A program for plotting high-quality 2D graphs of equations, inequalities, and tables. Lets you perform regression analysis and various calculations. Up to 30 graphs on one coordinate plane (in one document); multiple-document interface - the amount of simultaneously opened documents is limited only by the amount of free memory. Supported graph types: Y(x) and X(y); graphs of tables; R(a) - in polar coordinates; X(t) and Y(t) - parametrical equations; f(x,y)=0 - graphs of equations; (x,y)<0 and f(x,y)>0 - graphs of inequalities (and systems of inequalities); dx/dy(x,y) and dy/dx(x,y) - slope fields. Calculus features: regression analysis (7 regression types and ability to automatically choose a regression type); obtaining intersections; analytical derivation; determination of the equation of a tangent and its plotting; numerical integration; obtaining zeroes and extrema of functions. The graphs can be saved as BMP or EMF and exported to Word documents.

Description by the Software Developer: "The GridinSoft Notepad was made for those people that don't have enough opportunities standard notepad in OS Windows. GridinSoft Notepad contains all that is necessary for convenient and functional job with text files.

The basic opportunity of the program is syntax highlighting more than 25 formats of files (HTML, ASP, PHP, Perl, Pascal, C++, etc.).

Except for that an opportunity of preliminary viewing of the text before a print on the printer, the bookmarks, the adjusted interface and many other things."

"Good addition skills are a foundation for math and will benefit a child throughout life. While your kids enjoy playing, our game will give them invaluable mental addition practice. With our 2 player option you can join in on the fun (learning :-). When you're busy your kids can challenge the computer and try to beat their high score. Multiple difficulty levels and optional negative numbers. A simple interface and easy Tic Tac Toe based rules. Playing the game is easy. Similar to Tic-Tac-Toe, players take turns claiming squares (marking them with an 'X' or an 'O'). However, the board is larger and getting 3 squares in a row doesn't win the game. Each square has a point value displayed on it. When you claim 3 squares in a row, the total points are added to your score. Once all the squares are taken, the player with the most points wins. The challenging part of the game is deciding which square to claim on any given turn. Winning strategies require you to figure out how many points each square could be worth later in the game. Not only do you need to find squares that will give you a lot of points, you have to watch your opponent and sometimes block them from scoring. Sometimes when you're playing with negative numbers you have to avoid getting 3 in a row (if the sum is negative)." Evaluation period: 3 days.
