Finger Multiplication of Ninth (9th) Time Table


Math Trick to easily multiply and learn the ninth (9th) time table. It is used to teach children to learn tricks about multiplication table.
Place your fingers as in the below image and number the fingers from 1 to 10. 
Example 
Consider the multiplication of 4 × 9. 

Step 1: 
Here 4 is to be multiplied by 9. 
So, fold the 4th finger and count the ones before the folded finger. 
Number of fingers before the folded finger = 3 fingers 
Multiply the number by 10, = 3 × 10 = 30 -----> (1) 
(as shown in the below figure)


Step 2: 
Count the fingers after the folded finger = 6 -----> (2) 
(as shown in the below figure)

Step 3: 
Add (1) and (2), 
= 30 + 6 = 36 
Therefore the solution to our problem 4 × 9 = 36 is easily found using the above trick. 

Note: 
If there is no finger below/above the considered (folded) finger, then consider the value as zero (0). 
Play the same for the below multiplications
1 × 9 = ?
2 × 9 = ?
3 × 9 = ?
4 × 9 = ?
5 × 9 = ?
6 × 9 = ?
7 × 9 = ?
8 × 9 = ?
9 × 9 = ?
10 × 9 = ?
