Answer:
you can use a median method of counting and eliminating each side being each cut but the difference would it would be an equal number as the central off number cut divides one piece of wood into an even number.
Another operation is subtracting the cuts from the pieces you have 7 - 6 = 1 whole. Meaning the answer is correct if you are left with 1
If the cuts were even then you would have an a number of pieces that amount to an odd number.
So with 7 they are even and positive.
With counter checking they are positive as you always start with one piece of wood.
