Sir, you are great teacher Because unlike any youtube tutorial videos your voice is loud and clear, your examples are brilliant and The best of all it's completely free... Thank you so much Sir You were such a big help for me

This video is a life saver. I want to say you taught this in a much easier to understand way than my teacher did in a week. Granted, I didn't pay much attention on Sines, but I did with Cosines, and I now have a clear understanding of both. My teacher never mentioned anything about Cosines being used on SSS and SAS triangles. You have a really good way of teaching this stuff. Good job!

Mario's explanations and examples are amazing. He makes learning the material so many times easier, and the fact that he's doing this for free and out of the good of his heart is amazingly gracious. He's the math teacher we all wanted, but didn't deserve. Someone give him a cinnabon

You have a great way of explaining things so that they make sense, giving the reason behind why things are being done and providing ways to memorize things in an effective way. Thank you for this gift.

I never understand my algebra and geometry teacher, and Mr. Mario, you always have the 10 minute videos that explain clearly what she tried to teach me in 2 hours. 😁
