# Functions

They can apply to an individual cell or to a range of cells, on the same spreadsheet,
or on another worksheet in the same workbook,
or on another worksheet in another workbook.
##### Excel formulas: The most popular functions and tools, with examples
• Formula
• A formula starts with =, and is followed by mathematical operators and cell addresses
• For example:
• =D4+D5+D6+D7
means
equalsD4plusD5plusD6plusD7

1. the = sign which tells Excel that a formula or function follows
2. the function name such as SUM for addition or AVERAGE for determining the average of a series of numbers
3. the cells on which the particular function operates must be enclosed by parentheses, and it contains the cell references so that the function knows which cells to calculate
4. this naming logic is very similar to what we have seen before where a function is applied to a range of cells

### options for entering functions (or formulas, as well) into the spreadsheet

1. in the formula bar
2. directly into the cell
3. use the name box
4. OR use the Function Wizard to help you create the desired results The same is true in Excel for Mac • =SUM(D4,I48,V65)
• =AVERAGE(D1:D18)

#### Functions can perform mathematical operations on a group of cells

=SUM(D4:D7)
means
equalsadd togetherthe contents ofcells D4 through D7
or
equalsD4+D5+D6+D7

#### For argument of function:

if individual cells, use commas

=SUM(D2,D3,D5)
means

if a range of cells, use a colon

= SUM(F2:F4,F7:F17)
means
equalsaddF2 through F4 and F7 through F17together

Insert Function or fx function wizard or hit = and then the function draw down box. The Function dialog box has Function Category and Function Name plus a short explanation of what the function does. The same is true in Excel for Mac
