conversations.value: I would love to understand how to solve this problem: Thomas is 6 years old. His older sister, Shay, is 13 years older than him and 5 years younger than their older brother, James. How old will James be by the time Thomas reaches his current age?
  Can you explain?

conversations.value: Shay is 6 + 13 = 19 years old.
  James is 19 + 5 = 24 years old.
  Thomas will be 24 in 24 - 6 = 18 years.
  James will be 24 + 18 = 42 years old.
