hiii...ma frndz...here m wid ma 1st article... 

these r sum interisting information abt 'numbers'...jst watch out...

• d greatest no. one can make by 3 digit is 9^{9^9} !! it can b shown dat dis no. has abt 369693100 digits.assuming there can b 50 digits per line,nd 40 lines per page,in order to write d no.one will need at least 184 vol.of books each of 1000pages ,forthmore yet another vol. of abt 847 pages!!


• Perfect no.:  a no. is called perfect if it equals d sum of all its divisor(xcept d no. itself).d 1       st four perfect nos. r 6,28,496,8128.nd they r known to be Euclid..but most interesting is dat it took 17 century after euclidbefore d fifth one was discovered..which happehs 2 b 33550336..till date we know 38 of these nos.nd amazingly dey r all even no. ONE OF D OLDEST UNSOLVED PROBLEM IN MATH IS'DOES THERE NE ODD PERFECT NO.???'


• magic of number??-now frndz lets paly.. take a 3 digit no.such dat its ist nd last digits r different.reverse them nd substract the smaller one frm d other reverse d result and add it to d result. interestingly u'll always get 1089.(may not valid for 100,102..).

  now check dat- 

  
   12-1=,          

              3*(2+4)=

         95/5=9+5+5

         3+3+3+1+1=33/3+1-1....if u knw more like dis plz tell me(nudge me).

• d following two nos.r equals to thesum of the factorial of their respective digits-

                                 145=1!+4!+5!,  40585=4!+0!+5!+8!+5!......do u know more???

• 7*9=63

       77*99=7623 

       777*999=776223

       7777*9999=77762223....

• 123456789*9=111111111

                          *18=222222222

                                            *27=333333333

                          *36=444444444   ...well..compute d rest

      i've collected them frm various sources....

    do rate me if u like it....comment even if u dont like it..

     njoy.......cheers.....
