1. Put the palms of the hand facing you. You have ten fingers. Each finger represents a number. The one to the left, the big toe of the left hand, is number 1. The one on your right, the big toe of your right hand, is number 10. If you are asked how much is 9x1, you have to lower the first finger, number one, since you will multiply by one. You count how many fingers are left. In this case, none. And how many are left? Nine. That is the result.

2. Now let's calculate how much are 9x2. Which finger should you go down? The second! Now count the fingers left on your left: one. And to the right? Eight. The result, therefore, is 18.

3. In this way you can calculate the whole multiplication table. For example ... How much would 9x4 be? The number four finger is lowered. Count the fingers that are left ... and now the ones that are on the right. How much do you get? Clear! 36!

4. Another example: 9x7. In this case, the finger that makes the number seven is lowered. Now count the fingers left on your left ... six. And to the right? 3! The result, therefore, is 63. Have you seen how easy?

5. One last example: we calculate how much is 9x10. The number ten finger is the right thumb, right? On the left we have nine numbers left. On the right, zero. The result? 90!
