Subtracting and with Counters
The take-away model of subtraction is applicable when the signs of the two numbers are identical, as no neutral pairs need to be introduced. - For , start with positive counters. Taking away positive counters leaves positive counters, showing that . - For , start with negative counters. Taking away negative counters leaves negative counters, showing that . These examples provide additional reinforcement that removing counters of the same color from a larger collection straightforwardly aligns with the standard arithmetic rules for numbers with identical signs.

An inventory manager uses red chips to represent stock deficits. To solve the problem -7 - (-3) using the 'take-away' model, the manager starts by placing 7 red chips on a desk. According to this specific model, what is the next step to determine the final balance?
A logistics coordinator uses the 'take-away' model to manage freezer inventory. To represent a temperature adjustment of 'subtracting -5 from -12', they start with 12 red counters. According to this specific model, what is the next step and the final result?
A warehouse manager uses red counters to represent backordered items (deficits). To process a cancellation of 4 backordered items from an initial batch of 10 backordered items, the manager uses the expression -10 - (-4). Arrange the steps of the 'take-away' model in the correct order to find the new total of backordered items.
A billing clerk uses the 'take-away' model to visualize account adjustments. To solve the expression -15 - (-6), the clerk starts with 15 red counters (representing the initial deficit) and then removes 6 of those red counters.
A Laboratory Technician uses the 'take-away' model to visualize temperature adjustments relative to a baseline. In this model, blue counters represent positive deviations and red counters represent negative deviations. Match each subtraction expression to the correct initial setup and action used to find the result.
