If you are thinking about getting MathCAD for your business or personal use you may want to try SMath Studio first. SMath Studio is a free math program with easy to use intuitive "paper-like" interface. If SMath Studio meets your needs then look no further and consider donating to promote further development of this great program. On the SMath Studio forum, the developer and forum community are very receptive to help questions, bug reports, and feature requests.

As a civil engineer, over the years I have frequently used MathCAD for not only performing but also documenting calculations. With PTC dropping perpetual licensing, my recommendation to all the junior engineers I train is to give SMath Studio a serious look. While not a turnkey replacement for MathCAD, it provides most of the functionality and power at an incredible price. Already a wonderful program filling a key niche spot between a numerical calculator like Octave, and a CAS like Maxima, the expanding plugin and 3rd party development is on the rise and this project's future keeps getting even brighter. Much consideration must be given by any engineer or business before they settle on a software for adopting into the workflow. Although not open-source in the strictest sense, the development community is similar to what you would find in any first class OSS software project. The current owner of the SMath Project has also agreed to release the source code under open source license should he not be able to continue the project. So do not let the cost (your time) of learning SMath Studio and migrating your MathCAD computation sheets scare you. This project is here to stay.

Smath is a very simple program to use. It´s similar to Mathcad and it´s free. I use it for my spreedsheets at work. I recommend it, without a doubt.

by Joaquín Guraiib
Great program for conducting engineering calculations. The ability to insert text blocks and pictures makes it perfect for both computation and communication of the results to colleagues.

Buenísima aplicación.

by Nicolás Troncoso
Great free software! I am enjoying watching its progress and use every day for reinforced concrete calculations and client presentations! Hope it gorows well"

by Thomas Carmona
Andrey has given us back the joy of Math that we experimented with Mathcad some thirty years ago, until PTC messed it all up. A fantastic achievement! And free! I am beginning to use it intensively to help my engineering students.

Thank you for SMath. It's been a life saver.

I get a strange error: The context menu doesn't close and stick in the foreground. This is triggered by trying to zoom the canvas by ctrl-drag middle mouse button (Lenovo thinkpad trackpoint). The menu windows don't vanish when the program is closed. They only vanish if the temporary terminal window is closed as well. There is no way to zoom the canvas with trackpoint or trackpad. I have to use the status bar zoom menu for zooming. Under Windows I can use two-finger guestures on the trackpad to zoom. This may be due to insufficient hardware support in the linux box. BTW 6580 crashed when I started typing to the canvas. This problem is solved now even though my mono might not be up to date.
