Finger Multiplication of 6,7,8,9,10 Time Tables
Here is a mathematical Trick to multiply easily the numbers from 6 to 10. It is used to teach children to learn tricks about multiplication tables.
Place your fingers as in the below image and consider the value of fingers in each hand to be 6, 7, 8, 9 and 10—in the order from small finger to thumb.
Example :
Consider the multiplication of 7 × 8.
Make the finger numbered 7 in the left hand to touch the finger numbered 8 in the right hand.
Step 1:
Now in the left hand, count the finger which is touching (7) and the ones below that = 2 fingers
Similarly in the right hand, count the finger which is touching (8) and the ones below that = 3 fingers
Add the above counted fingers = 2 + 3 = 5 fingers
Multiply the number by 10 = 5 × 10 = 50 —–> (1)
Step 2:
In the left hand, count the fingers above the touching finger = 3 fingers
Similarly in the right hand, count the fingers above the touching finger = 2 fingers
Multiply both = 3 × 2 = 6 —–> (2)
Step 3:
Add (1) and (2),
= 50 + 6 = 56
So, the answer for 7 × 8 = 56 which is easily found through the above trick.
Note:
If there is no finger above the considered (touched) finger, then consider the value as zero (0).
Play the same for the multiplications given below
6 × 6 = ? 6 × 7 = ? 6 × 8 = ? 6 × 9 = ? 6 × 10 = ?
7 × 6 = ? 7 × 7 = ? 7 × 8 = ? 7 × 9 = ? 7 × 10 = ?
8 × 6 = ? 8 × 7 = ? 8 × 8 = ? 8 × 9 = ? 8 × 10 = ?
9 × 6 = ? 9 × 7 = ? 9 × 8 = ? 9 × 9 = ? 9 × 10 = ?
10 × 6 = ? 10 × 7 = ? 10 × 8 = ? 10 × 9 = ? 10 × 10 = ?
Finger Multiplication of Nine Times Table
There is a mathematical trick to multiply easily and learn the 9 times table. It is used to teach children to learn tricks about multiplication tables.
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 multiplications given below.
1 × 9 = ?
2 × 9 = ?
3 × 9 = ?
4 × 9 = ?
5 × 9 = ?
6 × 9 = ?
7 × 9 = ?
8 × 9 = ?
9 × 9 = ?
10 × 9 = ?
