well in the second part of the code challenge all it is asking you is to assign an NSNumber literal with a value of 4 to the variable thing.

So basically whatever variable you have which is the name of the NSNumber, make sure you assign it the number four. But since the term literal is there, it means use the short hand.

For example, for NSNumber the literal short hand is the @ sign. so you would use @4 and assign that to the the variable thing as an NSNumber literal.

hope that helps!!
