# Code Challenge: The Math Object Task 4

I can not figure out what I am doing wrong.

"There is a variable "ageIfILiveToYear2100" already defined but it has a lot of decimal places. Create a variable named "age" and use the Math.floor method to lop off the decimal digits."

```      var diameter = 5.75,
a = 17,
b = 42,
c = 1337,
ageIfILiveToYear2100 = (new Date(2100, 0, 1) - new Date(1995, 5, 16, 7, 20)) / (1000 * 60 * 60 * 24 * 365.242);
circumference = diameter * Math.PI;
chance = Math.random() * 20;
maxWidth = Math.max(a, b, c);
age = Math.floor(ageIfLiveToYear2100);
```
