You pretend to "infer", from a one-sentence description of how the Montessori method uses concrete materials to teach the basic arithmetic operations, that somehow other mathematical principles are absent from the Montessori pedagogy.
Of course these principles are demonstrated and taught in Montessori schools, also with concrete learning materials.
