1. Practical 1: Using MS Excel for financial computation Gopalan Vivek vivek@bic.nus.edu.sg

2. Objectives Identify major components of Excel window Navigate within and between worksheets Select and move worksheet cells Insert text, date and values Insert and delete worksheet row and columns Resize worksheet rows and columns Print a worksheet

3. Start using MS Excel Open a blank Excel windows Open an existing Excel file Terms ( What is ?) Workbook (Excel file) Worksheet or spread sheet (sheets in the file) Cell Cell Range

4. Start using MS Excel

5. CELL Cell is the fundamental unit of excel worksheet. Constant values (string,number) Formulae (sum, average) Logical (TRUE,FALSE) Date(02/08/2003) Format Manipulate color, background, border, protection, size, font, type. Format->cell formatting cell Click in the menu Format->cell or right on a cell and click on formatting cell for more details in formatting the cell

6. Entering information into cell Enter text – phone number and Matric No.s are treated as text, text is aligned left by default – “finance”,”A1250” Enter constant values, value is aligned right by default – 1, 25, 0.05 etc. Enter date – “8/28/2002”, “28-Aug- 2002”, “August 28, 2002”

7. Handling Cell content Deleting 1.Select the cell Del 2.Delete the content using the ‘ Del ‘ key or type on the cell to overwrite it. Editing F2 –‘Double click’ on a cell or select the cell and press ‘F2’ function key. To cancel any changes, press ESC.

8. Cell address ‘A1’ is the reference to cell content in column A and row 1.

9. Working with cell range Cell range-- adjacent range and nonadjacent range To refer to a range of cells, enter the reference for the cell in the upper-left corner of the range, a colon (:), and then the reference to the cell in the lower-right corner of the range A3:B4 – adjacent range A1:C4;A7:C11 - non adjacent range F5 Use function key ‘F5’ to navigate around the worksheet

10. Formula A formula is an equation that performs operations on worksheet data. (SIN(0.25),2*2, etc ) Perform mathematical operations, such as addition and multiplication Compare worksheet values or join text. Refer to other cells on the same worksheet, cells on other sheets in the same workbook, or cells on sheets in other workbooks. Entering a formula 1.Click the cell in which you want to enter the formula. 2.Type = (an equal sign). Enter the formula. 3.Press ENTER.

11. Examples: =(5+2)*3 =A1*SIN(PI()/4)

12. Move or copy a formula When you MOVE a formula, the cell references within the formula do not change. When you COPY a formula, absolute cell references do not change; relative cell references will change. (See the next 2 slides for more details)

13. Relative Referencing A cell reference used in a formula changes when the formula is COPIED to another cell or range. –After the formula is copied and pasted, the relative reference in the new formula is changed to refer to a different cell that is the same number of rows and columns away from the formula as the original relative cell reference is to the original formula. For example, if cell A3 contains the formula =A1+A2 and you copy cell A3 to cell B3, the formula in cell B3 becomes =B1+B2. Relative Referencing

14. Absolute referencing Unlike relative references, absolute references don't automatically adjust when you copy formulas across rows and down columns. –Use the ‘$’ character before the column or row references to ‘FREEZE’. –It takes the form $A$1, $B$1, and so on. –An absolute row reference takes the form A$1, B$1 and so on.(Row reference won’t change when copying the formula) –An absolute column reference takes the form $A1, $B1, and so on..(Column reference won’t change when copying the formula) F4 Type a formula in cell and press function key ‘F4’ several times to change the FREEZE status.

15. Mouse Pointers

16. Working with rows and columns Insert or delete a row or column Insert or delete multiple rows or columns Insert or delete individual cells shift cell left, shift cells down, entire row, entire column Resize the width of the row or height of the column insert rowdelete row Type “insert row” or “delete row” in the Excel Help to learn more about insertiing and deleting cells. Press function key ‘F1’ for help.

17. Select a range Select a adjacent range Select a nonadjacent range Select all the cell in the worksheet Select a large amount a cell Select a entire row or column select text Type “select text” in the Excel Help to learn more about selection features. Press function key ‘F1’ for help.

18. Exit the Excel Remember to save before exit the application

19. Income statement Text & constant value editing Formatting –Cell border –Cell font, background color –Cell size –Cell format (number of decimal character,etc.) Formula Referencing

23. Practice – Do this after finishing your Quiz (if you have time) 1. Create a multiplication table (30 x 30) using formula. 2. Find the average, sum, minimum, maximum values of the function y = 10 x 3 + 5 x 2 for x = 0, 0.1, 0.2, …, 20.
