Help with a pattern

I am attemping to knit a swearter for the first time and I have run into part of the pattern I don’t understand. The instructions are… (WS). Purl, dec 14 sts evenly across. 90 sts. I understand about the wrong side and decrease 14 stiches evenly across, but I don’t understand what it means by 90 stiches. Can someone help me, please. Lost in NC.

The number at the end of the instruction is telling you how many sts you will have after you finish the row. You’ll have 90sts left after the decrease of 14sts…
Good luck with the first sweater (always an adventure)!
