 (ADVANCED - BASIC ARITHMETIC OPERATORS AND FUNCTIONS)



MEANING OF A FUNCTION

A function is a predefined formula that performs calculations using specific values in a particular order. All spreadsheet programs include common functions that can be used for quickly finding the sum, average, count, maximum value, and minimum value for a range of cells. In order to use functions correctly, you'll need to understand the different parts of a function and how to create arguments to calculate values and cell references.

THE PARTS OF A FUNCTION

In order to work correctly, a function must be written a specific way, which is called the syntax. The basic syntax for a function is an equals sign (=), the function name (SUM, for example), and one or more arguments. Arguments contain the information you want to calculate. The function in the example below would add the values of the cell range A1:A20.


FUNCTIONS                                         EXAMPLES/ARGUMENTS

1. SUM                         -                     = SUM (B2:G2)

                                                          = SUM (A2:A7, A9, A12, A15)

2. AVERAGE                -                   = AVERAGE (NUMBER1, NUMBER2)

                                                         = AVERAGE (B2:B11)

3. COUNT                   -                   = COUNT (A1:C1), = COUNTA (C2:C13)                

- This count all values that are

  numerical

4. IF                           -                      = IF (C2<D3, "TRUE", "FALSE")

                                                   IF (SUM (C1:C10)> SUM (D1:D10), SUM (C1:C10), SUM (D1:D10)

5. MAX & MIN       -                  = MIN (Number1, Number2)

* This finds the maximum and    = MIN (B2:C11)

minimum number in a range of   = (B2:C11)

 values

6. PRODUCT     -                        =PRODUCT(A1, A2) 

                                       = PRODUCT (A1:A5)

                                       = A1*A2

7. DIFFERENCE          "=A1-B1"


CLASS ACTIVITY

* PRACTICAL
