Hi I really hopes this helps. So from what I understand your asking for 11 times 12 divided by 15. So, 11 times 12=132 and 132 divided by 15 is 8.8 if you round then 9.

If you do a neck stretch, you can do a type of stretch on the right side of your head and then you could do that same type of stretch on the left side. And for the calf stretch you can do calf raises with your toes pointing in and out they give a different stretch too.
