Mathematical Expressions in Go

We can perform multiple calculations using operators in the same line of code:

fmt.Println(3 - 4 + 6) // Prints 5
fmt.Println(5 + 2 - 3) // Prints 4
fmt.Println(2 * 5 + 1) // Prints 11
fmt.Println(4 / 2 * 5) // Prints 10

We can also use variables:

num1 := 5
num2 := -1

fmt.Println(2 * num1 * num2) // Prints -10
fmt.Println(num1 + num2 - 3) // Prints 1
fmt.Println(20 / num1 + num2) // Prints 3
fmt.Println(num1 / 5 * num2) // Prints -1
