conversations.value: I'm completely lost with this math problem: Jane bought 2 skirts for $13 each. She also bought 3 blouses for $6 each. She paid the cashier $100. How much change did she receive?
  Can you give me a hand?

conversations.value: The 2 skirts cost $13 x 2 = $26.
  The 3 blouses cost $6 x 3 = $18.
  The total cost for 2 skirts and 3 blouses is $26 + $18 = $44.
  Jane received $100 - $44 = $56 change.
