Adding $-1 + (-4)$, $-1 + 5$, and $1 + (-5)$ with Counters

A warehouse supervisor uses a counter model to reconcile inventory adjustments, where red counters represent stock shortages and blue counters represent stock surpluses. To calculate the net result of a 5-unit shortage and a 3-unit surplus (mathematically represented as ${}-5 + 3$), the supervisor pairs the counters and removes the neutral pairs. Which of the following correctly describes what remains on the supervisor's desk?

A store manager is using the counter model to reconcile a ledger, where blue counters represent daily profits and red counters represent daily losses. Arrange the following steps in the correct order to evaluate the net result of a 5-unit profit followed by a 3-unit loss using the expression ${}5 + (-3)$.

In a corporate accounting department, a trainee uses the counter model to visualize balance adjustments. Red counters represent debits (negative values) and blue counters represent credits (positive values). Match each mathematical expression or term with its corresponding process and result in the counter model.

In a corporate accounting simulation, an analyst uses the counter model to evaluate the expression ${}-5 + 3$, where red counters represent negative values (debits) and blue counters represent positive values (credits). True or False: After forming and removing 3 neutral pairs, the analyst is left with 2 red counters, resulting in a final sum of -2.

During a corporate training session on visual ledger reconciliation, a financial instructor demonstrates adding $-5 + 3$ and ${}5 + (-3)$ using red counters for negative values (debits) and blue counters for positive values (credits). The instructor emphasizes a key rule from this model: after removing all neutral pairs, the final sum always carries the sign of the group that had ________ counters initially.
