It’s funny how my teacher takes 40 min to explain this and I barely remember but this does it in 2 min and it’s etched in my brain

[carleigh]

i was in a math crisis and this helped me more than my math teacher which took 1 hr to explain rather than 2 mins that i actually understood

[lisabudzisz]

I was really struggling with this. You explained it very clearly. Thank you!

[ivansowatzka]

Thank you so much, I had a homework crisis at 1am and this helped me so much

[ellagood]

Thank you so much! My mom and I had no idea what we were doing, you helped a lot 💙

[meep]

Thank you so much! I have been trying to understand this concept for awhile and have never been able to understand until this video!

[disappointment]

This helped me understand my math homework, thanks for explaining it more clearly than my math teacher

[kaykayesJr]

Thank You Sir, I have a SOL math test tomorrow and this year had been tough. I have not learned anything and i'm trying to cram a years worth of learning into 1 night. I will probably fail the test but its always worth a try, I am going to check out some of your other videos and I will edit this comment and give and update about how I did tomorrow.

THANK YOU SO MUCH! May God bless your soul. You have no idea how long I've been struggling on this topic.

Nice job bro. Also, I saw one or two hate comments in this section, don’t mind them. Thanks for doing a service for our community. Also, this helped me a lot! 👍

[starkermine]

Why cant all math teachers teach this fast, it takes mine 40 mins and you explained it perfectly in 3 mins

[laurajones]

You have such a lovely spirit and a way of expressing not just what to do, but why you are doing it, which is exceptionally helpful for someone who is not math inclined like myself. I so hope you are doing well, and please know that today as I am working on an assignment in my masters program, your video not only helped me accomplish the task, but it did while filling my heart. Much appreciated :)

This helped me so much, I really appreciate you! Also I don't understand how a 2 minute video makes me understand everything but when my teacher speaks for 1h 20m i don't understand anything.

[maryellenreed]

Thank you for being so clear!! Great video!

[hii-lvni]

[angelamassage]

[kittybri]

Wow, your very clear! This is going to help me for my math test! Thank you!!

Yay! I know how to do this now! I like how you just get straight to the point, show us the formula and examples, and then point out some mistakes. Gj
