Entering Mathematical Notation
Mathematical symbols and two-dimensional notation can be entered from the keyboard as well as through palettes.
You can use the following keystrokes for two-dimensional input.
You can use 6 as an alternative to ^ ; on some non-U.S. keyboards, you may have to use 6 (see International keyboards).
Practice entering a formula by going through these steps.
1. x ^
3. + 1 /
4. 2 x
5. + a _ 1
Any part of a two-dimensional formula can be selected and edited.
Tables and Matrices
Tables and matrices can be entered using the command Input Create Table/Matrix/Palette. In the dialog box, specify the number of rows and columns. Press to fill in successive entries.
Tables can also be entered directly from the keyboard.
To display tables as matrices, type parentheses around them.
Every special character in Mathematica has a full name, such as \[Alpha]. Common characters also have short aliases using the key.
Practice entering special characters in either of these ways:
appears on the screen as and disappears when the substitution occurs.
