conversations.value: Greg is riding his bike around town and notices that each block he rides, his wheels rotate 200 times. He's now on a a trail and wants to make sure he rides at least 8 blocks. His wheels have already rotated 600 times, how many more times do they need to rotate to reach his goal?
  Solve this problem.

conversations.value: They need to rotate 1,600 times because 8 x 200 = 1,600
  They need to rotate 1,000 more times because 1,600 - 600 = 1,000
