What's up!

You are sort of on the right track, but you have a few issues.

First, let's look at the first challenge: Create a variable named years. Assign years to the number of years old you are.

You successfully completed this with the code: 

years = 30

The second challenge says multiply the number years by the number of days in a year.. Here, we can assume the number of days in a year is 365.

In Python, we use the * to multiply, not x like most people write when doing Math at school. Python's syntax for multiplication is as follows: "<number> * <number>", where "<number>" could be an integer (like 30), a decimal (like 3.5), or a variable (like years).

This would mean:

years = 30

print( years * 365 )

Would print out 10950. Python knows that the word "years" really means 30. From there it says "Okay, 30 times 365 is 10950. The last part of challenge 2 is to store this result in a variable called days. So instead of printing out our result, lets assign it to the word "days":

years = 30

days = years * 365

I hope this clears up your question! If not, please leave a comment to this about anything you may not be clear about and I will try my best to clear it up or someone else may come along and be able to explain it better :)

Thanks!
