@raggaemuffin I'm not sure what you are asking us to code here. We take a string that is a polynomial, change it to a math code, and then return the same string we started with? Are we factoring, simplifying, solving, or plugging in a solution value for x?

I understand it like this:

you get a polynomial (like described) and parse it.
implement functions 'add', 'subtract', ... etc.
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 :)
