Thank you so much Ginger man, you have done in 4:29 minutes what our university lecturer has failed to teach us in 4 months. Love you x

I had no idea my calculator was this POWERFUL thank you so much for this video now I won't suffer in my chem lab 🤗

[@evangelinmurmu8790]

why cant teachers teach as well as you. It took me a few minutes to understand this, yet it took me 2 hours to understand what the teacher was saying in school and even then i still did not full understand it. good job

[@666davidfrench]

I have just learned more from this video than I did in 1.5 hours at college 🤪

[@mashalkhan8261]

i have learnt more in 1 millisecond of this video than memorizing the entire wikipedia data archives

[@amikanooshabadi9197]

I can not be more thankful for this. I was in a lecture and the teacher was going through this on her calculator and I was sitting there like a lost lamb until I came across your video and quickly watched it. Thank you so much!

[@k.iskandar]

You saved my life buddy. You pulled your hair trying to figure this out? I almost scalped mine. Well done for figuring it out and thanks for sharing this. You saved my life ( and my scalp).

[@N-Kiro]

My uni couldn’t teach me this, but a man on the internet has done it in 4 minutes. A 4 minute long 8 year old video, has just taught me more than my university did in a whole year.

[@aberedfield5820]

Dude, this video was exactly what I needed. You explained this in such a simple way. Was stressing about a stats quiz as I have been calculating all of this by hand, manually entering each equation and it takes ages! You're a lifesaver :-)

[@jinwahlowe1115]

You are my hero, I was stuck in my math class being the only one with a Casio and no one knew how to do standard deviation on it

[@Denis5966]

This was/is a huge help Justin. Thank You. Saves a lot of time before an exam.

[@isobellarollorenn6164]

you helped me 10 min before my exam on this and i got an A+ so thankyou

[@mashalkhan8261]

holy shit i got scored an instant 1600 on my SATs after watching this for an entir 10 seconds

[@amankinfe5570]

my exams are gonna start next week (prepared by my college). and you my friend have explained the whole thing in less than 10 minutes. thank you very much!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! you are my saviour

[@elleJay-mb4yn]

I have an analytical chem exam next week, this helped me so much. I was calculating manually which took soooo much time. Great vid!!

[@owright5129]

Thank you soooo much. I am a maths teacher and my 17 year olds all have this calculator. This was a very simple way to help them help themselves.

[@robertjohn2220]

Well Done, thanks for the video. I was scratching my head trying to work this out. 4.5 minutes with you and I am done, Fair play to you
