                 1         CREATE A SPREADSHEET












              In  our daily  lives and  at  work,  we  often  need  to  do  different  types
              of calculations. We use various methods based on the kind of
              calculations we need to perform. Mathematical or statistical analysis,
              long calculations, comparisons between different data sets, graphical
              representation of data, etc. are the tasks that produce useful information
              and provide proper data to help decision-making. Such tasks, if done
              manually, prove to be tedious and time-consuming.
                INTRODUCTION TO SPREADSHEET APPLICATIONS

              A spreadsheet package enables you to accomplish such tasks quickly and efficiently. A spreadsheet package
              is application software that does analysis, calculations, comparisons and displays information in the required
              format like tables, charts, graphs,  etc. By using a spreadsheet  application,  a user can  arrange  data  in a
              systematic manner and can also make use of logical functions to compute and analyse the data in different
              ways. Spreadsheet packages are commonly used for keeping data, displaying organised data, generating
              results, planning budgets, making annual reports of business organisations, generating salary statements,
              doing tax calculations, etc. LibreOffice Calc, Microsoft Excel and OpenOffice Calc are the common spreadsheet
              packages that are used today.

              LibreOffice  Calc  is  the  spreadsheet  application  of  the  LibreOffice  suite.  It  has  been  developed  by  The
              Document Foundation. It is available free of cost and can be easily downloaded from www.libreoffice.org.
