I covered the 1 to 10 times tables in the post How to Learn Your Times Tables Fast but it helps to also learn your 11 and 12 times tables. I’ve posted about the 12 Times Table.

The eleven times tables is one of the simplest. I’m sure that you already know it from 1 through 10:-

- 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

Bu what about 11 x 11 and 12 x 11?

You could just learn them:-

- 11 x 11 = 121
- 12 x 11 = 132

I think many people make mistakes with these final two, it could be because there are 3 digit numbers to remember (rather than the usual less intimidating one or two digit answers). So here’s an alternative approach, where you just break it down into easy steps:-

- 11 x 11 = (10 x 11) + (1 x 11) = 110 + 11 = 121
- 12 x 11 = (10 x 11) + (2 x 11) = 110 + 22 = 132

Just practice this in your head a few times and it will stick. Remember if you are asked “what is 11 x 11?” Just break it down:-

11 x 11 is the same as 10 x 11 plus 1 x 11 = 110 + 11 = 121

Using the same method:

12 x 11 is the same as 10 x 11 plus 2 x 11 = 120 + 22 = 132

If you repeat these just three or four times you will be able to do them in a split second.

I came up with these methods for the 11 and 12 times as a result of a comment left in my original “How to Learn Your Times Table Fast” post. Do you have better tricks for the eleven and twelve times tables? Do you think these techniques work, or is best to just learn through repetition? I think a mixture of learning tricks and repetition is best and that thinking about the techniques and the logic behind them helps to secure the tables in your memory. It would be great to hear your opinion.
