Spreadsheets for Math

When am I ever going to use a spreadsheet in math? I jest. In math, we could use a spreadsheet to analyze the manipulation of functions. For example, we could create a table and observe how the value of the function changes as the input changes. We could then refelect on why or how those changes occur.
