Applying Fundamental Excel Skills and Tools in Problem Solving Chapter 1 “When the only tool you own is a hammer, every problem begins to resemble a nail.” - Abraham Maslow
2.
Learning Objectives Level 1 Define common Excel error messages Correct basic formatting problems in a worksheet Correct errors in simple formulas Determine the order of precedence in formulas Understand precision versus display for cell values
3.
Learning Objectives Level 2 Work with multiple worksheets Calculate total, average, minimum, and maximum values with functions Understand how functions work: syntax, arguments, and algorithms Use the AutoSum feature to perform calculations quickly Calculate the number of values using both COUNT and COUNTA
4.
Learning Objectives Level 3 Organize a workbook Understand relative, absolute, and mixed cell referencing Write formulas with different types of cell referencing Copy formulas with different types of cell referencing Name a cell or cell range
5.
Functions Covered in This Chapter AVERAGE COUNT COUNTA MIN MAX SUM
6.
Chapter Introduction Fundamental skills and tools encountered when working with Excel to solve problems and support decision making Writing formulas in cells to perform calculations Designing a workbook so that calculations can be automatically updated if input values are changed Formatting options that can be applied to cells and ranges of cells Rules that affect how information is displayed and calculations are performed in an Excel worksheet
7.
Chapter Introduction (continued) Use of simple functions (i.e., shortcuts available for predefined tasks) Results of copying formulas with different kinds of cell references

Correcting Formatting Problems Modifying Column Width and Row Height Checking Error Messages (Error Alert button) Using Commas When Entering Values Formatting Numbers Formatting Dollar Values Inserting and Aligning a Title Inserting Columns and Rows Documenting a Worksheet = Best Practice
16.
Using Commas When Entering Values Commas in formulas can be problematic =SUM(2,235+B1) is interpreted as 2+235+B1 Rule of thumb: Don’t use commas but rather use styling if you want to display your numbers with commas
18.
In accounting, the preferred number format is to align values on the decimal point, in a column of dollars values, and to include a dollar sign only in the first entry in the column and for any grand totals. Repeated dollar sign can clutter the worksheet and are often unnecessary. Formatting Dollar Values
21.
Worksheet after Correcting Formatting Problems
22.
Documenting a Worksheet When working in teams, with several groups, or even with different companies, it is advisable to include a title on the worksheet, identify the creation date, worksheet author, and any specific information about the company, and/or project.
24.
Correcting Errors in Formulas Print the Worksheet in Two Different Formats Default format (displays values) Format that displays formulas Check Simple Formulas for Accuracy Use Formulas and Cell References Instead of Values Determine Order of Precedence Precision vs. Display Working with Dates (read on your own) Check Accuracy in Formula Updates
27.
Use Formulas and Cell References Instead of Values Notice cell D13 in the previous image Using cell references is preferable to directly inputting values into a formula. In this example, if the price of the leather changed or the quantity required to make a shoe increases, it would be easy to enter those changes. By using cell references in formulas the calculations will be automatically updated with any changes to that value.
29.
UnderstandingPrecision Versus Display Excel can display values in several different formats without changing the precise value stored in the program
32.
Level 1 Summary Locating and correcting common errors in formatting or formulas to make the worksheet readable and functional
33.
Level 2 Objectives:Calculating and Comparing Data Using Simple Functions Working with Multiple Worksheets Calculating Totals Using the SUM Function Understand how functions work: syntax, arguments, and algorithms Calculating Quickly with AutoSum Calculating Average, Minimum, and Maximum Values Inserting Rows and the Impact on Formulas (read on your own) Calculate the Number of Values Using the COUNT and COUNTA Functions
35.
Functions Functions are predefined formula that performs calculations Structure Function name and open parenthesis mark ‘(‘ Arguments (list of inputs in a specific order, separated by commas) Closing parenthesis mark ‘)’ Has its own syntax (specifies function name and order of arguments) Behaves according to its algorithm (rules programmed into the function)
36.
Calculating Totals Usingthe SUM Function SUM function Adds a list of values and/or cell ranges
37.
Calculating Quickly with AutoSum Excel has an AutoSum feature for quick calculation
39.
Calculating Average, Minimum, and Maximum Values The AVERAGE function ignores blank cells and cells with text.

Calculating Average, Minimum, and Maximum Values
41.

Level 3 Objectives:Analyzing Cell References When Writing and Copying Formulas Creating a Budget Workbook Organizing the Workbook Understanding Relative Cell Referencing Understanding Absolute and Mixed Cell Referencing Name a Cell or Cell Range Write Formulas with Different Types of Cell Referencing Completing the Budget Wordbook
44.
Creating a Budget Workbook Setting up a preliminary budget
45.
Organizing the Workbook Inputs and outputs on separate worksheets One worksheet for each quarter with all inputs and outputs for all three pricing alternatives on a single worksheet One worksheet for each pricing alternative with all inputs and outputs for all four quarters on a single worksheet
46.
Understanding Relative Cell Referencing Allows use of a “general” formula over and over again, but with a different set of numbers Can also copy formulas using the fill handle
47.
Relative Cell Referencing Excel automatically alters the new formula relative to the location of the original formula
48.
Understanding Absolute and Mixed Cell Referencing Absolute cell referencing To indicate that a cell reference (both column and row) – or even a part of a cell reference – should remain unchanged when copying Syntax = $ before column letter, before reference number, or both Mixed cell referencing A cell reference that has only one $ Common when you need to copy a formula both down a column and across a row at the same time
49.
Understanding Absolute and Mixed Cell Referencing The formula entered in cell C11 applies absolute and mixed cell referencing
