Hi, this is 2187 game, 1+2=3!

How to play:
The odd number should add itself to become a larger number, like 1+1 =2, 3+3 =6.
The even number should add half of itself to become a larger number, like 2+1=3, 6+3=9.
However, odd number can add nothing but itself and even number can not add itself to become larger number, such like 2 cannot add 2 to be 4，3 can just add 3 to be 6.

So, 1+1=2,2+1=3,3+3=6,6+3=9,9+9=18,18+9=27......1458+729=2187!

Get it now, add to 2187!
