Documenting Ledger Entry Rules

As part of your training as an inventory reconciliation clerk, you are drafting a quick-reference handbook for new hires. The handbook needs to explain two mathematical notations used in ledger adjustment reports: −(−9)-(-9) (the opposite of a negative adjustment) and ∣−9∣|-9| (the absolute magnitude of the adjustment).

Write a brief explanation for the handbook that addresses the following:

  1. Recall and state the mathematical definition of the double negative notation in −(−9)-(-9).
  2. Recall and state the geometric definition of the absolute value notation in ∣−9∣|-9|.
  3. Show how both expressions are evaluated step-by-step.
  4. State the final relationship between −(−9)-(-9) and ∣−9∣|-9| using an equality or inequality statement.
