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 Formula Relative 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

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

Parts of a Function

Create a Basic Function

Using Autosum

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

Insert Function Command

Functions - Financial Ex: Future sum from annual payments

Functions – Math & Trig

Functions - Statistics

Functions - Text

Functions - Logical

Functions - Information

Functions – Lookup & Reference

Other Functions - Engineering Students, find examples on your own for – Engineering – Cube Tip: When working with some function in your other course work, look it up in Excel. It may save you a chunk of time and effort

MATRICES An array is multidimensional list of elements A vector is an array with one row or one column A matrix has at least two rows or two columns In Excel, matrix elements can be entered directly into cells

Matrix Addition

Scalar Multiplication You may type F4 to get the Absolute Reference

Transpose of a matrix

Hit F2

Hit Ctrl-Shift-Enter

Transpose of Matrix (Alternate)

Matrix Multiplication

Hit F2 Ctrl-Shift-Enter

Determinant of a Matrix

Inverse of a Matrix F2

Inverse of Matrix Ctrl-Shift-Enter

Systems of Linear Equations

SORTING DATA Arranging your data alphabetically, from smallest to largest, etc, can help you find the information more quickly.

Sorting Alphabetically

Sorting in Numerical Order

Sorting By Date and Time

Custom Sort

Sort By Cell Color, Font Color Etc

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.

Outline Data Using Subtotal This sales data has been sorted by T-shirt size

Outline Data Using Subtotal

Show/ Hide Outlined Data

View Outlined Data by Group Level
