Example #1: the budget of expenses In this exercise we will download and edit an existing spreadsheet. The goal of this exercise is to get familiar working in the Microsoft Office 2010: Excel environment. This spreadsheet is a simple budget of household expenses. We will use the most common functions: Sum, Avg, Min, Max We will also write a custom formula while using some of the nifty built-in features of Excel. Finally, we will add a pie-chart based on our custom formula.

Formulas Tab Financial Logical Text Date & Time Lookup & Reference Math & Trig More We will only use a few of these for the next example

Date & Time Unless you are Kim Peak, you would need this to find days of the week in other years Great for setting work schedules Excel has trouble with dates before 1900 Networkdays: the number of standard work days between two dates Now: the time NOW! Date: gives the date in format eDate: gives the date in Excel serial format

Text Used for large blocks of text Same logical tests as computer programming Has functions to deal with funny formatting Concatenate Search Find Replace Substitute Dollar Value

Logical The series of logical mathematic tests If, Not, And, Or, True, IfError, False Very useful in creating statements that check for values Used in making an automatic grading structure And: true if both statements true Or: true if both statements are not false Not: reverses value If: checks for value and returns input value IfError: returns input if the statement errors True/False: returns that

Lookup & Reference Used to find data in large spreadsheets Has indexing and database options for organizing data, and useful attributes for Visual Basic coding Hyperlink: adds a hyperlink Transpose: takes a vertical array and transposes it horizontally GetPivotData: extracts from pivot table

Example #2: the Gradebook This exercise covers more of the formulas included in Excel. Here we will use formulas from Date & Time, Text, Lookup & Reference, and Logical. We will also use View tools to help examine the spreadsheet, and some formatting options to make it more visually appealing.
