Cold-Chain Temperature Deviation Adjustments

An intern in the logistics department needs to explain the simplified values and determine which container requires a positive temperature adjustment. To assist the intern, recall and describe the exact mathematical rules used to evaluate and compare these adjustments:

  1. State the rule for evaluating double negatives, evaluate −(−15)-(-15), and provide the final simplified value.
  2. State the rule for evaluating absolute values with an external negation, evaluate −∣−15∣-|-15|, and provide the final simplified value.
  3. Recall how to compare positive and negative numbers, and state the comparison relationship between the two simplified values using the appropriate inequality symbol.
