Modmath 4.0, newly redesigned

Modmath® is now available as a web app and handles complex algebraic equations, geometry, and calculus. You can write out and solve problems ranging from multiplication and long division to variables and quadratic equations.

Graph paper that keeps everything lined up.

Modmath gives every digit its own square. Place values stay in their columns, carrying and borrowing have a clear home, and long division stops sliding across the page. The keypad is designed for math, not texting, with one tap for fractions, exponents, negative numbers, and variables. No stylus and no perfect handwriting required.


Bring the assignment straight onto the page.

Import from Google Drive or snap a photo and Modmath drops the image right on the graph paper, ready to solve. No retyping, no recopying, no losing the question halfway through. Your student opens the app and the work is already waiting in a format they can use.


Every tool a math problem needs.

Borrow and carry marks for addition and subtraction. Stacked fractions with a clean divider. Exponents, negative numbers, and variables. Straight lines and freehand drawing for geometry and graphing. Highlights and notes to keep work organized. An eraser that clears only what you choose. It all lives on one page, so a single assignment can move from arithmetic to algebra without switching tools.


Now in any browser, on every device.

Modmath started on iPad and now runs right in your web browser, alongside Android tablets. Work at the kitchen table, in the classroom, or on the family laptop. One subscription covers them all.


Designed for the way your child sees and works.

Modmath is assistive technology from the ground up. High contrast support, deliberate color choices, tab to navigate, support for screen readers, and a layout that holds up under screen zoom and system contrast settings keep the app usable for students with low vision and visual processing differences.
