Hey you Blogger How are . . .
I hope you are fine and God always Blessing you . .
Check this out my new posting in June 2011 "Multiplication for fun".
Interesting products for various multiplication problems. Not very useful, but certainly curious. Don't think twice guys . . .here were . .go

The First Multiplication Trick For Fun

3 x 37 = 111 and 1 + 1 + 1 = 3 

 6 x 37 = 222 and 2 + 2 + 2 = 6 

 9 x 37 = 333 and 3 + 3 + 3 = 9 

 12 x 37 = 444 and 4 + 4 + 4 = 12

 15 x 37 = 555 and 5 + 5 + 5 = 15 

 18 x 37 = 666 and 6 + 6 + 6 = 18

 21 x 37 = 777 and 7 + 7 + 7 = 21 

24 x 37 = 888 and 8 + 8 + 8 = 24

 27 x 37 = 999 and 9 + 9 + 9 = 27

The Second Multiplication Trick For Fun

1 x 1 = 1  

11 x 11 = 121 

 111 x 111 = 12321  

1111 x 1111 = 1234321 

 11111 x 11111 = 123454321  

111111 x 111111 = 12345654321 

 1111111 x 1111111 = 1234567654321  

11111111 x 11111111 = 123456787654321  

111111111 x 111111111=12345678987654321 

What do you think .. .? :D.. . Memories it . . .:D

To multiply any for free

How are you blogger ? :D
I hope you have  a great day  . .
Enjoy my posting about  multiplication

To multiply any two like numbers with fractions that sum to 1 (for instance, 4 3/4 x 4 1/4), multiply the whole number by the next highest number (4 x 5) and append the product of the fractions (3/4 x 1/4). In the case of 4 3/4 x 4 1/4, 4 x 5 = 20. Then append the product of 3/4 x 1/4, 3/16. Thus, 20 3/16.


To multiply any two numbers whose ones digits sum to 10 and with like remaining numbers (for instance, 106 x 104) multiply the upper tens numbers by the next higher number (in this case, 10 x 11) and multiply the ones digits that sum to 10 (6 x 4) and then set the products next to one another successively (11024). Another example is 57 x 53. 5 x 6 = 30; 7 x 3 = 21; answer is 3021.


To multiply any number by any number of 9's (for instance, 28 x 99), append as many 0's to the multiplicand as there 9's in the multiplier (2800), and from this number subtract the multiplicand (2800 - 28 = 2772). The remainder is the answer. (2772)


Cross multiplication is a method of multiplying large numbers in a single line. Take the example 18 x 76. First multiply 8 x 6, set down the 8, and carry the 4. Next multiply 1 x 6, 7 x add the products and add the carried 4 to give 66. Set down the 6, multiply 1 x 7, and add 6 to the product to give 13 which you set down to conclude the problem and yield the answer, 1368. (To learn this, work a few examples on paper.)

Multiplication Trick For Free

In this post i would share about multiplication Trick,
 I know I know  . .Do you hate math, don't ?
me too guys . Sometimes I'm very like math. .:D but Sometimes I'm hate math . ..hahahaha..
Math is easy and fun if we know the trick of it but in here I explain about multiplication  . ..
This my first post about Multiplication Trick For Free . .
I have one book about math trick and tips :D Here we go. . .. .

First Trick :D
To multiply any number of two figures by 11

Write the sum of the figures between them.
Example 26 x 11 = 286.
(2 + 6 = 8; place the eight  between the 2 and 6)
When the sum is of the figures is more than 9, increase the left-hand number by the 1 to carry. ,
Example
87 x 11 = 968
(8 + 7=15); add 1 to 8 to get 9; place the five between the 9 and 8)
56x11 = 616
( 5+6 =11 ): add 1 to 5 to get 6, place the one between the 6  and 5 )
To multiply  any number of more than three figures by 11 find me on next posting ..okay .. ..:D

Second Tricks
To square any number of 9s
9s immediately without multiplying set down as many 9s less one (beginning at the left) as there are 9s in the given number, an 8, as many 0s as you do 9s, and a 1.
Example:
 999 x 999: put down 2 9s: 99. Then an 8: 998. then 2 0s (because you have 2 9s): 99800. The append a 1: 998001. That's it!

Third Tricks
To square any number ending in 5 :
Omit the 5, and multiply the number as it will then stand, by the next higher number, and append 25 to the product.
Example:
75 x 75.
Omit the 5:7 .
Next multiply 7 by the next higher number is 8 ;
7 x 8 = 56. Finally, append 25:
5625  That's the answer: 5625.
45x45. . . . .
Omit 5:4
Next multiply 4 by the next higher number is 5;
4 x 5 = 20 append 25
That's answer 2025

Multiplication

Fourth Tricks
To square any compound fraction containing 1/2, 
Like 5 1/2 for instance, Multiply the whole number by the next higher whole number and append 1/4 to the product.
Example
 5 1/2 x 5 1/2 = 30 1/4. (5 x (5+1) = 30; tag on 1/4 to get 30 1/4.).
