Spreadsheet: Electronic sheet of paper
organized by columns & rows
The advantage of an electronic spreadsheet is it
allows you to easily change data and have all
“related” calculations automatically update..
CS&E 1111 Excel Intro
Spreadsheets in Excel are referred to as worksheets.
A workbook file may contain may worksheets.

Cell D2
Contains
the Formula
= B2*C2
Each box is referred to as a “cell”. Cells may contain
Labels, Values or Formulas that result in a value or
label. A cell is identified first by its column letter and
then by its row number
Labels
CS&E 1111 Excel Intro
One can also write formulas that refer to
cells on other worksheets –
Sheetname!Cell-Reference
input!B1*input!B3 + A1
When referencing a cell
on the same
spreadsheet as the
active cell the sheet
name is not required.
Sheets may be named and displayed with different colors tabs,
The order of the worksheets may be modified as well.
CS&E 1111 Excel Intro
File tab – opens menus for opening and
saving Files, and modifying Excel Options
Quick Access Toolbar can be
customized to include icons to frequently
Used features such as Print Preview
Home Ribbon use to change fonts, justify text, insert
rows etc. Ribbons are organized into Groups of similar tasks
such as the Font group or the Number group. In addition, there
are other ribbons containing groups/buttons for laying out pages
using the review features etc.

 Each entry can be related to other values by
including cell referencing in formulas.
 Formula values are automatically updated
when a referenced value changes
 Formulas can be copied
 Charts can be easily generated
The “Power” of using Spreadsheet Applications
=B2*C2
CS&E 1111 Excel Intro
Formulas
 A formula is a sequence of values, cell
references and operators that produce a new
value.
= E8 + 3*(E10 - E11)
 Formulas always start with an equal sign =
 In addition a formula can also contain built-
in functions like SUM, AVERAGE, IF,
COUNTIF, etc. =Sum(A2:A8)*2
CS&E 1111 Excel Intro
Things you need to know when writing
formulas in Excel
 Data precision vs. cell
display
 Types of operators that can
be used
 Order of precedence of
operators
/ ≤ −
=B2+B3*B1/B8^2
CS&E 1111 Excel Intro
In order to write Excel formulas we also
need to use the correct Operator Symbols
Formulas contain two types of components:
 Operators: Operations to be performed
Arithmetic operators: * / + - ^
Relational operators: >, <, <=, >=,< >,=
 Operands: Values to be operated on
= B2 + 5
Operands
Addition
Operator
CS&E 1111 Excel Intro
Precedence of Operators
 ( ) Parenthesis is a special operator that forces
evaluation of the expression inside it first
 Exponentiation (2^3 8)
 Arithmetic operators: Multiplication & Division
 Multiplication & Division have equal precedence and
are evaluated from left to right
 Arithmetic operators: Addition & Subtraction
 Addition & Subtraction have equal precedence and are
evaluated from left to right
 Relational operators have a lower precedence than
arithmetic operators
CS&E 1111 Excel Intro
Type in a cell : =1/8
display in cell
What value results for
each - if multiplied by
1000?
Does the addition appear
to be correct in col B?
Precision: number of decimal places stored in the
computer.
Formatted Display: number of decimal places that
appear in a cell
CS&E 1111 Excel Intro
Formatting affects display not the
precise value:
Percent Decimal Display
Currency Commas
Formatting
Number Group
CS&E 1111 Excel Intro
Values can also be used to display dates
 Dates are values that can be
entered in several formats:
January 27, 2013 or 1/27/2013
 Excel converts these dates to a
numerical representation
(1/22/2013  41301)
 Thus dates may be used in
formulas: =A1–B1 will result in
the value 5
Note: To do arithmetic calculations with dates if you type =1/27/2013-
1/22/2013 directly in a cell it does not interpret it a date – cell references
must be used.
