Usually stuff in brackets is there because there's more than one size the pattern offers. The smallest size is outside the brackets, with the first one in the brackets being medium, next large, etc. Likewise, if they used numbered sizes, it's the same, only the small may be a size 5, the medium a 7 and the large a 9... the only time you would do repeats is if there's stuff in parenthesis... it would go like this: (k2, p1, m1) three times, k5. That's how they show that you have to repeat something (that's not actually from a pattern, just randomly made up for an example). Check near the top of the pattern... I bet it has a small, medium and large size somewhere around where it lists the stuff you need.
