A short explanation on the use of the following functions: IF, AND, OR, NOT

## The IF function

### The isolated IF function

*"If the note in A1 is greater than or equal to 19, then display the number 20, otherwise display A1"* can be expressed as:

** =IF(A1>=19;20;A1) **
*"If the data in A1 is "Reset", then subtract 10%, otherwise keep A1"*, can be expressed as:

**=A1*IF(A1="Reset";1-10%;1) **
### Nested IF functions

*"If the note in A1 is greater than 12, then display "continue"; if A1> 18, then add "that's fine" or display "satisfactory". But if A1 <= 12, then display "to be improved" *, can be expressed as

**=IF(A1>12;"continue, " & IF(A1>18;"that's fine";"satisfactory");"to be improved") **
or the using the following formula:

**=IF(A1<12;"to be improved";SI(A1<18;"continue, satisfactory";"continue, to be improved")) **
*If the note in A1 is less than 4, then display "nil"; if A1 is between 4 and 8, then display "not enough"; if A1 is between 8 and 12, then display "mid"; if A1 is between 12 and 16, then display "good", otherwise display "very good"*, can be expressed as:

**=IF(A1<4;"nil";IF(A1<8;"not enough";IF(A1<12;"mid";SI(A1<16;"good";"very good")))) **
## The AND function

*Display "The Countess" if all these conditions are met: A2(sex)=female, B2(status)=married, C2(husband)=count and D2(score)=present, otherwise display "Hello" *can be expressed as:

**=IF(AND(A2="woman";B2="married";C2="count"; D2="present");"The Countess !";"Hello") **
## The OR function

*Display "Drive" if A3 contains the following data: plane, formula 1, moto, display "Driver" if A3 contains "car" or "work" otherwise display "?"*, can be expressed as:

**=IF(OR(A3="plane";A3="formula 1";A3="moto");"Drive";IF(OR(A3="car";A3="work");"Driver";"?")) **
## The NOT function

*=IF(INT(A3)=A3;"integer";"decimal") *can also be written as

**=IF(NOT(INT(A3)=A3);"decimal";"integer") **
*=IF(A4<>"french";"foreigner";"european") *can also be written as

**=IF(NOT(A4="french");"foreigner";"european") **
## Combinations

The AND, OR and NOT are commonly used in association with the IF function.
