    In this instance I entered #x^2-2x-6# by using the keys in the following order.

    First I pressed the x, t, theta, n key for x.

    Next I pressed the #x^2# key.

    Next I entered a subtraction followed by 2 then the x, t, theta, n key again.

    Finally, I entered a subtraction key followed by a 6.

    Lastly, I pressed the grey "graph" button on the top right.
