Entering Mathematical Notation
Mathematical symbols and two-dimensional notation can be entered either from the keyboard or by using controllers.
The following keystrokes can be used for two-dimensional input.
Practice entering a formula by going through these steps:
1. x 6
3. +1 /
4. 2 x
5. + a - 1
Any part of a two-dimensional formula can be selected and edited.
Matrices can be entered via the commands listed under the Lists and Matrices Creation menu. In the dialog box, specify the desired number of rows and columns and then click Paste.
Matrices can also be entered directly from the keyboard.
Every special character in CalculationCenter has a full name, such as \ [Alpha]. Many characters also have short aliases using the key.
Practice entering special characters by going through these steps:
1. \ [Alpha]
2. + b
appears on the screen as ? and disappears when the substitution occurs.

The Characters controller in the File Open Controller submenu lists many special characters. Move your cursor over any character to view its full name in the border of the controller.
