Small Perl script needed (Ubuntu)

Need a small Perl script created with screenshots on the various steps for informational purposes. The instructions are as follows: 1. Practice a simple command-line calculator. See the sample output above. • Use the read command twice to prompt users to enter two integer numbers. Save them to two variables. • Display the sum, difference, product and quotient of these two numbers. 2. Write a script to get the sum of all numbers from 1 to n, where n is an integer provided by users (if not, default to 10). 3. Write a script to display the following patterns on the screen. Number of rows and columns are taken from the command arguments; if they are missing, set default to 3 (rows) and 4 (columns). Hint: you will use a nested loop. **** **** **** 4. Explain any differences of the above vs doing it in BASH
