Mind Mathematics: Trick Set #5

Is it us, or is it actually tough to remember the table of 9! When we were kids, it was difficult for us to remember the table of 9, therefore, here you will be learning another mind-blowing and useful trick to memorize the table of 9 by just using your fingers. You don’t even have to calculate anything in your head for this trick.

Multiplication By Fingers

Place both your hands directly in front of you with your fingers properly stretched. Now, if you want to multiply 9 by any other number, you just have to fold the finger of that number going from left to right.

For example, if you want to multiply 9 by three. Fold the third finger of your hand from left to right, i.e. the third finger of your left hand in this case. Now, calculate the sum of fingers on one side of your folded finger, which is 2, and the other side of your folded finger, up to the last finger of your right hand, which is 7. Therefore, 9 * 3 = 27, which is the correct answer. It might seem confusing on your first reading, but when you try it practically, it is fun to learn this trick.
