conversations.value: I'm completely lost with this math problem: Jackson and Brandon both invest $500 in the stock market. Jackson's investment quadruples in value, while Brandon's is reduced to 20% of the initial value. How much more money does Jackson have than Brandon now?
  Can you give me a hand?

conversations.value: First find the end value of Jackson's investment: $500 * 4 = $2000
  Then find the end value of Brandon's investment: 20% * $500 = $100
  Then subtract the value of Brandon's investment from the value of Jackson's investment to find the difference: $2000 - $100 = $1900
