### LibreOffice Calc - A Free Accounting spreadsheet program:

Spreadsheets, can also be used to line up groups and lists and sort them, but the real power of a spreadsheet comes
from the way it can recalculate a sum or formula instantly after a single value changes.

In the picture below, we can see that the value in cell D3 is the sum of cells B3 + C3. Cell D3 is selected (with the dark border)
showing the sum of 5 + 9 is 14. The actual formula for the selected cell is shown in formula bar above the actual spreadsheet - the formula bar
shows the formula for cell D3 is '=B3+C3'. If we were to change one of the values in cells B3 or C3, the value in cell D3 would be recalculated to show this result.
