You will end up eight distinct numbers $a,~b+8,~c+16,~d+24,~e+32,~f+40,~g+48,~h+56$.
Each of a,b,c,d,e,f,g,h is distinct and between 0 & 9.
So the sum $a+b+c+d+e+f+g+h=36$
What is $\sum\limits_{k = 1}^7 {8k} = ?$

(Clapping)(Clapping)(Clapping)(Clapping)(Clapping)

its 224 + the 36 makes it 260.

but could you explain again how you got those two observations?
