conversations.value: Sid takes $48 with him on a shopping trip to the mall.  He spent some of his money on computer accessories and another $8 on snacks. After these purchases, he only has $4 more than half of his original money left. How much did he spend on computer accessories?
  Give me a solution to this problem

conversations.value: Half of Sid's original money is $48/2 = $24.
  Sid has only $24 + $4 = $28 left after his purchases.
  He had $28 + $8 = $36 before he spent $8 on snacks.
  So, Sid spent $48 - $36 = $12 on computer accessories.
