3. The book is the manual for mathematics and engineering students of higher educational institutions. In relation to this (and for this) the author added some detailed information which may seem to be unnesessary for those familiar with computer.

4. This book is not only on computer software, but also on life. The author made his best (the reader will judge whether successful or not) to address the problems both closely and loosely related to computers (conflicts existing in modern world, computer piracy, tax system, computer and mathematical education etc.).

5. This book is not a comprehensive reference book on Mathcad. Some readers reproach the author: Instead of simple translation and publishing of the Mathcad documentation, you rumble with fire buskets and exercise with merchant and cloth. The author replies that Chukcha is not a translator, but writer, that is, computer writer (see Ref. 15 in Exercise 7).

6. Working on the book, the author for the first time used the advantages of Internet: most of comments and suggestions on the previous releases were e-mailed. Here are three e-mail addresses of the author:

7. The author strongly recommends to read forewords to two previous releases (see below); they were also updated.
