Sir, you just saved my GPA by 2pts on at least 20 occasions

You are a very good teacher!. Greetings from Mexico

I see the good old lattice trick coming in hand, first used it in 4th grade for 3-4 digit number multiplication problems. Proud to see lattice works well with complex numbers so well! Thanks for the tip.

This man is saving me from failing Algebra 2 thank you man 😭

Best math teacher i've seen so far

Thank you so much for this video! I’m in an accelerated algebra 2 class, and sometimes it’s so quick that I don’t understand. I’ve been confused on this for a while, and this cleared up all my confusions!

You are saving my butt in my college algebra class. Thank you!

[justhuebloo]

It's so relieving to be able to finally understand the math after endless confusion in my actual class. Or what I mean to say is: thanks math dude.

[Lowgraphicsdeer]

Thank you, I have been struggling over this for a week because my teacher moves to fast and this cleared it all up

[hbog]

Thank you for this! Love how you teach.

Thank you so much for this. I didn't understand this at all when I first got to it and now I have a unit test. The first half was today and I realized just how much I needed to learn this. You truly saved me today!

Best math teacher on YouTube!! Thanks Brian!!

[quack_malard]

Thank you so so much. I have adhd and autism and I’m in advanced Algebra 2. My math teacher is not very understanding and treats me differently because of my disabilities, so I don’t get the help I need. You have saved my grade multiple times and I don’t know how to thank you.

I use foil instead of the box method, and you are still seriously saving my ass right now. I cannot tell you how my textbook and these slides described the multiplication and division process and the convoluted formula. I remember stumbling across your videos from Algebra and could have cried, lol.

[victorcallender]

Oh THAT WAS SOME GOOD LOOKING EASY UNDERSTANDING DELICIOUS KNOWLEDGE RIGHT THERE!!

[ceruleanb]

Ok I didn't even know the box method existed, it's much simpler than FOIL, so can the box method completely replace FOIL in all circumstances? Also I now realize what I was doing wrong, the conjugate always has the opposite sign, I was doing it with the same sign. This video was very helpful!

Thank you so much for your videos. Your explanations have brought me to the point of understanding the seemingly impossible.

[mtylnman]

Bro you’re better than my own teacher. Keep up the good work 👍👍👍

[catcraft]

Thank you so much! Your videos always help me out with math, I’m very grateful that I have videos like these to help me out.
