Start with the Strings section and the Extract the money exercise linked in the issue, then compare its unary + usage with the MDN reference. Add a concise explanation of the unary plus operator where it fits in the tutorial, including how it applies to the shown solution.

Description
The solution to Extract the money problem, uses the unary + operator, however, I don't see that explained anywhere in the Strings section. Adding an explanation of that would be helpful.
