About blackpenredpen


My name is Steve and I am the creator of the math channel blackpenredpen on YouTube. My goal is to continue making math videos (algebra, trigonometry, calc1, calc2, differential equations, and math for fun), worksheets, wallpapers and t-shirts for whoever loves math or wants to learn math.

I want to grow the channel but I do run the channel on my own. If you believe in what I do and have been enjoying my videos, please help me to share my channel with other math enthusiasts and consider to support my channel on this Patreon page.

Thank you,
