## Multiplication Tricks – Multiplying by 11

August 30th, 2009 by Steven Pomeroy | 4 Comments | Filed in Multiplication Tricks

One of the easiest **multiplication tricks** that I know of is also one of the most impressive. It is the multiplication of two-digit numbers, and, like many other **math tricks**, there is an easy rule that you can use to solve problems of this sort very quickly in your head.

An Example:

44 x 11

The technique for quickly solving multiplication problems involving any two-digit number by 11 is easy to remember. Simply add the two digits and insert the result in between the two digit number.

In our example:

44 x 11

4 + 4 = 8, so simply insert “8” between “4” and “4”:

484

So then we have quickly found that

44 x 11 = 484

Now wasn’t that easy?!
