My name is Angela Morgan-Green and I am the creator of MathAngel369. I hold a Masters Degree in Applied Mathematics (2018) and a Bachelors Degree in Mathematics, minor in Chemistry (2008).
I have a career as a Lecturer in Mathematics (University); teaching since Fall of 2019.
Outside of work, I record math videos in my home studio so I can serve as a resource for others who wish to learn math on their own time.
In addition to my videos, I provide math discussions that include details and concepts of the examples discussed in my videos.
Lastly, I include hand written notes that I use to teach my college students. My notes contain an overview, concepts, and tons of additional problems solved, showing each step.
As a lecturer (2019-present), I have experience teaching traditional, online, and hybrid classes at the University level.
As a former Graduate Teaching Assistant (2017-2019), I have experience tutoring and teaching undergraduate students.
To be honest, I didn’t really learn math in school. During class, the lectures would go clean over my head. I had to teach myself and learn math alone.
On the upside to this, my struggles became my greatest strength because it helped me learn how to reach others who struggle in math the way I did.
I hope that my discussions, videos, and notes help you on your math journey!
Sincerely,
MathAngel369
