Continued fraction

Continued fractions are when you use fractions inside of other fractions. For example, let's say you want to make a fraction like 3/2. But instead of just writing that, you can write it as a continued fraction by writing it as 1 + 1/(1+1/2). That just means the same thing, but the whole number part is shown first, then the fraction part.
