conversations.value: This math problem has got me stumped: Andy has 4 times as many white socks as he has black socks. If he loses half his white socks, how many more white socks does he still have than black socks if he has 6 black socks?
  Can you show me the way?

conversations.value: Andy has 6 x 4 = 24 white socks.
  He loses 24/2 = 12 white socks.
  He still has 12 - 6 = 6 white socks more than black socks.
