About the app
Monty Math is an indie app on a simple mission: make math more enjoyable and easier to actually understand.
The best way to understand something is to play with it — not copy steps off a board, but grab it, move it, and see what happens. Monty Math is built entirely around that idea. Every tool is hands-on: you drag, spin, and slide your way to the answer, and the maths reacts live as you go.
It's made by a single developer who cares about math education, with a simple goal: build the math tool they wish they'd had in school. Monty Math is free, has no ads, and always will be.
Type any equation into the input field. Each term becomes a draggable tile. Drag a term across the equals sign to move it — the sign flips automatically (+ becomes −, × becomes ÷). Tap a variable to substitute a value. Use the toolbar to apply index laws, trig identities, log rules, or complex number operations.
Drag the point around the circumference of the circle. The sin and cos lines update in real time as you move. Try sweeping through all four quadrants and watch how the signs change — it's the fastest way to understand why sin is negative in the third quadrant.
Enter any number. Drag the decimal point left or right across the digits. The scientific notation updates live — the coefficient and exponent both change as you drag. It makes the relationship between decimal position and powers of ten completely intuitive.
Monty Math is free and will stay that way. If it's been useful to you or your students, a small donation helps cover the cost of keeping it on the App Store.
