3. • Spreadsheet is the computer equivalent of
a paper ledger sheet. It consists of a grid
made from columns and rows. It is an
environment that can make number
manipulation easy and somewhat
painless.

4. • A spreadsheet is simply a means of
tracking and manipulating numbers by
organizing them into rows and columns.
Spreadsheet software allows the
computer to manipulate the rows and
columns, make calculations and evaluate
algebraic formulas. Popular spreadsheet
programs include Microsoft Excel, CALC,
Lotus 1-2-3 etc..
• An electronic Spreadsheet is a computer
software program developed to ease time-
consuming numeric calculations like
grades, budgets, etc.

5. Computerized spreadsheets can calculate data easily,
accurately, and efficiently. Large numbers can be
added, subtracted, multiplied, and divided. When new
information is inserted into an existing spreadsheet,
revised calculations are performed automatically.
Spreadsheets can make your life easier by:
• Increasing the ease and speed of calculating
• Making it easy to modify information and recalculate
automatically
• Providing the ability to visually display numeric data
as a chart or graph.
• Providing the ability to incorporate numeric data into
another software application.

6. • Grade roll sheets
• Budgets
• Inventory
• Graphs for lessons plans
• Checkbook register
• Calendar
• “bean counting”
• Quantitative data tracking (forecasting
and analysis, statistics)
• Probabilities

7. • Keeping track of temperatures in a science
projects
• Logging weather points
• Drill and practice (math)
• Classification (animal species)
• Time lines/history
• Calculating Grades
• Keeping track of books students’ have read
• Graphs and Charts
• Simple Bookkeeping (TLE)
• Math

9. • It is a spreadsheet program designed to create,
organize, and analyze data.
• It is a very powerful tool for day to day business
activities such as preparing a simple invoice,
making an office form or managing a complex
accounting ledger. With Microsoft Excel, these
activities have been greatly facilitated.
• Learning the basic of excel is analogous to
investing in easy and simple tools that can make
us more efficient in our work thus enhance our
productivity.

10. • Design business forms
• Create a chart
• Sort list
• Prepare monthly sales and
expense reports
• Prepare product inventory
• Make loan payment schedule

13. The Formula Bar – made up of name box and
formula bar. It displays the contents of the active cell.
• Status Bar – its job is to let you know what’s going on –
what the status is
The Standard Toolbar
The Formatting Toolbar

14. • WORKBOOK – the file in which you work and
store your data. It contains one or more worksheet.
It is the basic document for excel. Its filename uses
the extension xls, from Excel spreadsheet.
• WORKSHEET – a single sheet of data. One or
more worksheets make a workbook. The maximum
number of worksheets in a workbook can have up
to 255 worksheets. A worksheet can have 256
columns and 65, 536 rows with up to 32,000
characters in a single cell.
• WORKBOOK WINDOW – The document window
in an Excel window.

15. • CELL – Intersection of a row and a column on a
worksheet.
• SHEET TAB – Each worksheet has a tab at the
bottom of the workbook window with the name of the
worksheet on it.
• ACTIVE WORKSHEET – The worksheet that receives
your keystrokes and commands. It has a white tab and
its name is bold.
• WORKSPACE – The area below the toolbars that
holds your documents.
• ACTIVE CELL – has a dark border around it and the
row and column headers are raised, like buttons. This
is the cell that receives your keystrokes and
commands

16. • COLUMNS – Named with letters in the following patterns:
A, B, C,…Z, AA,AB,AC,.. AZ,BA,BB,BC,..BZ,
CA,…IA,IB,…IV, which is the last possible column.
• ROWS – Named with numbers from 1 to 65, 536
• HEADINGS – the gray buttons at the top of columns and
at the left end of rows
• CELL REFERENCE OR RELATIVE REFERENCE – The
usual way we refer to a cell, using the letter of the cell’s
column followed by the number of the cell’s row.
• NAME BOX – used to display cell references and to give
and display cell names.
• FORMULA - looks like an algebra equation, it includes
the addresses of the cells whose values will be
manipulated with appropriate operands placed in
between. It must begin with an equal sign “=“.

formula bar
cell
A1:A3 is called the cell range. This shows the
cells included in computing the function
=SUM(A1:A3) is called a function, which is a
pre-written formula in Excel.

20. What you have just done is called
autofill. Autofill makes life easier
and can cut your work time in half.

21. • Formulas: Mathematical Equations
=A1+A2+A3
=(A1+A2+A3)/3
= (A1*A2)/A3
=A1-A2
• Functions: Pre-written Formulas
=SUM(A1:A3)
=AVERAGE(A1:A3)
ALWAYS REMEMBER THE “=“ SIGN IN THE
BEGINNING OF A FORMULA OR FUNCTION!!!!

23. =AVERAGE(D4:F4)
=0.2*G4+0.3*K4+0.5*N4
=RANK(O4,O$4:O$23,0)
=IF(O4>=80,"PASS","FAIL")
The $ sign is to signify ABSOLUTE CELL REFERENCE. When you want a formula or
function to constantly refer to one particular cell, even when you move or copy the
formula, you use absolute cell referencing.
