## What is the Multiplication-by-11 Technique?

The multiplication-by-11 technique is a unique method designed to simplify and expedite the process of multiplying numbers by 11. Rooted in the patterns and structures of mathematics, this technique offers a quick and intuitive approach.

When multiplying a number by 11, the trick is often to add adjacent digits and place them in between. This rule is particularly evident with two-digit numbers. For instance, when multiplying 23 by 11, you'd get 253: the outer numbers remain the same, while the middle number is a result of 2+3.

Example: 23 x 11 = 2(2+3)3 = 253
