conversations.value: Josh has 18 yards of ribbon that is to be used equally to 6 gifts. If each gift will use 2 yards of ribbon, how many yards of ribbon will be left?
  Can you solve this problem?

conversations.value: The 6 gifts will use 6 x 2 = 12 yards of ribbon.
  So, 18 - 12 = 6 yards of ribbon will be left.
