#8...... 9-0=9

Erm, if you change the numbers, then by definition, it's not strictly the same equation...is it?

Yes. I guess the instruction should instead state something like, "Move 1 stick to make an equation."

Again, I solved the thumbnail and I got a 15/15. Alternates: 8. 9-0=9

#8, 9-9=0

Or 9-0=9

4十3=7

9-6=3

3=6-3

6+3

4+3

#11: 1 - 5 = -4

4+3=7

6+3=9

First one. -4 + 5 = 1. Take 7s flag and move it in front of the 4

2十2=4

3十0=3

if AI can solve this on it's own, then it's coming along well

6+3=9
