For example, a formula (=A2*B2) placed in cell C2 multiplies the values of cells A2 and B2. As we
                 press the Enter key, the result of the multiplication of values in A2 and B2 is displayed in cell C2.

                 If we copy the formula (=A2*B2) in cell C3, then the cell references in the formula (=A2*B2) change
                 in relation to the new location of the formula, and the result is displayed according to the changed
                 cell reference.

                                                                                             the formula in cell C3,
                                                                                               cell references are

                                     Result of formula

                 ABSOLUTE CELL REFERENCING                                    Typing the formula (=$A$2 + $B$2)

                 In  absolute cell referencing, cell references in the        in cell C2 for absolute referencing
                 formula remain the same even if we copy and paste the
                 formula to a new location. It is used when you maintain
                 the original references as they were. For this, we need
                 to use the $ (dollar) sign as a prefix before the column
                 name and row number in the formulas.

                 For example, if we want the value of A1 to be  constant
                 when multiplying it with a cell from column B, absolute
                 referencing will be used.

                 When the formula (=$A$2*$B$2) in cell C1 is copied            Displaying constant result after copying
                 and pasted to C2, the values in cells A2 and B2 remain            and pasting formula in cell C3
                 unchanged.


                 MIXED CELL REFERENCING

                 A  mixed cell reference refers  to  a specific  row  or
                 column. It is basically a combination of relative and
                 absolute references. There are times when we may
                 want a part of the cell reference to change when the
                 formula is copied.

                 In some  situations,  you  may  need  to  use  a  ‘Mixed’
                 reference, so that  you  can lock either  a column or
                 a row by preceding it with a Dollar ($) symbol. For
                 example,  when the column letter  changes, the row                            Typing the formula using
                 stays constant or vice versa.                                                  a mixed cell reference
