(e^2 - 2e -1)/e

Explanation:

First, let's discuss e^1 and e^-1

e^1 just means e
e^-1 means 1/e
[If there was e^-2 it would have meant 1/e^2]

So now it becomes really simple.

Also (-1)^3 = -1
[-1 raised to any odd number is -1 and if it is raised to any even number, it is 1]

Let's solve this

(e-1/3) - (1/e +1/3)
e-1/3-1/e-1/3

This becomes (3e^2 - 2e -3)/(3e)
