Alternatively, since the wrong kind of " simplification" might be as disastrous as it was in the 1970s, the challenge of making arithmetic more common-sensible might require increasing its complexity. For example, injecting the addition and subtraction of *proper* combinations of American coins provides strong conceptual understanding of the commonly confusing notions of "carrying/borrowing." But that injection likely would be widely regarded as "complicating" the arithmetic.
