conversations.value: I need help with this problem:
  Anya has 4 times as many erasers as Andrea. If Andrea has 4 erasers, how many more erasers does Anya have than Andrea?
conversations.from: assistant
conversations.value: Anya has 4 x 4 = 16 erasers.
  Thus, Anya has 16 - 4 = 12 more erasers than Andrea.
