Mr.J you dont know how much you helped me in life, I have been watching your videos since 11th grade when i was almost failing but then I came across your brand new account. I started getting better grades, until out of nowhere… I got a scholarship! I went to UCAL and studied law petroleum engineering, and im doing amazing in collage plus i already have my whole life planned out and will be making hundreds of thousands of dollars if God is helps me. So thank you so much - Tommy Pitzer

Mr.J thank you so much for teaching us. I’ve been watching you ever since 2nd or 3rd grade. Every time there is a lesson my teacher doesn’t wanna teach she pulls up you and says “My favorite part about this is I don’t have to teach it, he can” I just need to say these videos are SO SO SO helpful. My mom when I was younger pulled up a video of you and watched it to understand how kids are doing math. Thanks for teaching us Mr. J!! Love you ❤

I always hated and failed math because my teachers never explain properly so I never understood but after watching your videos, I love math now because you explain everything so well and I finally understand a lot of topics . Keep up the great work your channel is helping me a lot so far I have exams soon and for the first time I'm feeling very confident that i would pass.

Believe it or not. I did them all inside my head and got them all right!
It sure paid going back to school at the age of 28. Now pushing sixty.
Adult school really paid off. I need this stuff for abstract thinking in
my computer programming self taught skills on my part. Although,
you don't need to know algebra to do computer programming, but
you can learn variables a whole lot easier, learning algebra first. Which
I learned it backward, since I started my trek into computer programming
seven years before going back to school. I was 21, when I started programming
on an Atari 1300, then in two, short years, I moved up to the C128 Commodore
128 computer. Thanks Mr. J. You are sure a great help.

for #2, 16:15 why aren't the exponents being done before multiplication in this example? ie 3*18 i get that the answer is the same, in this case. is it because it's all the same function?

[rmann]

Can u do a video on more complicated expressions breakdowns as far as simplifying terms and linear equations and inequalities. It’s my most confusing topic I just can’t understand.

[AraebellaMwemezi]

Mr.jay is so helpful and has making me understand a lot more about math but in the next video u make can you please do two digit by four digit multiplication because I have no clue what to do and it would help a lot if you did

The only way I could do that was if you wanted me too I could come and pick you up and take you to the doctor 👩‍⚕️ if that was the only time you could come in for the surgery or the next one would you want to come in and pick you out and take you back or do I have a ride home and then you can come in and get me or I will take me back home 🏡 or whatever I just need you guys and I’ll come over to pick me out or you guys could just go out to dinner or something or something and I could do whatever I don’t want you to go out and I can go out and get something else I just want you to get something else you don’t want you guys can do it all depends what you’re doing and if I don’t care about me I just don’t want you know that you know that you don’t care what I just don’t want you don’t want anything to be with me I just don’t want to do what I just don’t want you can just say whatever I just want you guys are my life and if I can get out there is nothing wrong I just want you know that I just don’t care what I know you guys are just let it all I just want you know that works I just want you guys can talk about anything I want you guys know I don’t care what I want you guys are not talking to me I don’t care about anything else you know what you.
