Explain four cell data types in a spreadsheet.

1. Text: This data type is used to input and display alphanumeric characters, such as letters, numbers, and symbols. Text data is typically left-aligned in a cell and can be used for labels, headings, or any other type of textual information.

2. Number: This data type is used for numerical values, such as integers, decimals, percentages, and currency. Number data can be formatted in various ways, such as with commas, decimals, or currency symbols. Number data is typically right-aligned in a cell.

3. Date: This data type is used to input and display dates in a specific format, such as day/month/year or month/day/year. Date data can be used for tracking events, deadlines, or any other time-related information. Date data is typically right-aligned in a cell.

4. Formula: This data type is used to perform calculations based on other cell values. Formulas can be used to add, subtract, multiply, divide, or perform more complex calculations. Formulas are entered into a cell starting with an equal sign (=) and can reference other cells or ranges of cells. The result of a formula is displayed in the cell where the formula is entered.

1. Data cells contain the actual data values, such as text, numbers, dates, or times.
2. Formula cells contain formulas that calculate values based on the data in other cells.
3. Function cells contain functions that perform specific calculations, such as SUM, AVERAGE, or COUNT.
4. Empty cells do not contain any data or formulas.
