      The JavaScript Math object has the following
      constant (among others):
      Math.PI
          Approximately 3.14159. Pi (π) is used
          to determine the circumference of a circle
          given its diameter by multiplying the diameter
          by π. Geometery refresher: the circumference
          of a circle is the distance around the outside
          edge. The diameter is the width of the circle.

      The JavaScript Math object also has the following
      methods (among others):
      Math.random()
          Returns a random number between 0 and 1
      Math.max(a, b, ...)
          Returns the largest value of the passed
          arguments
      Math.floor(a)
          Returns the value of a number rounded down to
          the nearest integer

var age = Math.floor(ageIfLiveToYear2100);

  • I think that you forgot to put the letter "I" in the ageIfLiveToYear2100. It should be "ageIfILiveToYear2100" (ageIf"I"LiveToYear2100 ).

Let me know if that helped.
