How does the 8 9 trick work?

The "8 9 trick" usually refers to the finger trick for multiplying by nine, where you number fingers 1-10, fold down the finger for the multiplier (e.g., the 8th finger for 9x8), and the fingers to the left (7) become the tens digit and fingers to the right (2) become the ones digit, resulting in 72. This works because folding a finger effectively subtracts 1 from the ones place (making it 9) and adds 10 to the tens place (from the folded finger's value), representing a group of 9.
