We will be using Microsoft Excel Excel files end with the extension:.xlsx 5 6 1

2 a Spreadsheet is composed of columns and rows Specifications (Excel 01) Max number of rows: 1... A B C D ,048,576 Max number of columns: 16, Rows This is a ROW in Excel Columns This is a column in Excel 9 10 Cells This is a cell in Excel Cells Every cell is identified by column-row coordinates Every cell is identified by column-row coordinates ,048,576 A B C D ,84 B Cell B B = Column = Row 11 1

3 How can we enter data? Activate the cell that we will enter the data. How? Data Entering Enter the data (letters and numbers) like in word-processing (type-in) (use backspace to erase the errors) Move the mouse cursor to the cell that you want to activate and click it. (The cell now has a thick square around it) (Use the arrow keys to move around to activate other cells) 1 14 Note Formula bar As you type-in the data, the numbers and letters will appear in the activated cell and also in the FORMULA BAR Formula Bar Cell width Maximum width = 55 If you see signs (###) in a cell, it means that the cell is not wide enough to display the values entered in it.. change the size of width. Change the cell width Go to Home tab; Cells group Format Column width Replace the number in the small window with your choice (0-55) O.K 17 18

4 Change the cell width Change the cell width 19 0 Which arithmetic operations are in Excel? In Excel we can do Exponentiation ^ Multiplication * Division / Addition + Subtraction - (caret) 1 How can we perform calculations? Begin with the equal sign: = In EXCEL all mathematical operations must begin with the equal sign = 4 4

5 Simple calculations Must begin with the equal sign = Example: + = (+)/5 (Excel) 5 Another example Must begin with the equal sign = Example: + = (+)/5 (Excel) 5 5 = 5*(/) (Excel) 5 6 Rules of precedence Multiplication and division done before addition and subtraction Rules of precedence Multiplication and division done before addition and subtraction Calculations within parenthesis done first. 7 8 Rules of precedence Multiplication and division done before addition and subtraction Calculations within parenthesis done first. Exponentiations done before all other operations, except those enclosed in parentheses. Summary ( ) Parenthesis (first) ^ Exponential (second) * Multiplication (third) / Division (third) + Addition (fourth) - Subtraction (fourth) = Equal (fifth) 9 0 5

6 Example - Rules of precedence + 6/ = 9/ = Example - Rules of precedence + 6/ = 9/ = (Wrong) + 6/ = + = 5 (Correct) First: division Then: addition 1 Example - Rules of precedence + 6* =? Example - Rules of precedence + 6* = 9* = 7 (Wrong) + 6* = + 18 = 1 (Correct) First: mult Then: addition 4 Can we align the contents of a cell? Can we align the contents of a cell? Yes Highlight(select) the columns or rows that you will like to align a certain way. Then, under the Home tab and in the Alignment group > Left > Top > Right > Middle > Center > Bottom 5 6 6

7 Can we align the contents of a cell? Yes To insert rows or columns Highlight(select) the columns or rows that you will like to align a certain way. Then, under the Home tab and in the Alignment group Click on the row or column that you wish to insert a new row or column. Go to the Home tab; Cells group Click down-arrow next to Insert Select [Rows/Columns] to be inserted > Left > Top > Right > Middle > Center > Bottom 7 8 Delete columns/rows Change text orientation Highlight the row or column that you wish to delete Go to the Home tab; Cells group Click down-arrow, next to Delete Select [Rows/Columns] to be deleted On the Home tab; Alignment group click on 9 40 Change text orientation Merge and Center Under the Home tab, click the dialog box launcher to the right of Alignment, in the alignment group, and then in the Orientation box, click a degree point, or drag the indicator to the angle you want. The dialog box launcher, to the right of Alignment in the Alignment group Orient.xls
