Subtracting $5 - 3$and$-5 - (-3)$ with Counters

Subtracting $7 - 5$and$-7 - (-5)$

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.

Subtracting $3 - 1$ and $-3 - (-1)$ with Counters

A logistics coordinator uses red counters to represent minutes of delivery delays. To model the expression $-14 - (-6)$ using the 'take-away' model, the coordinator starts with 14 red counters and removes ____ red counters.

Subtraction Property of Integers

A corporate trainer is using the 'take-away' model to help employees visualize budget changes. When subtracting integers that have the same sign (such as $-10 - (-3)$), what is the primary reason that neutral pairs are not required to find the answer according to this specific model?
