    >>> from matrix import Matrix

    >>> a = Matrix([[1, 2, 3], [4, 5, 6]])

    >>> b = Matrix([[10, 11], [20, 21], [30, 31]])

    >>> c = Matrix([[-23, 3, 8], [-13, 17, -21]])

    >>> d = Matrix([[32, 17], [-3, 11]])

    >>> e = Matrix([[9, 8, 7], [6, 5, 4]])

    >>> a.dim()

    (2, 3)

    >>> b.dim()

    (3, 2)

    >>> c.dim()

    (2, 3)

    >>> d.dim()

    (2, 2)

    >>> e.dim()

    (2, 3)

    >>> a + c
