Write a self-executable bash script that takes two integer arguments, multiplies and divides them (integer division), and prints both of these results.

Some example executions of the script would look as follows:

$ ./script.sh 10 2
10 * 2 = 20
10 / 2 = 5

$ ./script.sh 10 3
10 * 3 = 30
10 / 3 = 3
