So you got Booleans.

Actually to be precise they are not only used with numbers - they are used with finding truth in all systems having true and false statements. But in computing it's used with numbers.
Sorry for pushing on it, but actually understanding these basics benefit later and the whole world of computers stops being magic.
As to negative binary - here. But first understand binary numbers themeselves.
Ah, and now you don't need to know what equations mean. It's just a cryptic (yet precise) way to describe concepts. With time you'll probably want to know all these symbols - it's like learning a language. But now, if you know how it works, it's enough.
Glad that you like learning these things - without it's hard to explain later why certain hashes are better than others. And how they actually work.
When you finish the above the next step is entropy: Entropy_information_theory

Little humor break.
When you'll get binary you'll understand a joke that is common among IT guys.
'There are 10 kinds of people:Those who understand binary and those who don't'

The most important thing to understand is that regardless whether base is 2 or 10 all operations are actually the same. In every base multiplication, division, addition and subtraction works like with those in base 10. The reason I think everyone should know binary system is that it opens eyes to the simple fact that base does not matter in general. It matters later as some tricks are easier to perform on computer when one used 2^n base.

So, approach it with ease - it's the same as in base 10. You just have less number figures (1 and 0) to deal with.
