# 11 Times Table: How to Learn in 2 Minutes

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.
