I try to understand why by definition

$[c0,c1,...cn]=[c0,[c1,...cn]]$ and also

$[c0,c1,...cn]=[c0,c1,...c(n-2),[c(n-1),cn]]$ .

But not

$[c0,c1,...cn]=[c0,c1,[c2,...cn]]$ for example.

I presume that your "[c0, c1, ..., cn]" means the continued fraction . It should be clear that you can factor out that top "c0" to get which is your "[c0, [c1, ..., cn]]".

Try doing that with n= 2 or 3 to see what is happening.
