Absolute Reference
This is the position of a cell that when a formula using it is copied will always refer to that cell.
To make an absolute reference to a cell use the $ symbol before the row or column name.
For example when copied:
- $B$4 will always reference cell B4
- B4 will change whenever it is copied. If you copy one row down and one column across the B will change to a C and 4 will change to a 5
- $B4 will only change the row. If you copy one row down and one column across the B will stay as B and 4 will change to a 5
- B$4 will only change the row. If you copy one row down and one column across the B will change to a C and 4 will stay as a 4
