conversations.value: Find the answer to the math problem: Tyler has $100. If he buys 8 scissors for $5 each and 10 erasers for $4 each, how much of his money remains?
conversations.from: assistant
conversations.value: 8 * $5 = $40 is the price of 8 scissors.
  10 * $4 = $40 is the price of 10 erasers.
  You can find the total price by adding the cost of the scissors and erasers: $40 + $40 = $80
  $100 - $80 = $20 is the remaining amount of his money.
