I believe this is a “typo” but I am too new to post this under bug.

" Notice that basketTotal = spinachPrice + basketTotal and basketTotal += spinachPrice do the same thing!"

It might be slightly semantically nitpick-y, but basketTotal += spinachPrice is actually basketTotal = basketTotal + spinachPrice and not basketTotal = spinachPrice + basketTotal.

The only reason why the above statement holds is because integer addition is commutative which it was talking about, but in the segment right after the course started talking about string concatenation, and not making this important distinction might cause new programmers to be confused on why "cat" += "dog" is not "dogcat" but is "catdog".
