This works for even numbers only.
6x2 = 12
6x4 = 24
6x6 = 36
6x8 = 48
The number you are multiplying by is always the number in the units column. 6x2 = 12
The tens column is always half the number in the units column.

Multiplying by 8 can be achieved by doubling three times:
Example:
Q. What is 742 x 8?
A. 742 x 2 = 1484
.....1484 x 2 = 2968
.....2968 x 2 = 5936
The answer is 5936

Hold both hands up in front of you with your palms facing you.
Whatever you're multiplying by (say 8) bend down that finger.
(The 8th from left to right)
The fingers to the left of the bent finger are the tens (7) and to the right the units (2).
The answer ot 8 x 9 is there for 72.

11 x 9 is easy
12 times nine is just a little mnemonic.
12 is 10 + 2
remember the 2
2x9 = 18
just stick a 0 in the middle

Here is another trick
Whatever you re multiplying by 9, the tens of the answer is always one less.
eg. 8x = 70 something 4x = 30 something and so on
The digits in the answers of the 9 times table always add up to 9.
(The tens and units ALWAYS ad up to 9 !)
eg. 7 x 9 = 60 something
6 + ? = 9
so 7x 9 =63
Another method of multiplying by 9
Multiplying by 9 is really multiplying by 10 and taking away you are multiplying.
So, 8×9 is just 8×108 which is 808 or 72.
Let’s try a harder example: 46×9 = 46×1046 = 46046 = 414.
One more example: 68×9 = 68068 = 612.
Multiplying by 99, or 999 is similar
To multiply by 99, you multiply by 100 and taking away you are multiplying.
So, 46×99 = 46x 100  46 = 460046 = 4,554
To multiplying by 999, you multiply by 1000 and taking away you are multiplying.
38×999 = 38x100038 = 3800038 = 37,962

The eleven times table has always been very easy to learn up to 9 x 11.
Here's a way of multiplying large numbers by 11 too:
To multiply any number of two figures by 11:
Example:
Q. What is 34 x 11 ?
A. Add the first and second digits ... 3 + 4 = 7;
....Place the answer between the the first and second digits ..... 374
The answer is 374.
NB. When the sum is of the first and second digits is more than 9, increase the lefthand number by the 1 to carry.
Example:
Q. What is 98 x 11 ?
A. Add the first and second digits ... 9 + 8=17
....Add 1 to 9 to get 10
....Place the 7 between the 10 and 8
The answer is 1,078
To multiply any number of three figures by 11:
You add pairs of numbers next to each other, except for the numbers on the edges.
Example:
Q. What is 324 x 11 ?
A. Write down the first digit ... 3
.......Add the first and second digits ... 3 + 2 = 5
.......Add the second and third digits .. 2 + 4 = 6
.......Write down the last digit ........... 4
The answer is 3564.
Does it work for all three digit numbers?
To multiply any number of four figures by 11:
Q. What is 3254×11 ?
A. Write down the first digit ... 3
.......Add the first and second digits ... 3 + 2 = 5
.......Add the second and third digits .. 2 + 5 = 7
.......Add the third and fourth digits .. 5 + 4 = 9
.......Write down the last digit ........... 4
The answer is 35794.
Remember when the sum is of the first and second digits is more than 9, increase the lefthand number by the 1 to carry.
An example involving carrying:
Q. What is 4657 × 11 ?
A. Write down the first digit ... 4
.......Add the first and second digits ... 4 + 6 = 10
.......Add the second and third digits .. 6 + 5 = 11
.......Add the third and fourth digits .. 5 + 7 = 12
.......Write down the last digit ........... 7
Going from right to left write down 7
Notice that 5 + 7 = 12
Write down 2 and carry the 1
6 + 5 = 11, plus the 1 you carried = 12
So, write down the 2 and carry the 1
4 + 6 = 10, plus the 1 you carried = 11
So, write down the 1 and carry the 1
To the left most digit, 4, add the 1 you carried
So, 4657 × 11 = 51,227

When you’re multiplying two numbers together and one of the numbers is even, you can divide that number by two and multiply the other number by 2. You can do this over and over until you get to multiplication this is easy for you to do.
Q. What is 14 x 16?
A. Double one number and halve the other number
14×16 = 28×8
This is still to hard for me so double one number and halve the other number again
28×8 = 56×4
This is still to hard for me so double one number and halve the other number again
56×4 = 112×2
Now that is easier for me.
112×2 = 224
Here is another example:
Q. What is 12 × 15?
A. 12×15 = 6×30
6×30 s the same as 6×3 with a 0 at the end so the answer is 180.
