The issue is that the year variable is considered a string (which is used to represent text) and not an int (which is used to represent numbers) due to the fact that you have wrapped the number in quotation marks.

Quotation marks are only used when declaring a string. For pure numbers you should just write them out normally like you have done with the future variable.

So if you remove the quotation marks around the year like this:

year = 2014
puts "The year is #{year}"

future = 5
puts "In #{future} years, the year will be #{year + future}"

Then your code will work.
