The Eleven Times Tables
1 x 11 = 11
2 x 11 = 22
3 x 11 = 33
4 x 11 = 44
5 x 11 = 55
6 x 11 = 66
7 x 11 = 77
8 x 11 = 88
9 x 11 = 99
10 x 11 = 110
11 x 11 = 121
12 x 11 = 132
Note
There is a strong pattern in the 11x table. Can you spot it?
The Trickies...
Due to the strong pattern, most of the eleven times table is not difficult to learn.
Let's get 11 x 11 and 11 x 12 cracked as well...
think of it as making a number sandwich!

Did you know...?
There is a quick way to work out if a number is divisible by 11:
Add together alternate digits and then find the difference. If the difference between the two numbers is a multiple of 11, then the original number is a multiple of 11
Let's try it: is 2,728 divisible by 11?
1. Start with the first number
Add alternate digits 2,728
2 + 2 = 4
2. Start with the second number
Add alternate digits 2,728
7 + 8 = 15
The difference between 15 and 4 is 11.
This number IS divisible by 11 (in fact, 11 x 248 = 2,728)
Let's try again, with a smaller number.
Is 429 divisible by 11?
4 + 9 = 13
2 - this one is on its own.
Find the difference: 13- 2 = 11
429 IS divisible by 11 (11 x 39 = 429)
And a larger number...
Is 63,976 divisible by 11?
6 + 9 + 6 = 21
3 + 7 = 10
Find the difference: 21- 10 = 11
63,976 IS divisible by 11 (11 x 5,816 = 63,976)
