5. Frequently Asked Questions (FAQ)

Q1: How do I calculate 15% off without a calculator?
A: Multiply the original price by 0.85, or calculate 10% (move decimal left once), add half of that (5%), then subtract from original.

Q2: Does this work for any currency?
A: Yes, the calculation is the same regardless of currency, though results will be in the same currency as your original price.

Q3: How is this different from adding 15% to a price?
A: Adding 15% would multiply by 1.15, while subtracting 15% multiplies by 0.85 - they are inverse operations.

Q4: Can I use this for multiple discounts?
A: No, this calculates a single 15% discount. Stacked discounts require sequential calculations.

Q5: What if I want a different percentage off?
A: Change the multiplier to (100 - discount%)/100. For 20% off, multiply by 0.80.
