Learned this in 5 minutes while the online school I'm learning from couldn't teach me in an hour. Absolutely bonkers Mario.

Mr. Mario, you've done it again! You teach me so much better than my pre-cal teacher! Can you replace her?

Another amazing video! Thank
Every video I have watched of yours has taught me what the online program I am in could not do, and in a matter of about 3 minutes. I have only found your videos because the program I am in just doesn't explain things well or fully and I am left to search the internet to explain a concept. You are my go to math teacher now. THANK YOU!

Thank you I have a test on this and my teacher literally doesn’t teach how to do it by steps. I learned last year and forgot how to do it on the review and she didn’t reteach it.

Do you have videos on symbol function? The type with squares, stars, boxes, etc. that require function work?
Thanks for your videos.
