You can enter superscripts or subscripts for variables in one of these ways:
| • | From the data entry box, enter the expression you want sub/superscripted, highlight the terms and click the Subscript  or Superscript  button. |
| • | From the data entry box, click the Sub/Superscript button and type the values into the grey boxes. |
Note: Make sure the cursor is positioned at the left side of the gray box before typing the sub/superscript.
| • | Another way to make a subscript is to use square brackets - |
A[1] = A1
