I think this might be a typo.
The end of the first paragraph states:
Later in this chapter, you'll redefine the add: method so that add: does not affect the value of its argument.

Instead of saying "argument" at the end, it should say the receiver?  I'm not 100% sure, but thought I'd ask.

thanks,

Thanks Geoff, that's a good catch!
