Microsoft Excel 2003

Introduction:- MS-Excel is the Spreadsheet Software. It is popular software used extensively for entering, calculating, manipulating and analysis large volumes of numerical data. 
Microsoft Excel is the most popular software for mathematical calculations. It provides facilities to spread data in tabular form consisting of rows and columns. This way data can be organized easily. Worksheet is also called Spreadsheet or Electronic sheet.
Advantage of MS-Excel
Automatic Calculations:- Excel provides many in-built functions for 'quick' and 'accurate' calculations. Result update automatically whenever data is changed.
Filtration of Required Data:- We can extract required information from a large worksheet by specifying the specifying the filtration criteria and seeing only the selected data.
Graphical Representation of Data:- Excel helps in representing our data graphically through charts; It also helps us to 'design' our data to make it look attractive. 
Automatic Analysis:- Different option offered by the Excel us to play with numbers and 'analysis' the result by changing them in different ways.
The different components of MS-Excel one by one
Workbook:- A file in MS-Excel is called Workbook. Each Excel file (Workbook) has a different but same extension of .xls.
Worksheet:- Each Workbook in MS-Excel is made of a number of Worksheets. The maximum limit of the worksheet in a workbook is 255.
Rows:- Rows are horizontal collection of cells that are represented by numbers from 1,2,3.......to 65,536. This means there are 65,536 rows in a Worksheet.
Columns:- Columns are vertical collection of cells that are represented by alphabets like A,B....Z, then AA,AB......AZ.....till 256 columns are 'labelled'. Therefore, there are 256 columns in a Worksheet.
Cells:- Cell is the 'intersection' of a rows and column. Each cell has 'label' (Name) called the cell address by which it is uniquely represented. For Ex- a cell formed at the intersection of column C and row 8 will have 'Cell Address' as C8.
It is used to store data. There are 65,536*256=16777216 cells in a single worksheet.
Active Cell:- Active Cell is the cell with a 'dark border' around it. We work in one 'active cell' at a time.
Cell Range:- Cell Range is a 'continuous' block of cells represented by the address of first and the last cells.
Functions:- Functions are 'pre-predefined' formula. Functions has three parts.
1. Equal Sign ( = )
2. Function Name
3. Function Argument or Function Parameter
Ex:- =sum(a1:a5) Here, sum is the function name and (a1:a5) its argument.
Note:- While writing a function or formula in a cell or formula bar always begin with '=' sign.
Operators:- A formula is mathematical expression which contains one or more operators. The type of calculation you want to perform is specified by an operator. Arithmetic operator and Comparison operator are two types of operator.
Arithmetic Operator:-
Arithmetic Operator
Comparison Operator:-
Comparison Operator
Note:- The result of the logical test argument is only ever "True" or "False".
Formula That Produce Error Values
Formula Excel displays an error value in a cell when it can not calculate the formula for that cell properly.
Formula Errors
How To Start MS-Excel:-
Start-->All Program-->Microsoft Office-->Microsoft Excel 2003          OR
Run-->Excel
Note:- Windows Key + R = To open run dialog box
In Excel:-
Normal & Auto fill Cursors
Auto-Fill Series:- The auto-fill feature helps us to easily and quickly generate a series of a particular order in Excel. By using Auto-fill, we are saved from 'entering' a particular sequence of numbers, months, days, manually.
Creating Custom Lists:- Custom Lists are 'auto-fill list' that have been created according to our own requirements.
To get options dialog box click on Tools -->Options-->Custom List
Editing Data:- We can edit the data that is 'entered' in the particular cell by using the F2 function key or by 'double clicking' the cell to 'activate' it to make changes to it's contents.
Selecting Data:- A Continuous Block of Cells can be 'selected' using the mouse multiple ranges can be 'selected',using the Ctrl key and the Mouse.
Note:- Press the Escape key typed data will not be not be entered in the cell.
