## Step 1: Ascribe values

- 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.

Step 4

*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: 56Answer: 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)

It is best technique but suppose I want to multiply 7 x 5 how to do it using this technique

With this technique you can only multiply the numbers from 6 to 10, 6, 7, 8, 9 or 10 times as the values you ascribe to the fingers go from 6 to 10. You can always multiply 7x6 and subtract 7.

7 x 6 - 7 = 7 x (6-1) = 7 x 5

Thanks so much for posting this. At 49 I still have moments where I struggle with them and this will help a lot.

Thank you very much for sharing and teaching this old dog a new trick! ;) I knew of a trick with 9's that I learned on TV years ago after I learned the hard way, but I never knew this trick with the lower #'s. I am so happy, because I will be able to teach my 5 year old grand-daughter! :) I LOVE spending time with her we have so much fun learning we make games out of everything and this seems like a lot of fun too, so she'll enjoy learning. It's so much fun when you can pass on a easy way of learning something. I remember when I taught my youngest daughter the 9 trick, her eyes got so big and surprised like, WOW! lol Thank you once again. :)

If you write in one row the numbers from 8 to 0 repeating the number 4, and in a second row the pair numbers beginning with 0 you get it:

Row 1: 8 7 6 5 4 4 3 2 1 0

Row 2: 0 2 4 6 8 0 2 4 6 8

10 9 8 7 6 5 4 3 2 1

Another "trick" is this. If you know how to multiply 2 times any quantity:

8 x 4 = 8 x 2 x 2 = 16 x 2 = 32

As I say in the first step

" I heard this trick on the radio".I made the step by step pictures and explanations. When I entered the contest the Instructables staff should have seen that. I guess that if they had thought this instructable didn't follow the rules they wouldn't have accepted it.My apologies, I did not want to dishonour you and I'm sorry if I did!

You have my vote :)

Thanks for the vote :D

this...oh how wonderful....i would definitely vote for you on the hands down educational contest! 5 stars!

I must confess I prefer (my children) to learn them by heart, so that it finish to be assimilated as something that I've always known...

When one studies knowledge management a little bit, one meets the

competency matrix.Applied to

multiplying tablesit can be seen this way :unconscious incompetence;conscious incompetence;conscious competence;unconscious competence;avoid learning them by heart(with such aworkaround),I fear it takes far more time and efforts before it becomes anunconscious competence.I think what matters more is to find a way to make pupils learn them while playing instead of teaching pupils a way not to learn them."that was too much for that age"There are already so many things to learn before being

really in needfor multiplication tables...
