As it's still close season and I have nothing to do (student life's great) I thought I would share something I found. How many squares can you see? please log in to view this image
It can't possibly be an even number if you look at it! they are all in multiples of two apart from the overall outside single! Ergo, it must be an odd number!
I didnt actually say it was MY answer. just that i'd seen it on fb. I can never get them things right anyway, so I don't normally bother
It can be an even number Dave, you can make nine 4x4 squares. Besides, I still get 40 no matter how I count them
