A friend told me a story from school:



The question is, "How much will it be if you add 8 tablespoons to 7 forks?" The child replied, “7 forks and 8 tablespoons.” The teacher, clear matter, noted the answer as wrong. In his narrow world, the answer should have been “15”.



This story arose as a result of the discussion of a single formula invented by bureaucrats to assess the efficiency in which the values of different dimensions were combined. He gave an example to show that even a child understands that this cannot be done.
