• 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.

• 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.

• 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.

• Grade roll sheets• Budgets• Inventory• Graphs for lessons plans• Checkbook register• Calendar• “bean counting”• Quantitative data tracking (forecasting

and analysis, statistics)• Probabilities

• 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

• 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.

• Design business forms• Create a chart• Sort list• Prepare monthly sales and

expense reports• Prepare product inventory• Make loan payment schedule

• 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.

• 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

• 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 “=“.

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.

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

• 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!!!!

=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.
