How do i use comparison operators in a bash shell script?

[shoebill]

The comparison operators are <, <=, >, and >=

Which read:
< less than
<= less than or equal to
> greater than
>= greater than or equal to

if (( 10 < 2 ));then
echo "Running calculation 1, That's true!"
fi

if (( 10 <= 2 ));then
echo "Running calculation 2, That's true!"
fi

if (( 10 > 2 ));then
echo "Running calculation 3, That's true!"
fi

if (( 10 >= 2 ));then
echo "Running calculation 4, That's true!"
fi

Running the script give the following results:

$ ./arithmetic.sh
Running calculation 3, That's true!
Running calculation 4, That's true!
