perplexus.info :: Numbers : Round the square

Round the square (Posted on 2004-07-30)

Can you place the numbers 1 to 8 on the outer squares of a 3x3 grid, so on every side the middle number is the sum of the corners next to it?

Can you manage to place the same numbers so the middle number of each side is the average of the corners next to it?
