Five worked examples

  1. Average inputs, average output — the everyday case Discount Calculator is built for.
  2. Edge case: very low input — what Discount Calculator returns when the inputs are at the low end of normal.
  3. Edge case: very high input — same idea, top end. Useful for understanding the range.
  4. Mismatched units — what happens if you enter pounds where Discount Calculator expects kilograms. (Spoiler: it doesn't blow up; it just gives the wrong answer.)
  5. Round-trip check — feeding the output back as input. Confirms the math.

Each of these takes 10 seconds in Discount Calculator. Worth running through them once to build intuition for what's "normal" for the formula.
