Using Excel 2010

OVERVIEW

• Complex Formulas• Basic Functions• Arrays• Sorting Data• Outlining Data• Filtering Data• Formatting Tables

COMPLEX FORMULAS

• A complex formula involves more than one mathematical operation

• Calculations are done according to the Excel’s order of operations

Order of Operations

• Calculate the percentage of sales of Pete Lily seeds sold that were of the white variety

Complex Formula by Cell Reference

• Calculate the total order amount due for this order

Create & Copy FormulaRelative References

Formulas with Absolute References

• You can use an absolute reference to keep a row and/or column constant in the formula.

Absolute References

• Calculate the tax amount due on each item in this customer's order

Absolute References

BASIC FUNCTIONS

• Excel has an entire library of functions or predefined formulas that users can take advantage of

• common functions include sum, average, product or count,

• Excel has hundreds of different functions to assist with your calculations, including things like formatting text, referencing cells, calculating financial rates, analyzing statistics

Function Library

• A great place to explore functions is in the Function Library on the Formulas tab.

• Excel functions categories include Financial, Logical, Text, Date & Time

• Let us review some of them

Function Library

Insert Function Command

• The Insert Function command enables users to search for a function by typing a description or by selecting a category to peruse

OUTLINING DATA

• Outlines give the ability to group data that you may want to show or hide from view, and create a quick summary using the Subtotal command.

• Always sort before outlining.
