Hard math puzzle, please help?

The puzzle says that you have to draw 15 circles like this:

( )( )( )( )( )

( )( )( )( ) You have to put the numbers 1-15 into it.

( )( )( ) You can’t use any number twice

( )( ) and you have to subtract the two numbers

( ) like this :

(15) – (14) – (2) – ( 8 ) – ( 3 )

( 1 ) – (12) – ( 6 ) – ( 5 )

15 – 14 = 1, the 1 goes directly below the two numbers.

(15) – (14) – (2) – ( 8 ) – ( 3 )

( 1 )

14 – 2 = 12 ,the 12 goes directly below the two numbers.

(15) – (14) – (2) – ( 8 ) – ( 3 )

( 1 ) – (12)

12 – 8 = 4, the 4 goes directly below the two numbers.

(15) – (14) – (2) – ( 8 ) – ( 3 )

( 1 ) – (12) – ( 6 )

8 – 3 = 5, the 5 goes directly below the two numbers.

(15) – (14) – (2) – ( 8 ) – ( 3 )

( 1 ) – (12) – ( 6 ) – ( 5 )

And so on and so fourth.

Please help,
