DysCalculator

DysCalculator is designed for people with dyscalculia and related learning differences. It reflects how these individuals perceive and work with numbers, using language, visual, and spatial cues to build number sense, confidence, and understanding.

Developed from years of research into maths accessibility, DysCalculator simplifies numerical tasks by adapting to how users interact with numbers and technology.

Key features:

• Numbers arranged by magnitude (0 to 9)
• Operators ordered by precedence (PEMDAS/BODMAS)
• Natural-order input (e.g. 2 + 3 = for addition)
• Visual step-by-step workings to explain calculation logic
• Solve for unknowns (e.g. 3 + ? = 5)
• Solve time calculations (e.g. elapsed time, differences)
• Pictograms for time, fractions, and percentages
• Tax and percentage calculators with preset values

Customisable:

• Personal greetings
• Alternate key labels (e.g. “plus” or “and” for +)
• OpenDyslexic font for dyslexic users
• Irlen-style shading to improve legibility
• Multiple languages, including te reo Māori and German
• Read keys aloud
• Different keyboard layouts and fixed decimal formats

DysCalculator doesn’t just give answers – it helps everyone understand how maths works. Whether you're using it independently, in a classroom, or as a support tool, it’s built to make maths more accessible, intuitive, and less intimidating.
