Spreadsheet App - HP Prime Graphing Calculator Quick Start Manual

Spreadsheet App

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 . The app opens
Spreadsheet
in Numeric view. (There is no Plot or Symbolic view.)
Navigation, selection and gestures
You can move about a spreadsheet by using the cursor keys, by swiping, or by tapping and specifying the cell you want
to move to. You select a cell simply by moving to it. You can also select an entire column—by tapping the column letter—and
select an entire row (by tapping the row number). You can even select the entire spreadsheet: just tap on the unnumbered cell at
the top-left corner of the spreadsheet. (It has the HP logo in it.)
A block of cells can be selected by pressing down on a cell that will be a corner cell of the selection and, after a second,
dragging your finger to the diagonally opposite cell. You can also select a block of cells by moving to a corner cell, tapping
and using the cursor keys to move to the diagonally opposite cell. Tapping on or another cell deselects the block.
Entering content
A cell can contain any valid calculator object: a real number (3.14), a complex number (a + ib), an integer (#1Ah), a list ({1, 2}),
a matrix or vector([1, 2]), a string ("text"), a unit (2_m) or an expression (that is, a formula). Move to the cell you want to add
content to and start entering the content as you would in Home view. Press E when you have finished. You can also enter
content into a number of cells with a single entry. Just select the cells, enter the content—for example, =Row*3—and press
E .
What you enter on the entry line is evaluated as soon as you press E , with the result placed in the cell or cells. However, if
you want to retain the underlying formula, precede it with S. . For example, suppose that want to add cell A1 (which
contains 7) to cell B2 (which contains 12). Entering A1 + B2 E in, say, A4 yields19, as does entering S. A1 + B2
in A5. However, if the value in A1 (or B2) changes, the value in A5 changes but not the value in A4. This is because the
expression (or formula) was retained in A5. To see if a cell contains just the value shown in it or also an underlying formula that
generates the value, move your cursor to the cell. The entry line shows a formula if there is one.
