MathéA vs Marp Slide AI

MathéA - Accessible Scientific Calculator MathéA is a full-featured scientific calculator built from the ground up for accessibility. Designed with VoiceOver in mind, every result is not only displayed as beautifully rendered mathematics but also spoken aloud in natural language - so nothing is lost between the screen and the user. SPOKEN MATHEMATICS Every calculation produces a spoken description in natural language. Results are read in English, French, and German, covering fractions, roots, powers, integrals, and more - exactly as a teacher would say them. DISPLAY FORMATS Results appear as rendered mathematics: exact fractions, square roots, pi-forms, scientific notation, mixed numbers, prime factorisation, and degrees-minutes-seconds. Toggle between exact and decimal form instantly. WHAT MATHEA CAN CALCULATE • Arithmetic: fractions, powers, roots, factorials, percentages, GCD, LCM, integer division with remainder, powers of 10 entry • Functions: sin, cos, tan and inverses; log, ln, log base n; 10^x, e^x; square root, cube root; nPr, nCr; Abs, integer part, rounding; random number, random integer • Calculus: definite integral, derivative, summation, product • Complex numbers: full arithmetic, magnitude, argument, real and imaginary parts, conjugate; rectangular and polar display • Base-N: binary, octal, decimal, hexadecimal; bitwise NOT, AND, OR, XOR, shift • Matrices: up to 4x4; addition, subtraction, multiplication, scalar multiplication, transpose, determinant, inverse • Equation solver: simultaneous linear equations (2x2, 3x3, 4x4) • Polynomial solver: quadratic and cubic equations • Inequality solver: linear and quadratic inequalities • Statistics: one-variable and two-variable analysis; 8 regression models (linear, quadratic, cubic, quartic, logarithmic, exponential, power, inverse) • Distributions: normal, binomial, Poisson - probability density, cumulative distribution, and inverse • Function table: evaluate f(x) and g(x) over any range with any step size • Ratio solver: A:B = X:D or A:B = C:X • Verify mode: evaluate relational expressions (equal, not equal, less, greater, etc.) to True or False • Coordinate conversion: polar to rectangular and back • Angle units: degrees, radians, gradians with inline suffixes MEMORY AND USER FUNCTIONS Store values in variables A through F, x, y, z. Access the last two results via Ans and PreAns. Define custom functions f(x) and g(x) and reuse them anywhere. ACCESSIBILITY FIRST • Fully optimised for VoiceOver • All results spoken in English, French, and German • MathJax accessibility explorer for step-by-step navigation of complex expressions • ARIA live regions for instant result announcements • Large 48pt touch targets • Full keyboard and switch access support EXAM MODE One tap clears all memory, disables history and persistence, and restricts features to comply with examination regulations - no graphs, no symbolic algebra, no text storage, no network access. COMPLETELY OFFLINE All assets are bundled locally. No internet connection is ever required. No data leaves the device. INTERFACE Available in English, French, German, and Portuguese. Includes a searchable examples catalogue (90 entries across 20 categories) and a full user manual.

# Create Marp Slides with AI Marp Slide AI automatically creates slide decks in Marp Markdown from natural-language instructions. Create project proposals, business presentations, service introductions, lesson materials, seminar slides, status reports, and more from your smartphone or tablet. AI generates titles, body text, structure, and layouts. Because every slide is saved as Markdown, you can revise it with AI or edit the text yourself. Preview your slides instantly and present them directly from the app. ## Features ### Just Describe What You Need Tell AI what kind of slides you want. AI organizes your ideas and creates a complete deck with titles, content, structure, and layouts. > “Create a presentation introducing a new service.” > “Create a seven-slide business process improvement proposal.” ### Easily Revise with AI Give additional instructions to update your slides. You can revise text, structure, colors, layouts, and content length. > “Use a calm, blue-based design.” > “Shorten the text and make the key points clearer.” > “Add a summary and next steps.” ### Edit Individual Slides Select a slide and ask AI to edit only that slide while keeping the rest of the deck unchanged. > “Add a comparison table to this slide.” > “Rewrite this slide for beginners.” ### AI-Powered Improvement Suggestions Ask AI to review the whole presentation and suggest improvements. - Review slide order and overall structure - Reduce text density - Improve the title slide - Standardize wording and terminology - Suggest charts, tables, or diagrams - Add a summary and next steps - Adapt wording for the audience - Check for typos and awkward text ### Edit Freely with Marp Markdown Slides are created in Marp Markdown format. You can directly edit headings, bullet points, and other text. Experienced Markdown users can fine-tune every detail, while beginners can create and edit slides entirely through AI instructions. ### Edit Deck Settings Adjust settings that apply to the entire deck, including themes, page numbers, and slide size. You can also edit Marp front matter and styles. > “Add page numbers to every slide.” > “Use a simple business-style design.” ### Attach and Use Images Attach images and place them in your slides. Adding an image description helps AI decide where and how to use it. > “Place the attached product image on the service introduction slide.” ### Instant Preview Preview slides immediately after creating or editing them. Check the content and design as you work and refine your presentation efficiently. ### Present from the App Display completed slides as a slideshow directly in the app. Create, edit, preview, and present in one place. ### Export in Multiple Formats Export slides for sharing, printing, or further editing. - PDF - Current slide as PNG - HTML - Marp Markdown - Print - App format for later editing ### Import Existing Files Import supported slide files and continue editing them in the app. Use existing Marp Markdown or HTML files as the starting point for a new presentation. ## Use Cases - Project proposals and business plans - Product and service introductions - Sales presentations - Internal reports and process improvement proposals - Project status reports - Research and survey summaries - Lessons, lectures, seminars, and training - Company profiles and recruiting materials - Investor presentations - Portfolios and personal introductions - Markdown-based slide creation With Marp Slide AI, creating slides starts with simply describing what you need. No professional design skills or Markdown knowledge are required. Combine AI-powered generation with the flexibility of Marp Markdown to turn your ideas into presentations quickly.
