OpenStudy (phi):

1. think of a number but tell it . x 2. add the same number in it. x+ x=2x 3. add 40 in it 2x+40 4. divide the total by 2 (2x+40)/2 = x+20 5. subtract the remaining by the original number x+20-x= 20 6. the answer you'll get is 20 !!! yes

OpenStudy (anonymous):

Let n be the number. 1. n +n =2n 2. 2n + 40 3. (2n+40)/2 = n+20 4 n+20-n = 20 Not interesting :(

OpenStudy (anonymous):

@RolyPoly if u dont think its interesting then dont look at it ...

pick any number multiply with 0 you get 0

OpenStudy (ajprincess):

There is another 1 like this. Think of a two digit number. Find the sum of the digits. Subtract that from the original number. The answer u get will be a multiple of 9.

OpenStudy (anonymous):

ok lets mold the trick 1. think of a number but dont tell it . 2. add the same number in it. 3. add 30 in it 4. divide the total by 2 5. subtract the remaining by the original number 6. the answer you'll get is 15 !!!

OpenStudy (anonymous):
