EXCEL FUNCTIONS-OR

INTRODUCTION

OR function comes under the LOGICAL FUNCTIONS category in Excel.

OR function is very important and is going to be used a lot which makes it one of the very important functions in excel.

It simply behaves like the binary OR.

It checks if ANY OF THE CONDITIONS are TRUE OR NOT.

IT returns TRUE if ANY OF THE CONDITIONS ARE TRUE and false , if ALL of the conditions is FALSE.

PURPOSE OF OR IN EXCEL

OR FUNCTION RETURNS TRUE IF ANY OF THE CONDITIONS ARE TRUE AND FALSE IF ALL OF THE GIVEN CONDITIONS ARE FALSE.

PREREQUISITES TO LEARN OR

THERE ARE A FEW PREREQUISITES WHICH WILL ENABLE YOU TO UNDERSTAND THIS FUNCTION IN A BETTER WAY.

Some information about the BINARY MATHEMATICS is an advantage for the use of such formulas.
Basic understanding of how to use a formula or function.
Basic understanding of rows and columns in Excel.
Of course, Excel software.

SYNTAX: OR FUNCTION

The Syntax for the function is

=OR(CONDITION 1, CONDITION 2, CONDITION 3, …… SO ON)

CONDITION1 Any condition (e.g. if any cell>12)

CONDITION2 Any condition (if any cell <45)

Atleast TWO CONDITIONS are needed. At the most, any number of conditions can be used.

EXAMPLE:OR FUNCTION IN EXCEL

DATA SAMPLE

Suppose we have a cell which contains a number.

Suppose we are trying to make a group of the people with ages

<20 and greater than 50.

For this case, we can use OR function as we have to select the person when either of the conditions is true.

STEPS TO USE OR

The example has 8 persons with ages given in the next column.

We are checking if the age is fulfilling the requirement for the selection which is, the age needs to be less than 20 or greater than 50

The formula is used as

=OR(G4<20,G4>50)

for the PERSON 1 and goes like this. for person 8 it is

=OR(G11<20,G11>50)

The cell number is the cell which contains the age of a particular person.

KNOWLEDGE BYTES

BINARY AND

BINARY MATHEMATICS have just two number-0 and 1.

Its just like the DECIMAL SYSTEM which we use in day to day life which has ten numbers 0 to 9.

So OR is known as the BINARY ADDITION. As we can understand easily that

0+0=0

1+0=1

0+1=1

1+1=1

where 1 is TRUE and 0 is false.

Same goes in this function. When any of the conditions are true, we get TRUE result.

DIFFERENCES: AND vs OR

AND is binary multiplication whereas OR is binary addition.

AND needs all the conditions true to give TRUE as result.

OR needs any of the condition true to give TRUE as result.
