Counter Models in Financial Visualization
In a professional development workshop, a visual counter model is used to represent adding a positive integer (such as a profit) and a negative integer (such as a loss). Define what a 'neutral pair' is in this model and state the two properties of the resulting sum that the leftover counters represent.
