# Objective 2. Create a Formula in Excel

#### Activity 1.2. Creating a Formula for Calculation in Excel

Excel has many automatic functions for calculating, such as SUM. Sometimes you will need to perform a mathematical calculation without using one of these functions.

1.

Start Excel. From the folder that contains your project files, Open the Excel file Meeting_Data_Firstname_Lastname that you saved from the previous export activity.

Excel refers to columns by letters and rows by numbers. The intersection of a row and a columna cellis always named using the column letter first and then the row number, for example, A2. Clicking in a cell location enables you to enter or edit information in that cell.

2.

Click in cell B1, and then type Max to change the column heading. Press to complete the entry and move to cell C1. Click in cell C1, and then type Min to change the column heading. Press . Click in cell D1, and then type Difference as a new column heading. Press to complete the last cell entry.

You want Excel to calculate the difference between the Max and Min salary values. Excel formulas always begin with an = sign and use the cell reference (such as A2), not the actual value appearing in a cell.

3.

In cell D2, type the formula =B2-C2 Press . Cell D2 displays the calculated value.

You want to use the same calculation for the other items. The Auto Fill tool in Excel lets you duplicate the formula for the rest of the rows, using your difference calculation. The cell references will change relative to the new cell location for the formula, using the cells in the new row.

The Fill handle is a box at the lower right corner of a selected cell.

When the mouse pointer is on the Fill handle, it changes to a .

4.

In cell D2, click and drag the fill handle at the lower right corner of the cell to cell D6, and then release the mouse button.

This copies the formula to the other selected cells in the Difference column and changes the cell references for each rows calculation. The calculated value is displayed in each cell. Compare your screen with Figure 1.2.
