Does the multiplication by 11 trick work for numbers that aren't two digits?

Does the multiplication by 11 trick work for numbers that aren't two digits? (eg. 123 * 11  where do I write 6?)

Yes.
123x11=1353Explanation: The answer begins with 1 and ends with 3. Since 1+2 = 3 and 2+3 =5, you take out the 2 and "insert" the 3 and 5 to get 1353. Hope this made sense

@starwraith Thanks!
