Spreadsheet
The Spreadsheet app provides
a grid of cells for you to enter
content (such as numbers, text,
expressions, and so on) and to
perform certain operations on
what you enter.
To open the Spreadsheet app,
press
I and select
Spreadsheet.
You can create any number of customized spreadsheets, each
with its own name (see “Creating an app” on page 107). You
open a customized spreadsheet in the same way: by pressing
I and selecting the particular spreadsheet.
The maximum size of any one spreadsheet is 10,000 rows by
676 columns.
The app opens in Numeric view. There is no Plot or Symbolic
view. There is a Symbolic Setup view (
SY) that enables
you to override certain system-wide settings. (See “Common
operations in Symbolic Setup view” on page 87.)
Getting started with the Spreadsheet app
Suppose you have a stall at a weekend market. You sell furniture
on consignment for their owners, taking a 10% commission for
yourself. You have to pay the landowner $100 a day to set up
your stall and you will keep the stall open until you have made
$250 for yourself.
1. Open the Spreadsheet app: Press
Press
I and select Spreadsheet.
2. Select column A. Either tap on A or use the cursor keys to
highlight the A cell (that is, the heading of the A column).
