Roman Numbers.......!!

Indian Numbers........!!

Same 3 Digit Numbers....!!

Step1:
Think of any 3 digit number,
but each of the digits must be the same as. Ex: 333, 666.

Step2:
 Add up the digits.
Step3: 
Divide the 3 digit number with the digits added up.

" The number is always 37 "

<<<< Day of the Date >>>>

Remember this table which will help you to calculate :
January        0
February      3
March           3
April             6
May              1
June             4
July              6
August         2
September  5
October       0
November   3
December   5


lets start with my birthday..that is 16th july 1992.

Step1:  Ask for the Date. Ex:16th july 1992.
Step2:  Number of the month on the list, July is 6.
Step3:  Take the date of the month, that is 16
Step4
:  Take the last 2 digits of the year, that is 92.
Step5:  Find out the number of leap years. Divide the last 2 digits of the year by 4, 92 divide by 4 is 23.
Step6: Now add all the 4 numbers: 6 + 16 + 92 + 23 = 137.
Step7: Divide 137 by 7 = 19 remainder 4.


Monday        1
Tuesday       2
Wednesday 3
Thursday      4
Friday           5
Saturday      6
The reminder tells you the day.
Thursday 4
so the answer is Thursday.........!!!!

Fact of Number 11

suppose take a number between 10-100
then reverse the such as if you take a number 12
then make it as 21
add 11 to the obtained number 21+11=33
it is divisible by 11
for example take 45
then reverse it then it would become 54
add 11 to it then it is 66.....!!!

Sum Of Number Series

I have a new trick.
How we find sum of a number series like.
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = ?
So, First take next digit of last number that is 11.
and then take mid digit of series that is 5.
11 * 5 == 55
this is the also the sum of=
1 + 2 + 3 + 4 + 5+ 6 + 7 + 8 + 9 + 10 = 55.....!!
