Mereological Emptiness for the Signed Number Problem

It is well-known (at least in the education research literature) that primary school students face considerable difficulties in the understanding of negative integers (and numbers), related operations and their visualizations. In the present research, a proposal based on mereological principles is advanced towards solving aspects of the problem by the present author. Her proposal builds on the actual semantic content of what is taught expressed in algebraic terms, and natural types that can potentially be an explicit habit.
