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

 At the age of 8 I had to learn the multiplying tables. I've never been good at memorizing lists or tables. It was easy to learn the tables from 1 to 5 but from 6 to 9 it seemed to be way more complicated... A year later I heard this trick on the radio and it saved my life. Since then I've taught it to many other kids. I passed such a bad time at school as I was the only one in my class who didn't know the tables so I hope this trick was useful for any parent or teacher who knew any child in this situation

SPREAD THE KNOWLEDGE!

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)

Step 3: Another trick for the table of 9




Here's an extra trick for the whole table of nine.

- First put your hands in front of you
- Then ascribe values from 1 to 10 to your fingers
- Fold the finger whose value you want to multiply nine times
- The fingers remaining unfolded in the left will be the tens
- The fingers remaining unfolded in the right will be the units


Example:  9 x 4

- Fold the fourth finger
- Fingers remaining unfold in the left  ->  3  (tens)
- Fingers remaining unfold in the right  ->  6 (units)
- Final result  ->  36
