conversations.value: Her hair was 24" long and she cut half off so she cut 24/2 = 12 inches
  Her hair was 24" long and she cut 12" off so she has 24-12 = 12 inches left
  She has 12" of hair and lets it grow 4 more inches for a total of 12+4 = 16 inches
  She has 16" and cuts off 2 more inches which leaves her hair 16-2 = 14 inches long
