2. Functions S S T : S P R E A D S H E E T S SST 5 Objectives 1.Use functions like Sum and Average 2.Use a shortcut to compute the total for columns and rows

3. Functions S S T : S P R E A D S H E E T S SST 5 3.1 Introduction Spreadsheet allows you to enter formulae to perform calculations efficiently A ‘function’ is a built-in formula that comes with a spreadsheet program It is used in place of a long formula

4. Functions S S T : S P R E A D S H E E T S SST 5 3.1 Introduction

5. Functions S S T : S P R E A D S H E E T S SST 5 3.1 Introduction The Sum function In cell B10, instead of using the long formula “=B3+B4+B5+B6+B7+B8+B9” to add up cells B3 to B9, a function “=SUM(B3:B9)” is used The range B3:B9 indicates the cells to be summed up

6. Functions S S T : S P R E A D S H E E T S SST 5 3.1 Introduction The Average function In cell B8, instead of using the formula “=(B4+B5+B6)/3” to average up cells B4 to B6, a function “=AVERAGE(B4:B6)” is used

7. Functions S S T : S P R E A D S H E E T S SST 5 3.1 Introduction The Maximum and Minimum function The Maximum function returns the maximum value from a range of cells specified The maximum value in cells B4 to B10 is 60 and the Maximum function will find it

8. Functions S S T : S P R E A D S H E E T S SST 5 3.1 Introduction The Maximum and Minimum function (Cont’d) The Minimum function returns the minimum value from a range of cells specified The minimum value in cells B4 to B10 is 29 and the Minimum function will return this value

10. Functions S S T : S P R E A D S H E E T S SST 5 3.2 Copying Cell Contents You can copy cells by click-and-drag

11. Functions S S T : S P R E A D S H E E T S SST 5 3.2 Copying Cell Contents To copy using click-and-drag Move the cursor pointer to the bottom-right corner of the cell to be copied When the mouse pointer changes to a plus sign, right click and drag to select the range that you want to copy to Release the mouse button at the end The cell content will be copied to the selected range

12. Functions S S T : S P R E A D S H E E T S SST 5 3.2 Copying Cell Contents 1.= SUM(B1:B3) or = B1 + B2 + B3 2.= SUM(C1:C3) or = C1 + C2 + C3

13. Functions S S T : S P R E A D S H E E T S SST 5 Summary 1.A function is a built-in formula that comes with a spreadsheet program. It is used in place of long formulae. 2.The Sum function is used to find the total of the values in a range. 3.The Average function is used to find the average of the values in a range.

14. Functions S S T : S P R E A D S H E E T S SST 5 Summary 4.We can use the click and drag method to copy cell contents.
