Copy the Sum Function<br />
The Fill Handle is a useful tool to copy functions and formulas, such as Sum, into adjacent<br />
cells. Notice that in Figure 1-23 each day of the week contains the same number of figures to<br />
total. The formula to sum the numbers in the “Tuesday” column is the same as the formula to<br />
add the numbers in the “Monday” column except for the cell references. When you drag the<br />
Fill Handle, <strong>Excel</strong> automatically adjusts cell references. The formula automatically changes<br />
relative to its location on the worksheet.<br />
