Absolute References

                  If you wish to maintain the original references as they were, then you should make use of the absolute
                  references. If you want to make the formula retain the original reference when it is copied, then you
                  should precede the column reference and the row reference with a dollar ($) symbol.

                  For example, if you want to give a discount of 10% on each product, then the discount will remain the
                  same for all the products. To calculate the amount to be paid, you should add the dollar ($) sign to
                  the cell that contains the discount percentage. In this case, the discount percentage is given in cell
                  D3. Hence, the formula will be =((B3*C3)-((B3*C3)*($D$3))).
                  When you copy the formula to the next cell, the address of the cell D3 will remain the same as shown:






















                  Mixed References

                  A mixed reference is a reference that refers to a specific row or column. It is basically a combination
                  of relative and absolute references. In some situations, you may need to make the cell reference as a
                  ‘Mixed’ reference so that you can lock either a column or a row by preceding it with a Dollar ($) symbol.
                  For example, $A1 or A$1.

                                                                 Notes

                                   Pressing the F4 key repeatedly over a reference cell name in the
                                    formula allows you to make the reference a relative reference,
                                  absolute reference or mixed reference by switching between them.


                  References to Other Worksheets

                  You can refer to cells in other worksheets within the same workbook just as easily as you refer to
                  cells in the same worksheet.

                  For example, to enter a reference of cell A2 in Sheet2 into cell A1 in Sheet1, follow the given steps:
                   Step 1   Select cell A1 in Sheet1, and type an equal (=) sign.
                   Step 2   Click the Sheet2 tab.

                   Step 3    Click cell A2, and then press the Enter key. When you press the Enter key, Sheet1 is now
                            active.
                   Step 4   Select cell A1, and you will see that it contains the formula = Sheet2!A2.
