Detailed explanation-1: -There are two types of cell references: relative and absolute. Relative and absolute references behave differently when copied and filled to other cells. Relative references change when a formula is copied to another cell. Absolute references, on the other hand, remain constant no matter where they are copied.

Detailed explanation-2: -What Is An Absolute Reference? In Excel, an absolute reference is a cell reference in which the column and row coordinates stay constant while copying a formula from one cell to the other. A dollar symbol ($) is used before the coordinates to correct them. For instance, $D$2 is an absolute reference to cell D2.

Detailed explanation-3: -By default, a cell reference is a relative reference, which means that the reference is relative to the location of the cell. If, for example, you refer to cell A2 from cell C2, you are actually referring to a cell that is two columns to the left (C minus A)-in the same row (2).

Detailed explanation-4: -If you do not want cell references to change when you copy a formula, then make those cell references absolute cell references. Place a “$” before the column letter if you want that to always stay the same. Place a “$” before a row number if you want that to always stay the same.
