Knitting sweater, binding off question

I’m knitting a sweater and I’m starting on the shoulder/neck area. I have to bind off 10sts to start, I know how to bind off, my question is, when I knit the 10th stitch am I taking the 9th pulling it over the 10th then continuing the rest of the pattern, or am I knitting the 11th stitch and pulling the 10th over it then continuing the pattern

It’s the latter–the 10th stitch also is bound off. You should end up with 10 fewer stitches in that row than you started with.

Thank you!
