      How do you write on that board and display it? Surely you're not writing backwards?

    Hello, Jeff Chasnov, I am a Libyan student from the University of Sirte. I would like to extend my thanks to you because you have conveyed the information to my brain smoothly, and I hope that we have competent professors just like you...... Thank you.🤗

    Thank you so much! Unlike other videos, you explained what you needed to do AND why you needed to do it. You even answered questions I didn't know I had. Amazing video 10/10
