1) Pick a no frm 1 to9



2) Multiply your number by 2


3) Add 5 to the number u created in step2


4)Multiply the no.u created in step3 by 50


5) IF u havent had ur b'day 


Add 1760 else Add 1761


6)Subtract the year u where born




Example:


1.2
2.2*2=4
3.4+5=9
4.9*50=450
5.450+1760=2210

Trick to make appear a number four times

Posted by Unknown on 2:11 AM in
This trick is going to make a number you choose appear six times (to get the best effect it helps if you have a calculator). Think of a number between 1 and 9. Now multiply it by 7, then by 3, next by 11, then by 37, and finally by 13.




Example:


Let if i choose a no.4 then


4*7=28


28*3=84


84*11=924


924*37=34188


34188*13=444444 :-) 





also try this using C programing and C++ programming for your leisure time practices :-)

Digital Roots by Casting "9"

Posted by Unknown on 1:50 AM in ,



What is Digital root? 


If we add up the digits of a number until there is only one number left we have found what is called the digital root. In other words, the sum of the digits of a number is called its digital root.


Example:

For 5674, 5 + 6 + 7 + 4 = 22 and 2 + 2 = 4

» 4 is the digital root of 5674

One use of digital roots is for divisibility tests (like 3 and 9). This method makes it easier to calculate the digital root.

Example:

Example: 

Find the digital root of 257520643

Posted Image
Steps:

1. 2 + 7 = 9, cross out 2 and 7.

2.4 + 3+2 = 9, cross out 4, 3 and 2.

3.There are no other groups of numbers adding up to 9.

4.Add up the remaining digits, 5 + 5 + 0 + 3 = 13.

5.13 is more than 9, so 1 + 3 = 4.

6.The digital root is 4.

If there is nothing left after having cast out nines then the digital root is 9.
