GBU 💟 You just gave me a significant hope to pass the PSY enterance exams. Just before I was to "decide", that stat is not my thing, I found myself understanding & loving those formulas. Appreciate so much.

God bless you. You make this so calming. I am relearning math and I need the handholding

[@irfan150ful]

This is Great video 👍 so simple & much better to understand than any other videos…hope you create more video like this😊

[@hennatherapy305]

You made it look so easy, thank you😁

[@trecynsp]

Wow this was easy. Thank you so much. Wish you had more videos.

God bless you ma'am
You touched my life with this video.

[@fahadreda3060]

Thank you for an easy explanation

[@PimpMatt0]

Took me awhile to get it but I get it now. I've only done summations in precal and calculus but never really understood how to read the symbol with clarity.

Thank you so much!!❤

this Really Help me Alot Arigathanks :D

[@linajichi3543]

Thank you soo much

[@alliah.00]

thank you

[@arbitrarylib]

Please make more videos please!! But no music through the examples. It throws me off. Also, why do you only sometimes write xi next to the Greek add symbol?? Is that just you deciding to leave it out?

[@DEMONIZEKYO478]

If u explain it instead of playing music in the background would be much better.just my opinion.

[@christiejb]

[@johnphillipescaleragrino8935]

i wasnt helpful

[@ussr7709]

i just wasted 3 min of my life skimming threw this

[@Dravidconoodle]

no music please its distracting the learnings

[@duckyoutube6318]

Here are some of the things i want to know.
I already know how to find the sum of any set of countable numbers i.e. 1+2+3+4+5 ect...
But what i want to know is...
X^2
X^3
X^4
And i want to see if there is a relationship between those sets so i can then calc the sum for all series of X^n
And then i want to learn the same thing but with logarithms and square roots, imaginary numbers, complex fractions like 1/x and 1/x!
x!
1/x!
And then i want to know the sums of prime functions. Like...
f'(x) when f(x) = x! Or 1/x! or 1/x^2
