    I'm also an avid collector and recently was considering stopping, but this is quite inspiring.

    It might be worth noting that the card in the lower left is not correct. You can't divide 3 (or anything else for that matter) into 0. Kinda makes it even more interesting.

    This is a great blog -- I love both the layout of the photos and their content.

    As a math teacher, though, I feel compelled to respond to Josh's comment. Of course you can divide nonzero numbers into zero! What you can't do is divide by zero.

    0/3 is like saying a cake is divided into three pieces and you have none of them.

    That problem says 3/0, not 0/3. It is absolutely incorrect.

    Anonymous above, you are "absolutely incorrect" about division by zero in the image above, see:
    http://en.wikipedia.org/wiki/Long_division

    The flashcard correctly states 0/3=0...

    I found a set that my wife had purchased (from EduPress) that had the error you mention...even stated that 0/0=0!!!!

    An interesting discussion is worth comment. I think that you should write more on this topic, it might not be a taboo subject but generally people are not enough to speak on such topics. To the next. Cheers
