The k0 means there is no stitch to knit for your size so you can skip that. I've deleted it in the row:
[k2tog) 5(6:7) times,k1,ssk,yo,k5,k2tog,yo.k4,yo,ssk,k3,ssk,yo,k3,(k2tog) 5 times. 34 sts.
34sts tells you the total number of sts you'll have when you finish the row. The row before this should have 44sts and since your net decrease is 10sts, you'll finish the row with 34sts.
The Details: the pattern begins the ends with k2tog repeated 5 times at each end so that gives you the decrease of 10sts. There are 4 decreases in the central part of the pattern, ssk or k2tog but these have a yo to increase for each and so there's no change in the st number. If you'd like to see a video of the yo, which happens between sts, go to the Free Videos, Increases page. For the ssk or k2tog, see Decreases.
Welcome to KH! Glad to have your here.
