The “upgrade” button is always there, front and center, as are menus and icons for the non-included features, with tooltips encouraging you to upgrade. Mathcad Express never lets you forget that PTC wants you to upgrade to Mathcad Prime. But I really miss some of Mathcad Prime’s most valuable features, including symbolic solving, the block solver, and advanced plots. In my testing of Mathcad Express, I found that its capabilities are sufficient to make it a practical alternative to Excel for most straightforward math problems. Here are the major differences between Express and Prime: ![]() It’s a harder question to answer than you might expect. The important question is this: Has PTC included enough capability in Mathcad Express to make it worth getting excited about? There is a catch, as you might imagine: Some of the functionality in the full version (which is called Mathcad Prime) isn’t included in Mathcad Express. ![]() Free, as in “free beer.” Free, as in “the software license never expires.” PTC has just released a version of the software, called Mathcad Express, that is free. ![]() Here’s a splashy video that shows what can be done with Mathcad: It’s one of those “just right” programs for engineers: It’s far better for doing engineering calculations than Excel, but is a lot easier to learn and use than Matlab. Mathcad, from PTC, is one of my favorite computer math systems.
