What are other arithmetic operators?

In Bash, several arithmetic operators can be used to perform mathematical calculations. Here are the most common arithmetic operators:

Addition (+): Adds two numbers.
```
result=$((5 + 3))  # result is 8
```
Subtraction (-): Subtracts the second number from the first.
```
result=$((5 - 3))  # result is 2
```
Multiplication (*): Multiplies two numbers.
```
result=$((5 * 3))  # result is 15
```
Division (/): Divides the first number by the second. Note that this performs integer division.
```
result=$((5 / 2))  # result is 2
```
Modulo (%): Returns the remainder of the division of the first number by the second.
```
result=$((5 % 2))  # result is 1
```
Exponentiation (**): Raises the first number to the power of the second number (available in Bash 4.0 and later).
```
result=$((2 ** 3))  # result is 8
```

Using Arithmetic Operators

You can use these operators within the $(( )) syntax for arithmetic evaluation:

a=10
b=5

sum=$((a + b))          # Addition
difference=$((a - b))   # Subtraction
product=$((a * b))      # Multiplication
quotient=$((a / b))     # Division
remainder=$((a % b))    # Modulo
power=$((a ** b))       # Exponentiation

Summary

Bash supports various arithmetic operators, including addition, subtraction, multiplication, division, modulo, and exponentiation, which can be used for performing mathematical calculations in scripts.
