Not that I have time for this! ;-) but.. One possible answer would be

10 - (#1 + #4) = 5
10 - (#2 + #2) = 6
10 - (#3 + #6) = 1
10 - (#4 + #4) = 2

Ie fn(10 - (a + b))

Hi all,

The following has been bothering me. It was a problem that was supposed
to be a brain teaser for year 7 (12 year old) students.

Can anyone work it out?

If :
    1  (#)  4   =   5
    2  (#)  2   =   6
    3  (#)  6   =   1
then,
    4  (#)  4   =   ?

Cheers,

Dave
