Detailed explanation-1: -E$2 – In this reference, the dollar sign is right before the row number, and the Column notation has no dollar sign. This means that when you copy the formula down the cells, the reference will not change as the row number is locked.

Detailed explanation-2: -If you want to maintain the original cell reference when you copy it, you “lock” it by putting a dollar sign ($) before the cell and column references. For example, when you copy the formula =$A$2+$B$2 from C2 to D2, the formula stays exactly the same.

Detailed explanation-3: -Click the cell where you want to enter a reference to another cell. Type an equals (=) sign in the cell. Click the cell in the same worksheet you want to make a reference to, and the cell name is automatically entered after the equal sign. Press Enter to create the cell reference.

Detailed explanation-4: -A cell reference or cell address is a combination of a column letter and a row number that identifies a cell on a worksheet. For example, A1 refers to the cell at the intersection of column A and row 1; B2 refers to the second cell in column B, and so on.
