WORKSPOTHQ — FICTIONAL TEACHING EXAMPLE A fictional fuel receipt: label before magnitude Synthetic guidance only. Not a real receipt, claim requirement, or measured processor output. Sale ₹4,000.00 Check: Purchase amount Volume 40.49 L Check: Quantity, not money Rate ₹98.79/L Check: Unit price Cumulative amount counter ₹36,473,023.61 Check: Pump history, not this purchase 40.49 × 98.79 = 4,000.0071. That supports a purchase near ₹4,000, but the displayed quantity and rate may be rounded. Preserve the printed sale amount rather than silently recalculating it. REVIEW CHECKLIST 1. Locate the sale amount and currency. 2. Check litres or gallons and the unit rate. 3. Ignore cumulative volume and amount counters as purchase totals. 4. Verify date, merchant and receipt number against the original. LIMITATIONS Displayed quantity and rate may be rounded. A small arithmetic difference is not permission to overwrite the printed amount.
