A basic presentation about spreadsheets

1. Welcome to the

2. Welcome to the world of

A spreadsheet is a program that allows us
to enter data into a table. A table is
made up of rows and columns. We use
spreadsheets to organize data, make
simple and difficult calculations, and then
present the data in charts.
 We can draw bar graphs and pie charts
within seconds

3. Welcome to the world of
spreadsheets
 We cannot see the entire spreadsheet on
the screen because it is very large.
However, we can view and edit parts of it.
 Lotus 1-2-3, Microsoft Excel, and numbers
are spreadsheet programs that are
popularly used.
 The spreadsheet on the next slide tells us
how much the school spent on stationary
during a school year.

 A spreadsheet has rows and columns.
 Rows are horizontal. The numbers along the
side of the worksheet shows the rows.
 Columns are vertical. The letters across the
top of the worksheet show the columns.
 A cell is the space where a row meets a
column. We can enter data into an active
cell . We can identify an active cell by its thick
border.

6. Welcome to the world of
spreadsheets
 We refer to a cell by its cell address . The
cell address consists of the column letter
and the row number. When we write the
cell address, we must always specify the
column first and then the row.
 In the spreadsheets, columns and rows
meet at the cell address, for example:
column c and row 5 meet at the cell
address C5.

7. Welcome to the world of
spreadsheets
 Range refers to one or more cells. A range
may be a single cell or a group of cells
next to each other. We can identify range
by specifying the cell address of the first
cell and the last cell. If the range is that of
a rectangular cell, the first cell is of the
upper most left cell which is A1 and the
last cell is the lowermost right cell which is
D5. So the range is A1:D5.

8. Welcome to the world of
spreadsheets
 What you put in a cell is called cell entry.
It could be data such as words, numbers,
or formulae. Titles, columns, and row
headings are referred to as labels.
 The numbers entered into the cell are
called values. They are always aligned to
the right edge of the cell. Text is aligned
to the left edge of the cell.

9. Welcome to the world of
spreadsheets
A formula performs calculations using the
values from other cells. When a formula is
entered into a cell,= is the sign before it.
