4 Notebooks and DocumentsDoing Computations in NotebooksA typical Mathematica notebook containing text, graphics and Mathematica expressions. Thebrackets on the right indicate the extent of each cell.Mathematica notebooks are structured interactive documents that are organized into asequence of cells. Each cell may contain text, graphics, sounds or Mathematica expressions inany combination. When a notebook is displayed on the screen, the extent of each cell is indicatedby a bracket on the right.The notebook front end for Mathematica provides many ways to enter and edit the material in anotebook. Some of these ways will be standard to whatever computer system or graphicalinterface you are using. Others are specific to Mathematica.Shift +Returnsend a cell of input to the Mathematica kernelDoing a computation in a Mathematica notebook.Once you have prepared the material in a cell, you can send it as input to the Mathematicakernel simply by pressing Shift +Return. The kernel will send back whatever output is gener-
