Thinkboard Week 7

I am again back with more Think boards, this time it got tricky. We had to figure out what 12.5-:-0.5 is. Something I learnt is that 12.5 is over 0.5 times 10 and even 20 so it must have been between 20 and 30. I soon figured out the answer witch was 25. Hope you enjoy and please leave a comment.
