To see how this works, enter 10 in cell A1. Now, select cell A2 and type =A1*2, and then press
            ENTER key. The value in cell A2 is 20. If you change the value in cell A1 from 10 to any value, the
            value in cell A2 will also change.








                                        Using cell reference         After changing value
            Cell references are especially helpful when you create complex formulas. There are three types

            of cell references used in Excel: relative, absolute and mixed.
            Relative References


            In relative reference, you actually refer to cell that is above or below and left or right to a number
            of rows or columns. When a formula that possesses a relative reference is copied from one cell
            to another cell, the value in the copied cell also changes.

            To use the relative cell reference, perform the following steps:
            Step 1   Select the cell that contains the formula in which the reference of other cells is used. In

                     this case, we have selected the cell D3 which contains the =B3*C3 formula to calculate
                     the to amount to be paid for the product.

            Step 2  Click on the Copy command form the Clipboard group under the Home tab.
            Step 3   Select another cell in which you want to copy

                     the formula and click on the  Paste command
                     from the Clipboard group under the Home tab.
                     Notice, in the Formula bar that the cell address
                     that you have used in the formula gets changed

                     accordingly.
                                                                                  Using relative referencing
            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 by a Dollar ($) symbol.

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

            When you copy the formula to the next cell, address of the cell D3 will remain same as shown.
