Thank you so much for doing this video! I was really stuck and am not a quick study when it comes to math. Your straightforward explanation got me unstuck and helped me figure out and finish most of these type of problems in my practice assignment. Really appreciate you!

You are the best math teacher ever. As long as I have you I will pass my math classes

Fantastic video - I can't overstate how your little jokes throughout the problem solving process made it easier to approach this as a non math oriented person
