distributive property is a(b+c)=ab+ac
it could be
8 is 'a' or
71 is 'a'
I prefer 71=a so
basically b+c=8
probably prefer positive so
some possible combls are
0 and 8
1 and 7
2 and 6
3 and 5
4 and 4
and the rest is just reverse
71(0+8)=71(0)+71(8)=0+568=568
71(1+7)=71(1)+71(7)=71+497=568
71(2+6)=71(2)+71(6)=142+426=568
71(3+5)=71(3)+71(5)=213+355=568
71(4+4)=71(4)+71(4)=284+284=568
