Cell references in spreadsheets indicate the value of other cells and can be in different styles: relative, absolute, and mixed. Relative references adjust when formulas are copied, while absolute references remain constant. Mixed references can be column or row absolute, and the F4 key can toggle these reference types.

1. Cell References
A cell reference refers to the value of a different cell or cell range on the current worksheet
or a different worksheet within the workbook.
Cell references come mainly in two styles. But, depending on the use of the dollar sign
symbol, the number of styles can be increased to four.
1. Relative:
Example: A1. Cell reference adjusts to new location while copying formula
2. Absolute:
Example: $A$1. There is no change in cell reference while copying formula

2. 3. Mixed: Row Absolute
Example: A$1. Column is changing, row doesn’t change while copying formula
4. Mixed: Column Absolute
Example: $A1. Column doesn’t change, row is changing while copying formula
Hint: Pressing F4 Key the status of cell references can be changed
