I recently picked up a book on biomathematics and was sort of introduced (actually, more or less I was assumed to be familiar with) difference equations.(adsbygoogle = window.adsbygoogle || []).push({});

Now, to me it seems that they are just a discrete version of differential equations, treating the inpendent variable as a discrete integer, leading to some sort of recursive series (which makes sense, especially considering population growth models, as a fractional time will lead to fractional populations). Seems pretty simple, but I was wondering if anybody could lead me to a good introduction of the subject.
