Adding $-2 + (-4)$, $-2 + 4$, and $2 + (-4)$ with Counters

As an inventory clerk, you use a visual tagging system to reconcile daily stock. Red tags represent missing items (negative counters), and green tags represent surplus items (positive counters). Recall the two-color counter method to determine the net inventory value. Match each shift's tag grouping with its resulting net mathematical value.

A retail supervisor uses a visual tracking board where green magnets represent a profit of ${}1$ and red magnets represent a loss of ${}1$. To determine the total value of a ${}1$ profit combined with a ${}5$ loss (expressed as ${}1 + (-5)$) using the counter strategy, arrange the following steps in the correct procedural order.

A warehouse manager uses red stickers to mark items removed from stock ($-1$) and green stickers to mark items added ($+1$). When determining the net change for an order with one removal and five additions (represented as $-1 + 5$), the manager uses the counter strategy to cancel the single red sticker with one green sticker. What is the resulting net change?

In a professional accounting simulation, red counters represent debits (negative values) and green counters represent credits (positive values). True or False: To find the sum of $-1 + (-4)$ using the two-color counter strategy, you should group the one negative counter with the four negative counters to arrive at a total of five negative counters, yielding a sum of $-5$.

Inventory Reconciliation Using the Counter Strategy

A retail associate uses a digital ledger where green indicators represent register overages and red indicators represent register shortages. At the end of the day, the associate reconciles a consecutive shortage of 1 dollar and 4 dollars, modeled by the expression $-1 + (-4)$. Using the two-color counter strategy, the associate groups the single red indicator with the four red indicators. This action results in a total of ____ red indicators, representing a net shortage of 5 dollars.
