Standardizing Auditing Rules for Absolute Value and Opposites

An inventory clerk is reviewing automated ledger adjustments and discovers two different formatting styles used to represent a 16-unit balance reconciliation: −(−16)-(-16) and ∣−16∣|-16|. To ensure the database rules are documented correctly in the company standard operating procedures, write a short essay recalling and explaining the mathematical principles behind these two expressions.

In your essay, you must:

  1. State the standard algebraic rule for simplifying the opposite of a negative number (a double negative), apply it to −(−16)-(-16), and write its simplified value.
  2. State the definition of absolute value in terms of distance from zero, apply it to ∣−16∣|-16|, and write its simplified value.
  3. Compare the two simplified values and write a final equation representing their mathematical relationship using the correct comparison symbol.
