show me the way?

conversations.value: She gives the boy she likes 10 stickers.
  After giving the boy his stickers, she has 100 – 10 = 90 stickers left.
  She gives her best friends 90 / 2 = 45 stickers
  This leaves Clara with 90 – 45 stickers = 45 stickers.
