### Theory:

worksheet is an area where you do all the tasks. You can enter and edit data in a worksheet. A combination of one or more worksheets forms a workbook.

To enter the content in the worksheet created:
• Click the LibreOffice Calc Spreadsheets from the LibreOffice Start Centre.
• By default, you always get a workbook (sheet $$1$$) when you open the LibreOffice Calc application.
• Enter the content in the LibreOffice Calc Spreadsheet.
• You can modify content in the Calc sheet by moving the cursor to that particular cell.
• The information will be displayed in the formula bar.
• Click on the text in the formula bar and make changes.
• You can also modify the text by double-clicking on the cell.
