 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

 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.
