# Basic Operators

In this class, we will delve into basic Python operators, which are symbols used to perform operations on values and variables.

## Types of operators Link to heading

**Arithmetic operators:**They are used to perform mathematical operations such as addition, subtraction, multiplication, division and module.**Comparison operators:**They are used to compare two values and obtain a boolean value (True or False).**Logical operators:**They are used to combine boolean values and obtain a boolean value.

## Arithmetic operators Link to heading

`+`

: Sum`-`

: Subtraction`*`

: Multiplication`/`

: Division`//`

: Integer division`%`

: Module (remainder of division)

### Example Link to heading

```
# Addition
result = 10 + 5
# Subtraction
difference = 10 - 5
# Multiplication
product = 10 * 5
# Division
quotient = 10 / 5
# Integer division
integer_division = 10 // 5
# Module
residue = 10 % 5
print(result, difference, product, quotient, integer_division, residue)
```

## Comparison operators Link to heading

`==`

: Equality`!=`

: Inequality`<`

: Less than`<=`

: Less than or equal to`>`

: Greater than`>=`

: Greater than or equal to

### Example Link to heading

```
# Equality
equality = 10 == 10
# Inequality
inequality = 10 != 10
# Smaller than
less_than = 10 < 15
# Less than or equal to
less_than_or_equal_than = 10 <= 15
# Greater than
greater_than = 10 > 5
# Greater than or equal
greater_than_equal_than = 10 >= 5
print(equality, inequality, less_than, less_or_equal_than, greater_than, greater_than_or_equal_than)
```

## Logical operators Link to heading

`and`

: Conjunction (both values must be True)`or`

: Disjunction (at least one value must be True)`not`

: Negation (inverts the boolean value)

### Example Link to heading

```
# Conjunction
conjunction = (10 > 5) and (10 < 15)
# Disjunction
disjunction = (10 == 10) or (10 != 10)
# Denial
negation = not (10 == 10)
print(conjunction, disjunction, negation)
```
