Order of Operations Training Guide

Imagine you are a department lead training a new junior analyst at a logistics company. The analyst needs to reconcile an inventory discrepancy using the mathematical expression −32÷4+(−2)(−7){}-32 \div 4 + (-2)(-7). To ensure they understand the foundational rules of calculations before they automate them in a spreadsheet, you ask them to write a clear explanation of how to simplify this expression.

In your role as the trainer, write a short response that covers the following:

  1. State the standard order of operations rules that dictate which calculation (division, multiplication, or addition) must be performed first, second, and last in the expression −32÷4+(−2)(−7){}-32 \div 4 + (-2)(-7).
  2. Recall and state the sign rules for dividing a negative number by a positive number (such as −32÷4{}-32 \div 4) and for multiplying two negative numbers (such as (−2)(−7){}(-2)(-7)).
  3. Provide the step-by-step simplification of the expression, clearly showing the intermediate values and the final result of 6.
