>>13920717well, a square is 4, right? 4 corners and all that?
two squares is 8, now just add them up, and you get 16.
another way to get the same result,
you need to look for square numbers. square numbers can't be round because squares aren't round, they have edges.
numbers with sharp edges are 1, 4 ans 7. now, you can't construct a square shape with a 4, but you can with a 1 and a 7. you take two 1s, that's your square one, take two 7s, that's your square two. add it all together, and you get 16.
i love maths.
