What's the point of the 11 times table?

As an immigrant to this great country as a 10 years old child many years ago, I was always curious as to why the primary schools in this country are required to teach children the 11 and 12 times table.

Surely you only need to memorise the 1 to 9 times table to do any multiplication or division in a base 10 numbering system.

Perhaps the 12 times table might be useful for converting feet to inches but I am struggling to think of a use for the 11 times table.

Does anyone have a good explaination for this?

Thanks for all the interesting responses.

I can't agree with not learning the 1 to 9 times table since it is fundamental to understanding how to multiple and divide any number (in base 10).

12 pence in a shilling is a good reason to know the 12 times table since you need to use money everyday. However, we don't have shillings anymore!

Also, there's 16 ounces to a pound but we don't ask primary school pupil to memorise the 16 times table!
