conversations.value: I would love to understand how to solve this problem: Davida worked 35 hours on each of Weeks 1 and 2. She worked 48 hours each of Weeks 3 and 4. How many more hours did Davida work on Weeks 3 and 4 than on Weeks 1 and 2?
  Can you explain?

conversations.value: Week 1 + Week 2 = 35 + 35 = 70 hours
  Week 3 + Week 4 = 48 + 48 = 96 hours
  Subtract Weeks 3-4 from Weeks 1-2 = 96 - 70 = 26
