A technician is monitoring a cooling system where the temperature deviation is -7 degrees. They need to subtract a negative adjustment of -4 degrees. The calculation is -7 - (-4). According to the rule of adding the opposite, which expression is equivalent to -7 - (-4)?

A project manager is adjusting a resource log. To simplify the calculation of subtracting a negative variance of 15 hours from a scheduled 9 hours, written as 9 - (-15), the manager applies the rule of 'adding the opposite' and rewrites the expression as 9 + ____.

A logistics coordinator is reconciling inventory records. When an 'item return' (modeled as a negative adjustment) is removed from a ledger, the coordinator uses the rule of 'adding the opposite' to simplify the entry. Match each original subtraction record with its equivalent simplified addition expression.
