Free mathematics software for mac

Adding Three Fractions 1.0 is known as a free yet very useful program taken from a CD-ROM collection of over 200 mathematics puzzles, available on the developer's Web site. Developed by a veteran teacher, these visually-oriented puzzle games have a simple interface and are designed to provide math problems in context to middle-school (grades five through nine) students.

In this particular puzzle, students choose one of two types of problems: ruler fractions (halves, fourths, eighths, sixteenths) or regular fractions. Students must add the given three fractions. Every problem is illustrated with an interactive sketch. You can view a screenshot of this program by clicking here.

This free Yahoo! widget tries to show you the beauty of mathematics, more precisely the beauty of Platonic solids. You can choose between the five Platonic solids tetrahedron, hexahedron, octahedron, dodecahedron and icosahedron as well as set a few animation parameters.

Requirements:

• Yahoo! Widget Engine
• Universal Binary

DragMath is a drag and drop equation editor in the form of a Java applet. Once an expression is created the user can convert it into a variety of different linear syntax for mathematics, including MathML, LaTeX, Maple, Maxima or any user defined style.
The editor lets users build up mathematical expressions in a traditional two dimensional way, and then output the results in a correctly formed syntax. This is not so easy: mathematical notation contains some ambiguities.
The supplied output formats are MathML, LaTeX, Maple, Maxima. It is also possible to convert the expression to almost any user defined style by creating an XML file with the correct syntax data in it. Details of how to do this are included in the documentation.
Although mathematics is less dependent on language than many things, the applet loads a language file which makes it possible to translate DragMath into other languages.
DragMath has currently been translated into: Catalan, Czech, Norwegian, Polish, Portuguese (Brazilian), Dutch, English, French, German, Russian, Spanish and Swedish.

TeXShop is a very useful tool, a TeX previewer for Mac OS X, written in Cocoa.
Since pdf is a native file format on OS X, TeXShop uses "pdftex" and "pdflatex" rather than "tex" and "latex" to typeset; these programs in the standard teTeX distribution of TeX produce pdf output instead of dvi output.
TeX is a typesetting program by Donald Knuth, used extensively in mathematics, computer science, physics, economics, and other fields.
For a history of the development of TeX, see Just What Is TeX. Consult the TeX Users Group Web Site for additional information.
To use TeXShop, you need to learn TeX or LaTeX.

Enhancements
- The TeXShop/Engines/Inactive folder contains two scripts from Daniel Becker which call texcount to count active words in a TeX source file. These engines were promised in 2.25 but erroneously omitted. They are in 2.26. To obtain them, quit TeXShop and move the entire Engines folder from ~/Library/TeXShop to the Desktop. Then restart TeXShop. TeXShop will create a new Engines folder. Merge in any changes you have made in the old Engines folder on the desktop to the new folder.
- Juan Luis Varona sent new Program and Encoding macros which display the various choices, so it is not necessarily to look up the wording of these choices. A few days later, Ramon M. Figueroa-Centeno send similar but fancier macros. Ramons macros are now in TeXShop. To obtain them, quit TeXShop and move the entire Macros folder from ~/Library/TeXShop to the Desktop. Then restart TeXShop. TeXShop will create a new Macros folder. Merge in any changes you made to the old Macros on the desktop to the new copy, using the Macro Editor.
- A memory leak introduced by the code to split the Preview window in 2.25 is fixed. The bug was similar to the old flaw in PDFKit which caused memory to be gradually used up when typesetting a document many times, but this time the bug was caused by me.
- A bug in the zoom code for the preview window when using multiple monitors is fixed.
- A bug which caused TeXShop to ignore a "% !TEX TS-program = ..." command when typesetting from a file with an associated root file is fixed.
- The French localization is improved.
- A localization error caused the "Split Window" icon on the Preview Window toolbar to display strange text. This is fixed.
- A bug caused the Preview Windows toolbar to vanish temporarily if the user tried to move certain text portions of the toolbar. This is fixed.
- One of the keyboard zoom shortcuts acted only on the top portion of the Preview window when split. This is fixed.
- The TeX mdimporter code distributed with TeXShop in 2.25 contained only i386 code. Now it contains code for both PPC and i386.

GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists.
The software aims to provide a unified and user friendly framework for editing structured documents with different types of content (text, graphics, mathematics, interactive content, etc.).
The rendering engine uses high-quality typesetting algorithms so as to produce professionally looking documents, which can either be printed out or presented from a laptop.
The software includes a text editor with support for mathematical formulas, a small technical picture editor and a tool for making presentations from a laptop. Moreover, TeXmacs can be used as an interface for many external systems for computer algebra, numerical analysis, statistics, etc.
New presentation styles can be written by the user and new features can be added to the editor using the Scheme extension language. A native spreadsheet and tools for collaborative authoring are planned for later.
TeXmacs runs on all major Unix platforms and Windows. Documents can be saved in TeXmacs, Xml or Scheme format and printed as Postscript or Pdf files. Converters exist for TeX/LaTeX and Html/Mathml.
TeXmacs currently runs on most Unix systems, Mac OS X (using Fink), and Windows (using Cygwin).
System requirements:
- 200MHz processor and 32Mb of memory, but >1GHz and >128Mb are recommended.
- TeX/LaTeX distribution on your system
- Guile/Scheme extension language (to compile TeXmacs from source)
