The document describes a method for multiplying any two-digit number by 11 quickly. The method involves separating the two digits of the number mentally, adding the digits, and placing the result in the middle with the original digits. For example, to multiply 11 x 54, separate 54 into 5 and 4, add them to get 9, and place the 9 in between to get 594. If adding the digits results in a number greater than 9, only the ones digit goes in the middle and the tens digit is carried over.
