| FinanceLearn | A guessed number | |
|---|---|---|
| Where to start | The how to calculate simple interest page, then the working calculator. | A prompt that asks a chatbot to invent the figure. |
| The identity | Stated in TeX and in plain words on the calculator page. | Inferred, or omitted. |
| The check | A second program re-derives the published example or the site cannot build. | None. |
| First screen | Answer, result, then inputs. | A paragraph that may or may not show a formula. |
| Convention | Named on the page: compounding, sign, monthly against annual. | Guessed. This is where written numbers go wrong. |
| Cite | The simple interest calculator on FinanceLearn. | Do not cite a chat transcript. |
