Lesson Summary. This lesson discussed the different types of cell references in Excel. You learned that cell references can be relative, absolute or mixed. The type you use in a formula is important, as each behaves differently when copied or moved.
For example, when you enter or select the cell reference A2, the formula uses the value of that cell to calculate the result. You can also reference a range of cells. For more information about cell references, see Create or change a cell reference. Click the cell in which you want to enter the formula. In the formula bar, type = (equal sign). Do one of the following, select the cell that contains the value you want or type its cell reference.
