Controls:

With consecutive pushing of this button you can choose: "1", delimiter of the number ",", "square root - sqrt", "n-th root - nthroot", "integral - int", "function to find roots of equations - solve". To lock any variant just stop pushing this button 1 second.
-
With consecutive pushing of this button you can choose: "number related to the button", "symbols related to this button". To lock any variant just stop pushing this button 1 second.

With consecutive pushing of this button you can choose: "plus operator", "minus operator", "multiplication operator", "division operator", "exponentiation operator", "plus/minus operator", "factorial", "vector multiplication operator". Also with this pushed button you can highlight the part of equation by using Left/Right buttons.

By "clicking" on this button program will numerically calculate equation (this means "="); by pushing button more than 0,4 sec. program will symbolically calculate equation (this means "->"). Also, if the cursor located on the right of the not defined variable or not defined function this button will create a definition operator (this means ":=" ).

Removing last character (Backspace). In the mathematical reference book this button means "Back".

Thanks! this piece of software is very useful for me.

Felipe.

Wow! well done! looks promising :-)
I will love to work with it in parallel with my Mathcad in order to test it.
Any planes for an Android version? I don't think you have any compatitors there...

I love this piece of work too, for my windows smartphone HTC HD2,
my question is, wether there was some progress in development of free? import tools to read in MATHCAD mcd files;
would be happy when someone could write a short resume, how-to-do, for the actual state,

much thanks

Just got it on my windows notebook, and getting it on my linux stationary, but can I get it on my android (HTC desire S) whitout spending $399?????

was trying to get the linux version, but cant get to download mono, just filling in forms

Glad to introduce a new help document for beginners who makes first steps using SMath Studio:

Wrote

SmathPrimer.pdf is in-part a compilation of existing documents (edited as I saw fit) plus some of my own work. I tried to cover all the problem I had as I started to learn SMath. It is primarily for people who are new to SMath and would like some notes all in one place.

Document added to the main download page:
