What I saw first:
All the same except:
#8--13+6=19
#11--I'm assuming the problem was Supposed to be--10-8=3. Then moving 1, 10-8=2. Or maybe you meant Move *2.
#14--8-0=8
#15--vice versa--8+6=14
#17--15+3=18
#18--vice versa--5+6=11
Bonus--2111

Also works:
#2. 15-6=9
#8. 13+6=19
#15. 8+6=14
#16. 13-16=-3
#17. 15+3=18
#18. 5+6=11

🤔 These also work 🧐
on #2 -- 15-6=9
on #8 -- 13+6=19
#11 was chicanery 🧐 one stick altered, one stick moved
on #15 -- 8+6=14
on #18 -- 5+6=11 (why change BOTH addends? just one will do the trick)
🤓 Bonus baby is 1211 (one stick? fuhgettaboudit)😎
