• # Operators

Logical operators in programming are like a set of tools that help us decide what to do depending on how things look. Logical operators tell the computer to do something based on how two different things compare.

• The addition operator returns the sum of two variables.

• #### Go

##### Example of addition operator in go.
``````package main

import "fmt"

func main() {
var age int = 20

fmt.Println(age + 1) // 21
}
``````
• ## Subtraction Arithmetic Operators

• The subtraction operator returns the difference of two variables.

• #### Go

##### Example of subtraction operator in go.
``````package main

import "fmt"

func main() {
var age int = 20

fmt.Println(age - 2) // 18
}
``````
• ## Multiplication Arithmetic Operators

• The multiplication operator returns the product of two variables.

• #### Go

##### Example of multiplication operator in go.
``````package main

import "fmt"

func main() {
var age int = 20

fmt.Println(age * 3) // 60
}
``````
• ## Division Arithmetic Operators

• The division operator returns the quotient of two variables.

• #### Go

##### Example of division operator in go.
``````package main

import "fmt"

func main() {
var age int = 20

fmt.Println(age / 2) // 10
}
``````
• ## Modulus Arithmetic Operators

• The modulus operator returns the remainder of two variables.

• #### Go

##### Example of modulus operator in go.
``````package main

import "fmt"

func main() {
var age int = 20

fmt.Println(age % 9) // 2
}
``````
• ## Exponentiation Arithmetic Operators

• The exponentiation operator returns the power of two variables.

• #### Go

##### Example of exponentiation operator in go.
``````package main

import (
"fmt"
"math"
)

func main() {
var age float64 = 2

fmt.Println(math.Pow(age, 3)) // 8
}
``````
• ## Equal Comparison Operators

• The equal operator checks if two variables are equal value.

• #### Go

##### Example of equal operator in go.
``````package main

import "fmt"

func main() {
var age int = 20

fmt.Println(age == 20) // true
}
``````
• ## Equal Type Comparison Operators

• The equal type operator checks if two variables are equal value and type.

• #### Go

##### Example of equal type operator in go.
``````package main

import "fmt"

func main() {
var age string = "20"

fmt.Println(age == "20") // true
}
``````
• ## Not Equal Comparison Operators

• The not-equal operator checks if two variables are not equal value.

• #### Go

##### Example of not-equal operator in go.
``````package main

import "fmt"

func main() {
var age int = 20

fmt.Println(age != 18) // true
}
``````
• ## Not Equal Type Comparison Operators

• The not-equal type operator checks if two variables are not equal value and type.

• #### Go

##### Example of not-equal type operator in go.
``// NA``
• ## Greater Than Comparison Operators

• The greater-than operator checks if the value of the first variable is greater than the second.

• #### Go

##### Example of greater-than operator in go.
``````package main

import "fmt"

func main() {
var age int = 20

fmt.Println(age > 18) // true
}
``````
• ## Less Than Comparison Operators

• The less-than operator checks if the value of the first variable is less than the second.

• #### Go

##### Example of less-than operator in go.
``````package main

import "fmt"

func main() {
var age int = 20

fmt.Println(age < 21) // true
}
``````
• ## Greater Than or Equal Comparison Operators

• The greater-than or equal-to operator checks if the value of the first variable is greater than or equal to the second.

• #### Go

##### Example of greater-than or equal-to operator in go.
``````package main

import "fmt"

func main() {
var age int = 20

fmt.Println(age >= 20) // true
}
``````
• ## Less Than or Equal Comparison Operators

• The less-than or equal-to operator checks if the value of the first variable is less than or equal to the second.

• #### Go

##### Example of less-than or equal-to operator in go.
``````package main

import "fmt"

func main() {
var age int = 20

fmt.Println(age <= 20) // true
}
``````
