[Blindmath] Techniques for taking Algebra through Calculus?

Hi all, a few words about LEAN Math

It has been some time since I released the last beta of LEAN, because I was finding the original architecture to be nearly impossible to repair and maintain. I have totally rewritten LEAN, making it much more robust. I am not a very competent software developer, and unfortunately it was pretty evident in LEAN I. The new version has been working well for months in audio, but I have some problems making the right information show on braille displays. I am hindered because I am not a good braille reader myself and don't usually use a braille display. However if there are people who would like to use it in audio, I would be happy to put it up for download.

For those of you who don't know LEAN, it is an efficient way for blind people to write math, and it includes a number of nice little functions that help you when you are solving algebraic equations. LEAN presently works only with the MathType application in MS Word, so you would need MS Word and MathType (available from dessci.com). LEAN creates standard MathType equations, so its output is completely mainstream. It can be used to read math in MS Word, but there are lots of ways now to read math in MS Word, so please regard LEAN as a way to write math. There are not very many ways to write math as you know. LEAN will be a free application for blind end users. ViewPlus will eventually put LEAN on the market and sell it and support packages at modest cost to institutions.

You can use LEANMath accessible math editor of ViewPlus to write and create accessible math documents with MSWord and MathType.  You can contact Sir John Gardner about LEANMath.
