Answer: tracking and manipulating data.
Explanation: A spreadsheet is nothing more than a large ledger like the ones accountants and office workers used years ago. It was a ruled paper that data and information was entered on in order to keep track of money, inventory, and other information. Adding or subtracting from one column would change the totals and values overall. Now, with computers we have the electronic version and store the data on disc, flash drive or other connected media.
