Brett, I love the way you present the lesson in easy to understand terms. I tutor Hispanic students in math in order to pass the GED section. I try to do what you do by presenting simple examples. I “borrow” your examples to supplement what I do. Thank you. I also love the “beauty” of math but not strong in it myself. I actually “study” calculus in my “spare” time just to understand the “beauty” of what Newton created so he could describe nature. You perform a wonderful service. Keep it up. Retired and enjoying my time in helping others in math.
