Adding Integers with Different Signs

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.

An inventory clerk uses the standard two-color counter model to visually track daily stock levels on a whiteboard. In this standard model, a blue counter is used to represent a negative integer, such as a stock deficit.
