If I stare at your shirt for a long time I can feel my consciousness easing out of my very being, it is being attracted to the thresh hold of space-time, an endless ocean of knowledge and wisdom. I feel bliss as my soul is almost free, but I also feel fear as I delve into the deep unknown. Finally I look away from your retro shirt thinking to myself "Another day when I am ready to toss my consciousness into the unknown I will stare at your shirt and I will be truly free." Your shirt my friend is a gift, and it is also a curse.

That's good to hear, thank you for making these videos. The best way for me to learn math is here on KZread.
First and foremost, God bless you and your marvellous math help videos. I cannot tell you how many tests I've passed purely due to these videos! Also, have you ever been told how remarkably similar you look to Misha Collins? You could be his older brother, it's eerie! Anyway, thanks again for all of these, you are much better at explaining things than my math teacher!
I go to class everyday and get completely dazed and confused. Then I watch your videoS and you really clarify stuff up. I give you and you alone credit for helping me pass my College Algebra class. Thank you!

Hilarious when you open and end a video.. but how you explain the problems is even better! I really enjoy when you take the time to apply the problems to the real world - it helps a lot in grasping the concepts. Thanks so much for the tutorials!!!!

I don't think that you can still remember me since I used my another account but our first conversation was a year ago when I am just starting my first year of teaching. Thanks for all your advices they all really helped me along the way of my first year of being a teacher. "Maraming Salamat" (Thank You Very Much) from your fan here in the Philippines. God Bless You.
You're welcome and thanks for watching!
I love how you say if your in pre-calculus, and you allow for people in calculus and different classes that piecewise functions are used. I'm in calculus, but I also did them in pre-calculus so for me this video is great! I have an exam tomorrow morning, my first calculus test. I've got my limits pretty much down but I'm in need of some derivative videos!!!!
Thank you for the video you actually made piecewise functions understandable, I am in an online algebra 2 class and all the videos with the class where so convoluted it was almost a foreign language. Thank You SO MUCH
