|| Welcome to the Spoken tutorial on LibreOffice Calc – Basics of Data Manipulation.

|| In this tutorial we will learn about:

||Introduction to basics of Formula

||Sorting by Columns

||Basics of Filtering Data

|| Here we are using GNU/Linux as our operating system and  LibreOffice Suite version 3.3.4

||In a spreadsheet, the variables are cell locations that hold the data needed for the equation to be completed.

|| In our “personal finance tracker.ods” file, let us see how to add the cost of all the expenses mentioned under the heading, “Cost”.

|| We shall give one more heading as “SUM TOTAL” just under “Miscellaneous”.

||And we shall click on the cell A8 and give the serial number as “7”.

|| Now lets click on cell number “C8” where we want to display the total of the costs.

|| In order to add all the costs, we’ll type“is equal to SUM” and within braces the range of columns to be added,that is,”C3 colon C7”.

||You see that all the items under “Cost” gets added.

|| Now lets learn how to subtract in Calc.

|| If we want to subtract the cost of “House Rent” and “ Electricity Bill”, and display it in the cell referenced as A9, simply click on the A9 cell first.

|| Now in this cell, type “is equal to” and within braces the respective cell references, that is, “C3 minus C4”.

|| We see that the cost in the two cell references get subtracted and the result is displayed in cell number A9.

||Lets undo the changes.

|| Another basic operation in a spreadsheet is finding the “Average” of numbers.

|| Lets give the heading as “Average” just below the “SUM TOTAL” cell.

|| So lets click on the “C9” cell.

||Now we type “is equal to” Average and Cost within braces.

||Lets undo the changes.

||Let us now learn how to “Sort” data in a Calc spreadsheet.  

||In Calc, you can sort the data using upto three criteria, which are then applied one after another.

|| Lets say, we want to sort the data under the heading “Costs” in the ascending order.   

||So first, we highlight the cells to be sorted by clicking on the cell “Cost”.

|| Now holding down the left mouse button, drag it along the column till the end of the cell which says “2000”.

|| Now click on the “Data” option in the menu bar and then click on “Sort”.

||Next Select “Current Selection”

|| You see that a dialog box appears with tabs as “Sort criteria” and “Options”.

|| In the “Sort criteria” tab, select “Cost” in the “Sort by” field.

||In order to sort the “Cost” in ascending order, click on the “Ascending” option just next to it.

|| Now click on the “OK” button.

|| Similarly, to sort in the descending order, click on “Descending” and then click on the “OK” button.

||Let us Undo the changes

|| Lets say, we want to sort the serial numbers as well as the cost.   

||So first select these columns as we did earlier.

|| Now click on the “Data” option in the menu bar and then click on “Sort”.

|| In the dialog box which appears, first select “Cost” in the “Sort by” field.

||Then select “SN” in the “Then by” field.

|| Click on “ Descending” in both the options near them and then click on the “OK” button.

||Lets Undo the changes

|| Now lets learn how to filter data in LibreOffice Calc.

||A filter is a list of conditions that each entry has to meet in order to be displayed.

|| In order to apply a filter in the spreadsheet, lets click on the cell named “Item”.

||Now click on the “Data” option in the menu bar and then click on “Filter”.

|| Click on the “AutoFilter” option in the pop up menu.

||Click on the down arrow on the cell named “Item”.

|| Now suppose if you want to display only the data related to “Electricity Bill”.

||So click on the “Electricity Bill” option.

|| In order to view all the data, again click on the downward arrow on the cell named ”Item” and click on “All”.

|| Apart from “AutoFilter”, there are two more filter options namely “Standard Filter” and “Advanced Filter” which we will learn about in the later stages of this series.
