Formula:
To multiply 9 by a number (let's call it N, where N is 1 to 10):
1. Hold both hands out in front of you, palms facing you.
2. Count from left to right to the finger representing N (e.g., if N=3, it's the 3rd finger from the left).
3. Fold down that finger.
4. The number of fingers to the left of the folded finger represents the tens digit.
5. The number of fingers to the right of the folded finger represents the units digit.
Example: To calculate 9 x 3
Fold the 3rd finger from the left. There are 2 fingers to its left (tens=2). There are 7 fingers to its right (units=7). Result: 27.
