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

Courses Plus Student 2,448 Pointsvar 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.
