Two-Color Counter Model
To visualize integer arithmetic without relying on rote memorization, the two-color counter model uses physical or drawn tokens to represent positive and negative values. Commonly, a blue counter signifies a positive integer, while a red counter denotes a negative integer. Grouping and pairing these colored counters makes the processes of adding and subtracting integers highly intuitive.

In a corporate inventory system, integers are used to record the number of units added to or removed from stock. Which of the following sets consists entirely of integers?
In a professional inventory management system, a value that represents a whole quantity without any decimal or fractional parts—such as -12 for items removed or 25 for items added—is classified as a(n) ____.
Defining Integers in Financial Auditing
In professional environments, data is often categorized into specific mathematical sets. Match each term related to the set of integers with the description that best defines its role and characteristics.
In a professional inventory system, a value of -10 representing a stock shortage is not considered an integer because integers are restricted to positive numbers and zero.

In a logistics center, a warehouse supervisor uses a 'two-color counter model' on a visual board to help the team track daily inventory variances. Different colored magnets represent units that are either in surplus or on backorder. Match each component of this visual model with its standard mathematical representation or defined purpose.
An office manager uses a visual dashboard with blue and red counters to track the daily surplus or deficit in the departmental supplies budget. Following the standard conventions of the two-color counter model, what mathematical value is represented by a single red counter?
A manufacturing supervisor uses the two-color counter model on a dashboard to track quality control metrics. If red counters are used to represent defective parts (negative values), then ____ counters are used to represent parts that pass inspection (positive values).

In a workplace performance dashboard using the two-color counter model, a supervisor needs to determine the net balance of 'Performance Credits' (positive values) and 'Deductions' (negative values). Arrange the following steps in the correct order to model this calculation.
