Pattern help

I am making a baby sweater and am unsure of what they mean by this:
Row 1: K1, (P1,K1) across
Do I do the whole thing till the rows complete or just whats in parantheses?

i usually take it to mean the parenthesis are the repeated to the end bit. What is row 2? Does it name the stitch pattern you are doing for the sweater?

in this case,

you would do your k1 first
and then repeat what is in the paren until you are all the way across.

sometimes it looks like you had sometimes it is in * * and you repeat what’s in the middle.
