Here is an opportunity to practice your math tricks skills by multiplying 2 digit numbers by 11. Remember – add the two digits in the number being multiplied by 11, then insert the sum in between the two digits.  Don’t forget to carry over if it is required.

These multiplication sheets are meant to be solved in your head.  One trick is to speak out loud as you solve the problems; this will help you to remember the partial answers better – especially when you have to carry numbers.  With just a little practice, you will soon be able to solve these types of problems very quickly.

Multiplication Tricks – Multiplying by 11

August 30th, 2009 by admin | 2 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?!

Multiplication Times Tables

In order to become very good at fast mental math tricks, you really need to memorize multiplication times tables.  Don’t panic!  All you need to concentrate on now is the basic multiplication table:

This may seem a little daunting, but it really is not.  I would suggest printing it out and refer to it when you have a free moment, like waiting in line at the grocery store, etc.  In no time at all, you will surprise yourself at how well you know it!

Once you have this table down pat, you may want to make up more complex multiplication times tables.  For instance, make up 10 x 10 tables for the numbers 11 – 20, 21 – 30, and so on.  The basic 1 – 10 table is really necessary for you to know, but the more complex times tables will give you an edge over other “math geniuses”!
