Spreadsheets and Modelling
A spreadsheet is a piece of software which is used to carry out calculations. Spreadsheets are very common in business, as they are excellent for handling data such as sales, engineering or financial data. You can learn, and answer questions about them here.
A model allows you to try out different scenarios to see what would happen if you made a change without any of the risks of actually having to do them in real life.
A model tries to be as close as possible to the real-life situation but its accuracy depends on how carefully it was built.
Models can be as simple as a basic financial spreadsheet or as complex as one used by architects to test out the strength of a bridge in the event of an earthquake. Try for yourself here
