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.

by Filip Finodeyev
The most important daily-use software for engineers. Far more powerful than actual Mathcad Prime. I actually use more SMath Studio than MS Excel at work. Thank you, Andrey, for this GEM.

by Alvaro Gavilán Rojas
Thanks Andrey Ivashov for this wonderful tool that you provided. It is designed very well and the best opensource alternative to MathCAD available.

by Walter
Excellent program. Thanks to his author for freely sharing such an amazing piece of software. Thumbs up.

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

by Bob Johansson P.Eng.
Imagine combining Microsoft Word with the ability to compute every time you press equals. Best application for your engineering documentation needs!

by Michael James Quidilla
As a Civil Engineering professor, I've realized to be hard to find a software suitable for both introductory and advanced subjects. SMath is the only free software I know to get the job done. Try it out.

by João Felipe Melo
Brilliant program. I have MathCAD but as they have gone for subscription based I am discontinuing that. Until now I have not found any design calculation that I cannot make using SMath Studio. I recommend to all of my customers to forget all spread sheet based calculations and go for SMath Studio. I have developed my own specialty engineering software and know how much work that is. Thank You Andrey.

by Jouko Tolonen
Herramienta poderosa y versatil tanto en el ambito profesional, como academico. Un trabajo muy brillante.

by Sergio OLarte
Probably the best free math program out there. As a mechanical engineering student, so many calculations can be almost entirely automated using SMath Studio.

I have tried with some major fonts I possess. Some fonts still have glitches. I wouldn't mind or notice this if courier new wouldn't have this bug. Because it was one and only font on older releases, most of my documents have courier new as solitary font. Regards

It is available in the extension manager as "example" in three languages: German, English, Polish. Work on Portugese is in progress. The guide has a section on symbolic equation solving with Maxima. It is tested with Maxima 5.44.0.

Сейчас же эти формулы совершенно нечитаемы. Можно это как то исправить?

Учитывая, что известные мне PDF принтеры выводят изображение нормально и что в программе давно не менялось ничего связанного с отрисовкой формул мне кажется что проблема в том PDF принтере, что вы используете.

Уже долгое время (лет 9-10) пользуюсь принтером pdf24. Возможно в каком то из обновлений этого принтера что то было изменено. На работе других программ не отразилось. Какой pdf принтер посоветуете, чтобы корректно печаталось? Буду им пользоваться тогда при печати из Smath Studio.
