Hey everyone.
I don’t have circular or double pointed needles so I am trying to knit a hat for my niece for her 3rd birthday using two straight needles. I am supposed to knit straight for a few inches, then start decreasing, then at the end, the yarn will be threaded through the loops of the last stitches and pulled tight to close up the top.
When it comes time to start decreasing, this is what the directions say:

the underlined parts are basically what I don’t understand.
Now, granted, I am using a different number of stitches, so it fits my niece, but I don’t understand what this is basically saying. and K1(3)? What does that mean? I know what the abbreviations mean, I just don’t get what they are indicating here. Some help would really be appreciated.
