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.
The key to formulas in Excel is cell references. Cell references tell Excel where to look to find the values it needs to calculate the result of a formula. Cell references can refer to one cell, a range of cells, or even entire columns and rows. Let's take a look. Every cell in an Excel worksheet has a unique address. The address of each cell is defined by it's location on the grid. The address B7 refers to the cell in the seventh row of column B, the address D6 refers to the cell in the sixth row of column D, and so on.
