Open NB File
An NB file extension is a structured document created by Mathematica, an application used for mathematical and scientific calculation.
More about Mathematica
Mathematica is a program used in scientific, engineering, mathematical, and computational areas.
It was originally conceived by Stephen Wolfram, who continues to lead the group of mathematicians and programmers developing the product at Wolfram Research, a Champaign, Illinois-based company.
Commonly thought of as a computer algebra system, Mathematica is also a powerful general-purpose programming language.
Unlike other computer algebra systems, for example Maxima or Maple, Mathematica tries to use the transformation rules it knows at all times as much as possible, trying to reach a stable point.
Role of the NB file in Mathematica
The NB file contains text, images, audio, functions, and interactive user interface elements.
NB files allow you to view the mathematical results in an interactive document.
NB files are saved in a plain text format. Your data is organized in cells, similar to a standard spreadsheet.
Notebooks can be exported to many different file formats, including raster graphics, GIS, compressed, and spreadsheet formats.
The default styles NB file, named 'DefaultStyles.nb' is used to customize the new notebooks.
Notebooks can be opened using the NotebookOpen command within a Mathematica function.
