question: Caroline has 4 children.  The first child is 6 feet tall.  The second child is two inches taller than the first child.  The third child is 5 inches shorter than the second child.  And the fourth child is three inches taller than the third child.  How tall is the fourth child, in inches?
answer: The six-foot-tall first child is 12*6=<<6*12=72>>72 inches tall.
  The second child is two inches taller than the first child, or 72+2=<<72+2=74>>74 inches tall.
  The third child is 5 inches shorter than the second child, or 74-5=<<74-5=69>>69 inches tall.
  And the fourth child is three inches taller than the third child, or 69+3=<<69+3=72>>72 inches tall.
