Each page on Quadratic Formula goes through the same steps.
- Planning. We look at what students search for and what school syllabuses cover, and plan one page per topic so pages do not repeat each other.
- Drafting. AI writing tools help us produce first drafts. A person then reads every page, checks it and edits the text before it is published.
- Checking. We work every example again in code, check each formula against standard school textbooks and test the calculators against the worked examples.
- Tools and PDFs. Calculators and downloads are built and tested by us. They run in your browser and store nothing.
- Updates. When readers report an error or a syllabus changes, we review the page and update it.
