We want to get to 51 using only the numbers 5, 6, 7 and 8.

First, let's write remember that:

8 = 2^3

6 = 3*2

Then we can start with:

8*6 = 48

This is close to the number we want, we are 3 units below.

And 8 - 7 = 1

       7 - 5 = 2

Then we can do:

8*6 + (8 - 7) + (7 - 5) = 51.

the answer is 9 because the question is telling how much it be together.
