Arithmetic Operators
• +, -, *, /, ^, ( )
• Evaluating an expression– Examples:
• 4 + 2 – 1• 4 + 2 * 3• 3 – 4 / 2• 8 / 4 * 2• 2 * 3 ^ 2• (2 * 3) + 2 ^ 3
Order of Evaluation
• Operator Multiples
• 1 ( ) Inner to outer, left to right
• 2. ^ left to right

Expression to Formula
• A / B * C - 2
• A + B * C ^ D
• (A + B / (C – 2)) ^ D + 1
• Evaluating an expression:• 4 * 2 + 8 / 4 * 2 ^ 2 – 1• 18 / 3 ^ 2 * (1 + 2)
Introduction to Excel
What is a spreadsheet?
• It is a matrix composed of rows and columns. Columns are identified by letters and rows are identified by numbers.– Columns: A – Z, AA – AZ, BA – Bz,…
Cell & Range
• Cell: Intersection of row and column identified by specifying column and row coordinates.– A1, B3
• Range: A group of rectangular shape cells identified by specifying the upper left corner and the lower right corner.– B2:D3, A1:A3
Enter Constant in a Cell• Number:
– 2.345, -1000, (1000)– With comma or $: 1,234, $1,234.56– Fraction: 1 7/9, 1/3– Percentage: 5.25%
• Date: mm/dd/yy (without “=“)• If yy < 30 20yy. If yy>=30 19yy• =Date(2012,9,14)
• Time: Min:Sec• 15:25
• Date and time: mm/dd/yy min:sec• Text• Home/Fill/Series
Enter Formula and Function in a Cell
• Formula:– Begin with an “=“– Use operators: +, - , *, /, ^, ( ) to define a formula.
• Function:– =SUM(A1:A3)
• Formula with function:– =SUM(A1:A3) * 5 + B5/2
• To display formulas:– Formulas/Show Formulas
Cell Reference
Demo
Note: Software consists of three parts: INPUT, PROCESS, OUTPUT.
Copy Formula
• Drag the source cell
• Copy/Paste
Cell Reference
• Relative cell reference: After copy, the formula will reference cells with the same relative position as the original formula.– Example:
• Value in cell E6: C6*D6
• Absolute Cell Reference: After copy, the formula still references the same cell as the original formula.– Example:
• Tax in cell F6: E6*$C$3
AnnualGrowthRate: 5% of the previous year. Compute the forecasted sales for
the next 5 years
Mixed Cell Reference
• $ColumnRow: $A1
• Column$Row: A$1
• Examples:• =$A1• =A$1
Cases Where Mixed Cell Reference are Optional
Case that Must Use Mixed Cell Reference
