conversations.value: I would love to understand how to solve this problem: $18 is shared among 3 boys. The eldest added $5 to his share and added another $10 the following day. He later needed some money and spent $8 from his total so far. After saving some more, he was able to triple the amount he had left after spending the $8. How much does he have now?
  Can you explain?

conversations.value: Each boy gets $18/3 = $6.
  The eldest had $5+$6=$11 after adding $5 to his share.
  He added another $10 so he had $11+$10=$21.
  Then he had $21-$8=$13 after spending $8.
  So, he now has $13*3=$39.
