Training on Division Involving Zero

You are a shift supervisor at a retail company training a new employee on how the store's inventory database handles calculations involving zero. The employee is confused by two scenarios on their weekly tracking report:

  1. A product category that had 0 sales over 4 days, represented by the expression 04\frac{0}{4}.
  2. A promotional item with 4 sales recorded over 0 days (due to a system logging delay), represented by the expression 40\frac{4}{0}.

Explain the difference between these two expressions to the employee. In your explanation, clearly state the mathematical result of each expression and describe why dividing a number by zero is undefined while dividing zero by a number results in zero.
