How to calculate other math functions?

You can calculate various mathematical functions in Linux using the bc command or other tools like awk and python. Here are some examples:

Using bc

1. Addition:

   echo "5 + 3" | bc
   

2. Subtraction:

   echo "10 - 4" | bc
   

3. Multiplication:

   echo "7 * 6" | bc
   

4. Division:

   echo "scale=2; 10 / 3" | bc
   

5. Exponentiation:

   echo "2^3" | bc
   

Using awk

You can also use awk for calculations:

1. Addition:

   echo | awk '{print 5 + 3}'
   

2. Square Root:

   echo | awk '{print sqrt(25)}'
   

Using python

If you have Python installed, you can use it for more complex calculations:

1. Basic Operations:

   python -c "print(5 + 3)"
   

2. Square Root:

   python -c "import math; print(math.sqrt(25))"
   

3. Exponentiation:

   python -c "print(2 ** 3)"
   

These methods allow you to perform a wide range of mathematical calculations directly from the command line.
