Description
Interactive graphs, formulas, and vocabulary for DeltaMath. A private, on-device math reference that never fills in answers. Math Lens brings interactive graphs, formulas, and vocabulary into a Chrome side panel beside your DeltaMath lesson. Explore the mathematical idea behind the problem with a reference designed to support your understanding. GRAPHS & SHAPES Choose from 28 graph and shape tools. Adjust practice functions, plot and drag points, build polygons, explore transformations, and zoom around the coordinate plane. Graphs start with separate practice values, never numbers copied from your current question. FORMULAS See recommendations for supported lesson topics or search a built-in formula library. Open a reference note for an explanation, guidance, and a separate practice example. VOCABULARY Look up mathematical terms, definitions, illustrated examples, and common mix-ups. The combined formula and vocabulary library contains more than 550 entries, covering topics from elementary math through calculus. LOCAL LESSON RECOMMENDATIONS Math Lens reads the current DeltaMath page's lesson headings, problem text, rendered math, URL without query strings, and selected lesson metadata to recommend relevant references. It processes this context on your device. New or unrecognized lessons can still use manual graph selection and reference search. PRIVACY No Math Lens account, API key, or helper server is required. The extension makes no external AI requests and has no analytics or advertising. Lesson context, searches, and graph inputs are not transmitted or saved to persistent extension storage. The reader skips answer controls and editable fields. Incidental personal details in ordinary page text may be processed locally; see the privacy policy for details. GETTING STARTED 1. Install Math Lens in desktop Chrome 116 or later. 2. Open a DeltaMath lesson. 3. Click the Math Lens toolbar icon to open the side panel. 4. Explore Graphs & Shapes, Formulas, and Vocabulary. Press Refresh if a lesson has not loaded yet. You can also select “Try an example lesson” at the bottom of the panel without signing in to DeltaMath. FOR SCHOOL CHROMEBOOKS Your school may need to allow or install the extension. Follow your teacher's rules for assignments and assessments. Math Lens does not fill answer boxes, choose answers, submit work, or bypass school device policies. Math Lens is an independent project and is not affiliated with or endorsed by DeltaMath or Google. Lesson detection depends on DeltaMath's page structure and may need updates as the site changes. ```
