Excel spreadsheet
- 1. CHAPTER 2 SPREADSHEET A spreadsheet is a configuration of rows and columns. Rows are vertical vectors and columns are horizontal vectors. It is also known as worksheet .It is used to record, calculate and compare numerical or financial data
- 2. SPREAD SHEET Latest version - Microsoft excel 2007 Horizontal tabs –’Ribbon’ A file in excell is known as ‘work book’ A workbook is a collection of a number of ‘worksheets’ Default – three sheets(seet 1, 2,3) Active workssheet’s name will be shown in sheet tab in bold letters
- 3. SPREADSHEET Additional sheets can be inserted(insert botton at the bottom) Sheet rename option is available by right click Rows are numbered numerically from top to bottom(1-256)A-IV Columns are referred by alpha characters form left to right(65536 ) Total cells = 256* 65536 = 1,65,00,000
- 4. SPREAD SHEET • Intersection of row and column is called “Cell” • A cell is identified by a combination of letter and number corresponding to that cell(cell address) • Cell reference –A cell reference identifies the location of a cell or group of cells in the spreadsheet also referred as a cell address.
- 5. SPREADSHEET Mouse is used for navigation . Key strokes – Pressing a key is called key stroke To fulfill some command for operation some times we require pressing two keys together to get one key stroke.
- 6. SPREADSHEET MOVEMENT KEY STROKE ONE CELL DOWN DOWN ARROW KEY OR ENTER KEY ONE CELL UP UP ARROW KEY ONE CELL LEFT LEFT ARROW KEY ONE CELL RIGHT RIGHT ARROW KEY OR TAB KEY
- 7. SPREADSHEET MOVEMENT KEY STROKE TOP OF WORKSEET(CELL A1) CTRL+HOME LAST ROW AND COLUMN CONTAINING DATA CTRL+END BEGINNING OF THE ROW HOME KEY
- 8. SPREADSHEET • When data is entered in a cell in excel it is able to make out it’s type(ie, numeric or alpha numeric or date) • First decide about what values will be entered in which cells and the cellls which will be used for relationships
- 9. CALCULATING COMPUND INTEREST FOR FD • Define 6 cells with column headings TITLE Cell 1 Principal amount ( P A) B2 2 Rate of Interest (R) C2 3 Period in Years(NY) A2 4 Period of compounding(CP) D2 5 Compound interest(CI) F2 6. Maturity amount(MA) E2
- 10. Formula for compund interest and maturity amount • MA = PA*(1+R/(100*CP))^(R*CP) • CI = MA-PA
- 11. • BASIC TERMINOLOGIES IN SPREAD SHEET • Labels- a text or a special character will be treated as labels for rows or columns or descriptive information. Labels include any cell contents beginning with A- Z • Formula-Formula means a mathematical calculation on a set of cells. Formula must start with an = sign • The arithmetic operations and complex nested conditional (what –if scenario)operations can be performed by spreadsheets which follow order of mathematical(expression)operations rules
- 12. ORDER OF MATHEMATICAL OPERATIONS(EXPRESSIONS) • Computer math uses the rules of algebra • First operations contained in brackets • Then exponents • Division or multiplication operation to be of equal importance (carried out in the order they occur in the equation • Addition and subtraction .They are considered equal importance(carried out in the order they occur in the equation
- 13. Easy way to remember the order of operations using acronym GEMS ( ) Grouping ^ Exponents * Multiplication or: / Division - Subtraction: + or Addition
- 14. Easy way to remember the order of operations using acronym PEMDAS(Please Excuse My Dear Aunt Sally) ( ) Parenthesis ^ Exponents * Multiplication / Division + Addition - Subtraction
- 15. Easy way to remember the order of operations using acronym BEMDAS ( ) Brackets ^ Exponents * Multiplication / Division + Addition - Subtraction
