Prime tutorial buggy
I started to go through the tutorial in Prime 3.0 and found a couple of bugs right off the bat. Then I looked back at Prime 2.0 and it has the same error. It says that the exponentiation operator is x^n. But it really is listed as x^y. I know it isn't a big deal but it is sloppy. Also, exercise 2-1 is written sloppily and if a user follows the steps verbatim, the user will have an error.
Come on, PTC, get your act together!
