Description: The trick to learn the nine times table is in your hands

Multiplication can be hard to learn with endless numbers to memorise.  Certain times tables are harder than others.  Sure nearly everyone knows their 2, 5 or 10 times tables but hands up who can do nine?

What if I were to tell you the answer to learning your nine times table is literally in your hands (fingers and thumbs too)?

I grew up with a learning difficulty called Dyslexia which made learning multiplication tough.  I muddled through hoping I wouldn’t get picked to answer a question in class and as a consequence I gave up learning maths.  Now as an adult I have an interest in the subject and enjoy learning of the patterns, symmetry and meaning mathematics brings to my world.

There is a trick to learning the nine times table which by a lucky coincidence requires having 10 fingers.  Or for the pedantic eight fingers and two thumbs.

## How to Learn Your Nine Times Table

Materials

• You will require 10 digits.  If you don’t have a complete set borrow someone else’s or alternatively fake hands can be purchased at any good joke store or online retailer.
• Optional- A Sharpie or Marker to write the numbers 1 to 10 on your knuckles.  Some may be inclined to make this permanent by visiting a tattooist.

Step One Spread your hands out with their backs facing you and thumbs and number them 1 to 10 to signify which number is to be the multiplier.  Whichever number is to be multiplied will need bending down.  We will only be using two digit numbers so numbers so tens are two the left of the bended digit and ones are two the left.

Now let’s begin.

One times Nine (1 x 9 = 9) Bend your first finger down, there are no fingers to the left of the one bended telling us this is a one digit number and nine fingers to the right (the ones).

Two times Nine (2 x 9 = 18) Bend your second finger down, there is one finger to the left of the one bended telling us this that the tens are two and eight fingers to the right (the ones).

Three times Nine (3 x 9 = 27) Bend your third finger down, there is two fingers to the left of the one bended telling us this that the tens are two and seven fingers to the right (the ones).

Four times Nine (4 x 9 = 36) Bend your fourth finger down, there are three fingers to the left of the one bended telling us this that the tens are three and six fingers to the right (the ones).

Five times Nine (5 x 9 = 45) Bend your fifth finger down (thumb), there are four fingers to the left of the one bended telling us this that the tens are four and five fingers to the right (the ones).

Six times Nine (6 x 9 = 54) Bend your sixth finger down (thumb), there are five fingers to the left of the one bended telling us this that the tens are five and four fingers to the right (the ones).

Seven times Nine (7 x 9 = 63) Bend your seventh finger down, there are six fingers to the left of the one bended telling us this that the tens are six and three fingers to the right (the ones).

Eight times Nine (8 x 9 = 72) Bend your eighth finger down, there are seven fingers to the left of the one bended telling us this that the tens are seven and two fingers to the right (the ones).
