conversations.value: Can you guide me through solving this problem: Tony decided he wanted to be an astronaut.  He went to college for 4 years to get a degree in science.  He then went on to get 2 more degrees in other fields for the same period of time.  He also got a graduate degree in physics, which took another 2 years.  How many years in total did Tony go to school to be an astronaut?

conversations.value: Tony got 3 degrees which each took 4 years, for 3*4=12 years spent.
  He then got his graduate degree, which was another 2 years added to the previous total, for 12+2=14 years in total.
