FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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. This is an absolute reference.

Detailed explanation-2: -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-3: -Press F2 (or double-click the cell) to enter the editing mode. Select the formula in the cell using the mouse, and press Ctrl + C to copy it. Select the destination cell, and press Ctl+V. This will paste the formula exactly, without changing the cell references, because the formula was copied as text.

Detailed explanation-4: -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-5: -If you want to maintain the original cell reference in this example when you copy it, you make the cell reference absolute by preceding the columns (B and C) and row (2) with a dollar sign ($). Then, when you copy the formula =$B$4*$C$4 from D4 to D5, the formula stays exactly the same.
