• Math notation is displayed exactly as it will appear, either printed or rendered by a browser.
• Many useful math symbols, such as square root, greek letters, fraction signs, etc., are available.
• Equations use a monospaced math font.

LiteralMath is a text editor with two additional capabilities: 1. Math notation; 2. Hypertext. Math notation and hypertext open the field of web math to students, teachers, researchers, people who need to communicate math on the internet. It is aimed at the high school / college environment. We produce not only text, but also clickable hypertext, i.e., links to other web documents. |

This screenshot shows that: • Math notation is displayed exactly as it will appear, either printed or rendered by a browser. • Many useful math symbols, such as square root, greek letters, fraction signs, etc., are available. • Equations use a monospaced math font. |
| LiteralMath owes its simplicity to nine internal monospaced fonts: this is the best way to ensure horizontal and vertical alignment of symbols, as shown on the example at right. The matrix brackets are made of adjoining line drawing characters. Users deal with one collective font named LiteralMath Notation. |
|
| The editor processes rich text files in the .rtf format known to Wordpad, Word. It also generates .html files that faithfully reproduce the source. Browsers render math notation at the speed of text. |
LiteralMath may be used to apply math notation, hypertext, on existing .rtf texts from other editors, notably Wordpad. |

 The fundamental theorem of calculus is seen above from the editor screen, and, at left, as rendered by Internet Explorer. Our approach to math notation differs from traditional typography. Informal assignments, lecture notes, term papers, don't need the rigors of desktop publishing. The proposed MathML web math standard is a tremendous challenge to people's minds and browser performance. LiteralMath expresses math with simplicity, clarity, and efficiency. |
| Line drawing characters let us build brackets, braces, arrows, of arbitrary size. The example illustrates simple box drawing. | 
|
| To specify a hypertext link, we use source and destination anchors. A source anchor defines a clickable piece of text; a destination anchor tells the browser where to go as a result of clicking. The screenshot below shows anchor buttons which make the specification of links very intuitive, freeing the user from coding in html. It is also possible to write html tags: among other things, this is useful for including images from other software. |
|
The user interface is similar to Wordpad's. With special buttons, equation writing is as simple as typing text. |
| LiteralMath 2.5 is free.
I expected to make tons of money with this program, of course it didn't happen. The reward is watching it being steadly downloaded by students and teachers from all over the globe, and listening to their feedback. Special thanks to dozens of download sites where LiteralMath has been awarded four or five stars. This is a bilingual English / Portuguese edition. (English | Português) Requirements: • PC compatible, 32MB memory; • Windows 98, 2000, XP; • About Vista: to be honest, there have been reports of LiteralMath freezing under Vista; on the other hand, the program performed very well when run with Vista by the author. The program poses no risk at all, so you may safely install it on your Vista system, and hope for the best. Good Luck! • Generated html is compatible with Internet Explorer and Mozilla Firefox. |
The nine internal fonts that comprise LiteralMath Notation are the most important and essential requirement. This page is illustrated with screenshots, rather than generated html, because we assume that the software hasn't yet been installed on our visitor's system. When we publish an html page containing LiteralMath Notation, we cannot be sure that readers have those fonts. From version 2.4 on, the generated html will first check whether LiteralMath is installed on the client system. If not installed, then the reader will be invited to visit LiteralMath's site in order to download and install the program before viewing the page contents. |
