So just because paper was invented before computers, it doesn't necessarily mean you get more to the basics of the subject by using paper instead of a computer to teach mathematics.
Piemēram, ja papīrs tika izgudrots pirms datora, tas uzreiz nenozīmē, ka jūs labāk varēsit apgūt pamatlietas, ja lietosit papīru, nevis datoru, lai mācītu matemātiku.
