Up | Japanese Things and Quantities  

    In this picture, I am representing quantities by using blocks.



    Note !
    A block itself is not a quantity.

    We read a form from a presense and, conversely, realize a form by using a presense.



    And the quantity is a kind of those forms.
    It is important to discriminate the form from the presense, so as to discriminate the quantity from the presense.
