Poor student studying for a scholarship exam in a week!!

I want to know how (as simply as possible) to insert objects into a
linked list.

Example question:

"Define a linked list that can represent a polynomial.  Then write  a
method to add on another polynomial (ie link them) to the current one,
and a method to add the one polynomial to another."

Now I know how to define the linked list - a class that has an exponent
and a coefficient and a pointer to objects of that class, and I know how
to create the list.  I also know that to add on another linked list to
the current one you just traverse the first list and then set its end
pointer to the pointer to the start of the second list.
     But how do you do the add method?  the exponent term of one may be
different to that of the other and in that case it will have to be
inserted somehow??
eg. (3x^2 +2x^5) + (2x + x^3+x^5) = 2x+3x^2+x^3+3x^5

I am so grateful to you if you can reply to me at
