conversations.value: Explain how to solve this math problem: Three siblings are born 5 years apart, each. If the eldest child is 20 years old now, what's the total of the ages of the three siblings 10 years from now?
conversations.from: assistant
conversations.value: Ten years from now, the elder child will be 20+10 = 30 years old.
  If the elder child is 20 years old now, the second born is 20-5 = 15 years old, 5 years younger than the firstborn.
  The second-born will be 15+10 = 25 years old ten years from now.
  The total age of the first and second-born 10 years from now will be 25+30 = 55
  The third-born who is five years younger than the second born is 15-5 = 10 years old.
  The third sibling's age ten years from now will be 10+10 = 20 years old.
  The total age of the three siblings ten years from now will be 55+20 = 75 years.
