title: How to store a polynomial?
body: <p>Integers can be used to store individual numbers, but not mathematical expressions. For example, lets say I have the expression:</p>
  
  <blockquote>
    <p>6x^2 + 5x + 3</p>
  </blockquote>
  
  <p>How would I store the polynomial? I could create my own object, but I don't see how I could represent the polynomial through member data. I do not want to create a function to evaluate a passed in argument because I do not only need to evaluate it, but also need to manipulate the expression.</p>
  
  <p><strong>Is a vector my only option or is there a more apt solution?</strong> </p>
