How do I interpret the instructions
I’m attempting to knit a sweater. Started out casting on 83 stitches and completed ribbing. Stuck understanding the next instructions: Next row (RS): K2, K2tog, K to last 4 sts, K2tog tbl, K2. Working all decreases 2 sts in from ends of rows as set by last row, cont in st st, shaping side seams by dec 1 st at each end of every foll 10th row to 73 (77: 83: 87: 93) sts.
