conversations.value: Can you break down the solution for me for this math problem: Martha has been collecting shells since she turned 5 years old, every month she collects one shell. By her 10th birthday, how many shells will Martha have collected?
conversations.from: assistant
conversations.value: In 12 months of the year, Martha collects 12 * 1 = 12 shells.
  From her 5th to her 10th birthday, 10 - 5 = 5 years have passed.
  During the 5 years that have passed, Martha has collected 12 * 5 = 60 shells.
