APPLICATION OF SPREADSHEET

It can be used to track profit and losses Economists can generates growrh graphs

of country’s economy Women can manage their household

budgets .

ADVANTAGES OF SPREADSHEET

It increases the ease speed of calculating. It makes it easy to modify information and

recalculate automatically. Displays numeric data as a chart or graphs;

DISADVANTAGES OF SPREADSHEET

Spreadsheet can not process large volume of data.

It doesn’t provide much programming facilities

FUNDAMENTALS OF SPREADSHEET

Electronic spreadsheets are useful for all types of personal and business applications

Screen display of the spreadsheet divided into three areas:

1. Control panel. 2. the worksheet area.3. The status line.

1: Control panel The control panel helps user with data

entry , editing , formatting and processing activities.

Typically , a spreadsheet’s control panel usually comprises three lines:

1. Command menu2. The icon bar 3. Th data entry line.

2: WORKSHEET AREAIt is an interface for the user or area where data is entere.spreadsheet consists of columns and rows to enter data.A standard screen display usually holds about 20 rows of a worksheet,But a spreadsheet or a worksheet with more rows may, of course , be built…….

3: STATUS LINE Status line displays the active cell’s default font and other formats , the current date and time , as well as the spreadsheet’s active operating state , or mode.1. Ready mode2. Enter mode 3. Menu mode4. Edit mode5. Wait mode6. Error modeAre common modes of status line….

DIFFERENT TYPES OF DATA IN EXCEL

1) Label2) Values3) Dates4) Formula

Are the some common types of data in excel….

1: LABELLabel are used to identify a value or series of values . label are helpful in making the worksheets meaningful. Formula can not be applied on lables .

College algebra

Information technology

Basic management

2: VALUES

Values are usually numeric data typed in different cell. The values can be whole number, decimals, negative number some examples of values are 50,26.33,-12etc., A B CMarks 10 20 30

3:DATESDates are values that can be used in calculations to create new dates or calculate time intervals. An example of dates is 1/1/2016.

4:FORMULAA formula is an expression that produces some values. Formula may be very simple or extremely complex .a formula begins with = an equal sign followed by one or more values to calculate .

ENTERING FORMULA IN EXCEL

1. Click on the empty cell that will display the result of the formula.

2. Type the equal sign.=3. Type formula without any spaces

e.g.,A1+A2+A3+A4.then press the enter key. The result will appear in the cell while the formula will be displayed in the formula bar.

4. If you change any value of a cell referenced in a formula , the formula, will automatically recalculate and display the new value.

FUNCTION OF EXCEL ALL THE FORMULA IN SPREADSHEET ARE FUNCTION.Function are built-in formulas that are used to perform complicated calculations.Example :=D1+D2+D2+D3The SUM function can be used to perform this operation in a shorter way as follows:=SUM(D1:D10)

IMPORTANT FUNCTIONSCLICK function wizard button on standard toolbar(ƒX). The insert function dialog box will appear. Some important functions are as follows:

Function Example DescriptionsSUM =SUM(A1:100) The sum of cell A1

through A100AVERAGE =AVG(B1:B10) The avg of cells

B1 through B10MAX =MAX(C1:C2) Highest number

from C1 through C100

MIN = MIN(D1:D100) Lowest number from cells D1 to D100

TODAY =TODAY() Current date

SPREADSHEET COMMANDS1.Format:Most spreadsheet programs have default worksheet setting consisting of display formats for labels, value, column widths ,and so on.2. cut and copy:The cut and paste commands, as the name indicate , allow the user to change the location of data or a formula to another spreadsheet.3. Saves and open command:Worksheet stored on disk as part of an electronic spreadsheet’s save command.A saved worksheet can be opened , changed , and saved under the original filename.
