I've said it before, but boy do I wish your channel was around when I was helping my kids through their math courses. Your explanations are so clear and easy to follow. I'm watching to experience all the "hey, I used to know that!" moments.

In my opinion Andy Math and Mr H Tutoring are the best. The problems they demonstrate and solve do not rely on gimmicky short cuts. Also, they do not belabour the steps in a solution as many others do. I recommend them to anyone who asks me to help their kids with mathematics as a very good source.

Made it all the way through college linear algebra without really knowing this… somehow this 5 minute video is more helpful than a college course 😂😂

This is one of those situations where I remember learning about matrix math in college, doing well enough in the class, but not knowing at all how to apply it to anything. Now that I've been in my career for a couple decades now, I can now think back on many situations where I could see how this could have helped with data analysis and reporting.

Another specific engineering example would be circuit analysis. It's been a while since I've done it, but you can use it to solve Kirchoff's Voltage Laws.

A great way I saw matrix multiplication is to put the 1st one to the left, the 2nd one to the top - this way I'll see which rows should be multiplied with which columns.
