3. What are spreadsheets? A spreadsheet is an interactive computer application program for organization, analysis and storage of data in tabular form. Spreadsheets developed as computerized simulations of paper accounting worksheets. The program operates on data represented as cells of an array, organized in rows and columns. Each cell of the array is a model–view–controller element that can contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. Panayiotis Christodoulou

4. The user of the spreadsheet can make changes in any stored value and observe the effects on calculated values. Spreadsheets have replaced paper-based systems throughout the business world. Although they were first developed for accounting or bookkeeping tasks, they now are used extensively in any context where tabular lists are built, sorted and shared. Panayiotis Christodoulou

5. What is Excel? Microsoft Excel is a spreadsheet application developed by Microsoft for Microsoft Windows and Mac OS. It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications Panayiotis Christodoulou

37. Cell ranges A group of cells is called a cell range or range An adjacent range is a single rectangular block of cells A nonadjacent range consists of two or more distinct adjacent ranges A range reference indicates the location and size of a cell range Panayiotis Christodoulou

38. Select adjacent range Just click on a cell and is selected To select more than one cells first select one and then drag your mouse to select more or using the Shift + arrows Panayiotis Christodoulou

39. Select nonadjacent range Select a cell or an adjacent range and then using the Ctrl button select more cells Panayiotis Christodoulou

40. Select all cells Click Ctrl + A Or the Select all button Panayiotis Christodoulou

45. Formulas A formula is an expression which calculates the value of a cell. Functions are predefined formulas and are already available in Excel. The order of precedence is a set of predefined rules used to determine the sequence in which operators are applied in a calculation Panayiotis Christodoulou

46. Order of Precedence Panayiotis Christodoulou

47. Entering a formula First click the cell you want the formula results to be appear Type = and then the expression which described the formula Press Enter Panayiotis Christodoulou

48. Functions You can type in a formula (though you have to be sure it's exactly right) or you can use Excel's preset formulas called functions. If you type in the formula, you must start with an equal sign, so Excel knows that the data in the cell is a formula. Panayiotis Christodoulou

49. Add Numbers A1 = 30 A2 = 40 To find the sum in A3 we must write: A3 = A1 + A2 Panayiotis Christodoulou

50. Add more than two numbers A1 = 3A4 = 6 A2 = 4A5 = 7 A3 = 5A6 = 8 To find the sum in A7 instead of writing = A1 + A2 + ….. is better to use the function = Sum(A1:A6) Panayiotis Christodoulou

52. Average Function To find the average value of a row or a column Panayiotis Christodoulou

53. Other Math Formulas/Functions FormulaSign Subtract= A1-A2 Multiply= A1*A2 or PRODUCT(A1:A2) Divide= A1/A2 Absolute Value= ABS(A1) Round up= ROUNDUP(A1,0) Round down= ROUNDDOWN(A1,0) Raise to power= POWER(A1;2) Min value= MIN(A1:A6) Max value= MAX(A1:A6) Panayiotis Christodoulou
