Final answer:
To change how a value appears in a spreadsheet cell, you need to format the cell.
Step-by-step explanation:
To change how a value appears in a spreadsheet cell, you need to format the cell. Formatting allows you to change the appearance of the value without altering its underlying data. In the case of currency, you can apply a currency format to a cell to display the dollar sign ($).
For example, in Microsoft Excel, you can select the cell or range of cells that you want to format, go to the 'Number' tab in the 'Format Cells' dialog, select 'Currency' under 'Category', and choose the desired currency symbol.
By changing the format of the cell, you can control how values are displayed, including adding symbols, changing number formats, applying date and time formats, and more.
