Math Buddy is the world’s most popular subscription-based Math learning site Mathbuddy provided some  Trick to easily Math Trick using Finger Multiplication of 6 To10 Time Tables.  It is used to teach children to learn tricks about multiplication time tables.

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).
