What is the practical difference between unos and algunos?

Question

I am very confused about the difference between unos(unas) and algunos(algunas). Is there an easy way to remember?

Answer 1

I think of unos as "a few".

Algunos means "some".

I like to remember that unos is probably less than algunos because "uno" is only 1, so unos is not that far from it.

Meanwhile, "some" is rather relative to circumstances, so in some situations, "some" could be 10 or 20, while a "few" is usually 2 to 5 or so.
