The only way I know to solve it is to substitue the numbers in to find the highest? I am not sure if I have found all of the combinations doing that or not. By doing only that I came up with 9 as my answer?\r

You can put this solution on YOUR website!
c • a b – d
\n" ); document.write( "Unless d=0 the equation=0
\n" ); document.write( "ab=a*b
\n" ); document.write( "You can write the equation: a*b*c-0=6
\n" ); document.write( "It doesn't make any difference what numbers the a, b & c represent the answer will be the same.
