Why did you use 1.0 and 3.0 instead of just 3 and 1 though?

Because 1 / 3 = 0 (due to integer <strike>rounding</strike> truncation)
I guess I could have just used 1 / n and had n be 3.0 or used 1.0 / n and just had n be an integer, but if you have both n = 3 and 1 / n, then the parens part will turn out to be 0 each iteration.
Edit: changed rounding to truncation to be more accurate about what the comp does.

ahh so putting that .0 there is just telling it not to round off right?

Hm yeah basically.
In operations involving integers, the result will be an int (so if there is some remainder, it just gets cut off). If you make one of them not an int, then the result won't be an int.

This sounds like a terrible way to learn programming, and I've never had to know VBA anywhere -0-
It depends upon what sort of job you are going into, I guess.

Well, I would expect to find MS Excel nearly everywhere (actually not that obvious, sometimes they cut the costs..), while in order to use any other language you need some sort of compilator. If you work on any important data, you probably cant access the internet, nor use a pendrive too - so you wont be able to download it.

perhaps you are a programmer

after I've seen an insurance company working on an acesss database I lost all faith anyway..

No idea, as I've never learned Python, and I never used a textbook when learning Java.
One of the lecturers who teaches intro to programming at my university wrote a book, I can't say anything about the quality of it not having read it, however.

[those are the pre-release chapters, if you want the latest version you have to shell out money, I think]
edit: shit, just noticed the links are dead on that page, lol

this one works, though
