The Best PTC Mathcad Alternative

Mathcad is a respected engineering-calculation tool where math reads like a worksheet with live units. It's paid, desktop-first, and centered on calculations rather than dynamic simulation. PolySim renders live equations too, but as interactive, time-stepping simulations you can run free in the browser.
