What this teaches
Say what goes in, what comes out and what is not allowed, and the sums follow.
- "how many people and days, and the cost of transport, lodging, food and activities" lists every input.
- "the total and the cost per person" names both results.
- "Don't let me enter negative numbers" is a rule the page enforces as you type.
