Using sigma sum notation to evaluate the partial sum

[@EliGlick-mw8nw]

I’m only in 7th grade at the time of this comment, but I enjoy learning in a fun way and your videos have been extremely fun for me to watch. I sometimes do really dumb things like bragging to my friends about knowing this (not to make fun of them) and see their reactions. It’s really hard to explain in only words but I just truly enjoy your content and hope you keep teaching.

I love your lectures but please make some videos on more complex problems.
