conversations.value: Can you walk me through the solution of: John builds a toy bridge to support various weights.  It needs to support 6 cans of soda that have 12 ounces of soda.  The cans weigh 2 ounces empty.  He then also adds 2 more empty cans.  How much weight must the bridge hold up?
conversations.from: assistant
conversations.value: The weight of soda was 6*12=72 ounces
  It had to support the weight of 6+2=8 empty cans
  The weight of the empty cans is 8*2=16 ounces
  So it must support 72+16=88 ounces
