Negative Numbers: Bridging Contexts and Symbols

At the latest PME-NA (35), a working group met on the topic of negative numbers.

We began a productive discussion on issues related to each of these categories and would like to broaden the discussion with the inclusion of members from the international community. Further we aim to develop research collaborations around mutual areas of interest
