In this lesson, you will learn how to create simple formulas in Excel to add, subtract, multiply, and divide values in a workbook. You'll also learn the various ways you can use cell references to make working with formulas easier and more efficient. Simple formulas A formula is an equation that performs a calculation. Like a calculator, Excel can execute formulas that add, subtract, multiply, and divide.

Like a calculator, Excel can execute formulas that add, subtract, multiply, and divide. This is called using a cell reference. To maximize the capabilities of Excel, it is important to understand how to create simple formulas and use cell references.

You can download this example for extra practice. This is because the cell contains—or is equal to—the formula and its value. To create a simple formula in Excel: Select the cell where the answer will appear B4, for example. Entering formula in B4 Press Enter. The formula will be calculated, and the value will be displayed in the cell.

Result in B4 If the result of a formula is too large to be displayed in a cell, it may appear as pound signs instead of a value.

This means the column is not wide enough to display the cell content. Simply increase the column width to show the cell content. Creating formulas with cell references When a formula contains a cell address, it is called a cell reference. Creating a formula with cell references is useful because you can update data in your worksheet without having to rewrite the values in the formula.

To create a formula using cell references: Select the cell where the answer will appear B3, for example. Selecting cell B3 Type the cell address that contains the first number in the equation B1, for example.

Entering a formula in B3 Type the operator you need for your formula. Type the cell address that contains the second number in the equation B2, for example. Entering a formula in B3 Press Enter.

Result in B3 If you change a value in either B1 or B2, the total will automatically recalculate. To create a formula using the point-and-click method: Selecting cell B4 Click the first cell to be included in the formula A3, for example.With a Weighted Average, one or more numbers is given a greater significance, or weight.

Find a Weighted Average. Use the SUMPRODUCT and the SUM functions to find a Weighted Average, which depends on the weight applied to the values. For example, a shipment of 10 cases of pencils is . In cell A7, enter a AVERAGEA formula, to average the numbers in column A: =AVERAGEA(A1:A5) Press the Enter key, to complete the formula.

The result will be , the average of the cells that contain data. Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site.

Writing Excel Formulas: Keep it Simple. If you need to write a formula for a complex calculation, break it into small steps. There is no rule that says the result has to be calculated in one step so, if you have to, create columns for each intermediate step in the complex calculation.

8. Now you can use this function just like any other Excel function to calculate the average of numbers that fall between two values. Result: As a check, you can delete all values that are lower than 10 and higher than 30 and use the standard Average function in Excel to see if Excel calculates the same average as our custom average function.
