A: A negative percentage indicates a decrease rather than an increase between the values.

Q2: Why can't the old value be zero?
A: Division by zero is mathematically undefined, making percentage change calculations impossible.

Q4: What's considered a "good" percentage increase?
A: This depends entirely on context - business metrics, test scores, or investment returns each have different benchmarks.

Q5: Can I calculate percentage decrease with this?
A: Yes, the result will be negative for decreases, but you can report it as a positive "decrease" if needed.
