    I understand it like this:

    1. you get a polynomial (like described) and parse it.
    2. implement functions 'add', 'subtract', ... etc.
    3. implement toString() method (to see the result of implemented operations).

    Am I correct on this one?

      So, does it come with a second input to plug in for x, then?

        @bandli is correct. You get a string representation of a polynomial and should implement a class that parses that and allows to fo math with it:

        a = Polynomial('3x^2')
b = Polynomial('5x^4')
c = a.multiply(b)
c.toString => '15x^6'

        If you want to have an evaluate method that could be fun too

          It might help a lot if you have one or two examples like this in your post, so we can include them in our test cases. It makes understanding the problem at hand a bit easier. In the real world I would say "specifications unclear" and send it back to the Product Owner ;)

          You are right! I wanted to post it and probably should have refined the specification a bit before that. Next challenge I'll see to make up to that

            Oh! You want us to create a polynomial class and return an object of that given polynomial! Is that it?

              I want you to create a polynomial class that has a constructor accepting a string :)
