EXCEL NESTED FUNCTIONS – HOMEWORK – Due – Tuesday, December 6, 2011
Objective: Students will be able to explore, utilize and produce Excel “nested” functions to
calculate data.
A nested function in Excel refers to one or more function being placed inside another. This is done to
extend the capabilities of a function. How it works is that the nested functions are used as arguments
of the first function. See example below.
Figure 1.
Excel's ROUND and SUM Functions
The steps that will be followed in this example are:


Add together the data in cells D1 to D3 using the SUM function
Round off the above answer to 2 decimal places using the ROUND function
The use and syntax for each function is:
The SUM function provides a quick way to add numbers together in an Excel spreadsheet.
The syntax for the SUM function is:
=SUM ( Number1, Number2, ... Number255 )
Up to 255 numbers can be entered into the function.
The ROUND function is used when rounding integers and decimal numbers to make them easier to
work with in a spreadsheet.
The syntax for the ROUND function is:
=ROUND( Number, Num_digits )
Number = the number to be rounded - it can also be a formula, another function, or a cell reference to
a number or formula.
Num_digits = the number of digits or the number of decimal places that the number is to be rounded
to.
In the example below, the SUM function will be used as the Number argument in the ROUND function.
Example: Nesting Functions in Excel
For help with this example, see the image above.
1.
Enter the following data into cells D1 to D3: 4.351, 5.824, 9.17.
2.
Click on cell D4, the cell where the functions' result will be displayed.
3.
Click on the Formulas tab.
4.
Click on the Math & Trig option on the ribbon to open the Function drop down list.
5.
Scroll down through the list and click on the ROUND option to bring up the Function
Arguments dialog box.
6.
7.
Click on the Number line in the dialog box.
Type sum (d1 : d3) to enter the SUM function as the Number argument of the ROUND
function.
8.
Click on the Num_digits line in the dialog box.
9.
Type a 2 in this line in order to round the answer to the SUM function to 2 decimal places.
10.
Click OK.
11.
The answer 19.35 should appear in cell E1 since we have rounded off the sum of the data in
cells D1 to D3 (19.345) to 2 decimal places.
12.
Click on cell E1 and you should see the nested function
= ROUND(SUM (D1 : D3), 2) in the formula bar.
YOUR ASSIGNMENT: Create a nested function for your CTE Wireless LLC
Project based on the example in this sheet. Also, refer to the links and PowerPoint
slideshow that I have provided for you at www.quia.com. This assignment is very
important, it will help you complete your project faster and more accurately. Study
it carefully.
To receive an ‘A’ or 100 points for your homework assignment, you must be have
a formula already created when you arrive on Tuesday, December 6th. NO
