Tables of 6, 7, 8 and 9 in your hands

Step 1: Ascribe values

 First put your hands in front of you as shown in the drawing
- In each hand, ascribe a value from 6 to 10 to each finger

Step 2: How to multiply

Step 1
Choose the numbers to multiply. Example: 7x8

Step 2

Put together the fingers whoses values you want to multiply.

Step 3

Now count the touching fingers and the ones below them. The number you get will be the tens. Example: 5

Step 4

Now multiply the fingers above the ones touching of the left hand and the ones in the right hand. The number you get will be the units. Example: 3x2=6

Answer: 56

**In some cases you will get a number of units bigger than nine, in that case sum both quantities**

Example: 7x6

- Touching fingers + the ones below  ->  3

- Fingers above the ones touching in left hand  ->  3
                                                                                                               3 x 4 = 12
- Fingers above the ones touching in the right hand  ->  4

                                                                                3        (tens)
Now we've got 3 tens and 12 units  ->                  + 12      (units)
                                                                                  42     (final result)
