This document provides an overview of functions in Excel, including common functions such as SUM, PRODUCT, QUOTIENT, AVERAGE, MAX, and MIN. It explains that functions can perform calculations on numbers, cells, or ranges of cells and uses examples to demonstrate how to write functions using numbers, individual cells, or ranges. Functions provide shortcuts for common calculations compared to writing out formulas.

1. Using Functions in Excel

2. Review
A FUNCTION is a built in formula that is a shortcut for common
calculations.
Example:
=SUM(A1:A20)

3. Types of Functions
Excel places functions in various categories

4. Common Functions
In this class we will use a few common functions

5. Common Functions
SUM - Adds the contents in the range of the function
PRODUCT – Multiplies the contents in the range of the function
QUOTIENT – Divides the contents in the range of the function
AVERAGE – Finds the average of the content in the range
MAX – Finds the largest value in the range of the function
MIN – Finds the lowest value in the range of the function
ABS – Returns the absolute value of a number

6. Common Functions
There is NO function for subtraction in excel

7. Using Functions
Functions can be used in the same ways that formulas are used

8. Using Functions
Calculation for numbers by themselves.
Example: Gives the sum of the numbers 1 and 3
=SUM(1,3)

9. Using Functions
Calculation for numbers and cells.
Example: Gives the sum of cell A1 and the number 3
=SUM(a1,3)

10. Using Functions
Calculation for cells.
Example: Gives the sum for the range of cells a1 through c1
=SUM(a1:c1)

11. Using Functions
IMPORTANT!!
When using NUMBERS with functions; use a comma
=SUM(1,3)
When using cell references with function, use a colon
=SUM(a1:c1)
