interestin math qns

yay! my father downloaded 2012! he said its not illegal. *shrug * =='' k, nvm. there is one very interesting math qns. it may sound complicated but its actually really easy n fun. it jus require an easy-peasy addition & subtraction, thats all. can use a calculater if u want 2. i will use alphabets 2 represent the numbers (aka algebra). follow the steps:

1) think of a 3-digit number. but the numbers has to b different, not 111, 222... etc. (eg. ABC)

2) now make the number oppsite. (eg. ABC opposite CBA)

3) take the bigger number of the two subtract the smaller number (eg. CBA - ABC)

4) get the ans (eg. DEF)

5) make that number opposite again. (eg. DEF opposite FED)

6) add the two number together (eg. DEF + FED)

7) i bet yr number is 1089 right?

if your ans is not, try again. cos no matter what 3-digit number you think of, as long as they r not the same, n oso follow the steps given, your ans will always b 1089! don believe try other numbers!

let me give an example:

my number is 123, opposite will be 321

321-123=198

198 opposite will be 891

198+891=1089

now try other numbers. amazing isn't it?! :)
