9. Introduction to Excel

10. 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,…

11. 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

12. 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  19yy =Date(2012,9,14) Time: Min:Sec 15:25 Date and time: mm/dd/yy min:sec Text Home/Fill/Series

13. 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

14. Cell Reference

15. Demo Note: Software consists of three parts: INPUT, PROCESS, OUTPUT.

16. Copy Formula Drag the source cell Copy/Paste

17. 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

18. AnnualGrowthRate: 5% of the previous year. Compute the forecasted sales for the next 5 years

20. Mixed Cell Reference $ColumnRow: $A1 Column$Row: A$1 Examples: =$A1 =A$1

21. Cases Where Mixed Cell Reference are Optional

22. Case that Must Use Mixed Cell Reference
