Mathematica Tutorial: Notebooks And Documents - Wolfram Research

2 Notebooks and DocumentsA notebook mixing text, graphics and Mathematica input and output.When Mathematica is first started, it displays an empty notebook with a blinking cursor. Youcan start typing right away. Mathematica by default will interpret your text as input. You enterMathematica input into the notebook, then type Shift +Return to make Mathematica processyour input. (To type Shift +Return, hold down the Shift key, then press Return.) You can usethe standard editing features of your graphical interface to prepare your input, which may goon for several lines. Shift +Return tells Mathematica that you have finished your input. If yourkeyboard has a numeric keypad, you can use its Enter key instead of Shift +Return.
