Look, the first one is 25 plus 15, and the second one is 25 plus 5 1. The first place is 50, 1, and the second place is well done, 15. The digits are reversed, 1 ten digits, 5.

I found that every number on it was upside down.

One place becomes ten. .

Thank you. No, asking questions is not easy. Thank you.
