conversations.value: Can you explain how to solve this math problem: Cindy was 5 years old.  Her sister Jan was 2 years older than Cindy.  Their oldest sister Marcia was twice as old as Jan.  Greg was two years older than Marcia.  How old was Greg?

conversations.value: Jan was 2 years older than Cindy who was 5 so 2+5 = 7 years old
  Marica was twice as old as Jan so 2*7 = 14 years old
  Greg was 2 years older than Marcia who was 14 so 2+14 = 16 years old
