Ur the reason I’m not failing classes. I actually understand how to do it when u explain. Thank u!!!
Are you in the 8th grade
yeah, because sometimes I cannot understand my teacher
😂😂😂😂 true man true
@@vmartins2234 yeah me too but im on 7th grade... im to shy for me to explain in my teacher and i still dont get it.
@@deirahheartmesina4274 it's ok. I was the same tho
*thank you man you truly are big brain thank you for enlightening my small brain*
you literally fit a 4 hour class' worth of information in about 15 seconds or so, thank you so much mate
THANK YOU!
Literally on the verge of a test in 20 minutes and I still didn't know how to get this down! Thankfully you came in perfect timing and now I understand and might pass my test! 🙏🏽
I hate how some teachers of text books don't teach in simple levels
Did you pass?
@@jordanbryant1062 Lol, I passed the part with these equations but it was a science test about the elements and molecule type stuff… in the end I got like a 78% 💀😭
I’m not smart in that area okay? 🥲
But uh yea technically i passed but I would of liked if it was better
@@Yoyo-ey4sd same here
I'm kinda in the same problem too rn....
Thank you for assisting me with teaching my most challenging classes. For some reason, the students are quiet and listen to you. I'm grateful for you. Then I get to walk around the room and help the students that need personal attention. I've never believed in playing videos for instruction inside the classroom. It has been a game changer. I stop the video after you write out the problem and give them time to think about how they would solve it. Again, thank you!
Cmon man, this guy deserves more recognition. This is Amazing.
Thank you so much. I'm in the advanced math class, and I've got a test on everything we learned last year, the first week of school. I had gotten my second vaccine when we were learning scientific notation and had to go home because I had a fever and couldn't make it through the day, therefore, I learned the method wrong. This just saved my grade on the upcoming test, so thank you ^^
doing modules on my own without any sort of discussion from my teacher is making me feel DUMB but thankfully i found this yt channel. Thankyou so much for sharing your intelligence to us for free. You're amazing God bless you!
blud what that has nothing to do with this and lol im muslim@@CalebBerman
i'm already in college and I already forgor 💀about this. I remember back then how I was going through this video to understand it. So grateful for this channel to always have my back after all these years.
It’s so hard, right😭
I have a test tomorrow and I didn’t understand this but now I do you’re a life saver dude!
I have a quiz tomorrow and this absolutely saved my life thank you so much
Did you pass?
Did you pass
had no clue what my instructor was telling me when he was "teaching" this. first video i find about the subject, and it made perfect sense. thank you !
I didn't think this would help until I tried it on my own work, thank you. You're a lifesaver
Omg thank you!! You're the most clearest out of every video I watched
Brother, you are literally a life saver. You explain these concepts such simply, i thank you for your time in making theses videos, kudos!
Better explanation of adding and subtracting exponent 👍
love from India 🇮🇳🇮🇳
Excellent
Fabulous .
I was worried because i couldn't understand these sums but after watching your video My concept is clear in addition and subtraction .
Thank you so much!
Keep it up
May Allah bless you!
👍👍👍👍👍👍
This was on my first assignment for physics, thank you for this life saver!
Who’s here for online school?

ME! 🤦🏻♀️🤦🏻♀️
Im dum
Me 😭😭 it sucks because I get so unmotivated but I can’t afford to fail any classes

Other videos were too fast and unclear but you taking your time to explain every bit and showing me the whole picture makes me understand it tysmm.
Dude I have join in this crowd appreciating you cuz u helped me on the last second so many times u truly are a life saver

The explanation is really easy to grasp along with some questions which you give us to try ,I'm very thankful to you sir may God bless you you've been a great help.
You just taught me more in 7 minutes than my teacher in 2 weeks lol. I wish math teachers just showed your videos instead of teaching it ThEiR wAy :/

i literally have a test in 1 hour and i don’t know how to do any of this. thanks for the hellppp 😃🔫
I hope your test went well.
doing my chem hw rn and i want to die lol😀👍
I literally have a math exam tmrw and it’s scary how I understand from him but not my teacher:)
@@gotmespinninglikeaballerina Oof- how did it go?
@@pumpamberrypum5847 it went great! Tysm for asking
Overall, I loved the video. Very clear explanations. One quick comment; in the beginning you were talking about '9x' and '5x'. This might be a little confusing, since the 'x' isn't a variable in scientific notation; it's a multiplication sign. The operation isn't a part of the value, so it should just be 9-5, not 9x-5x.
Watching this three hours before my test . Thanks so much 🙏
Dude thank you! So well explained, unlike Sal Khan which i rewatched his video in this topic 3 times yet still had no clue what he was talking about, and all the comments there are also confused. I hate the way he explains things so passionately.
I may be 2 years late but I could never thank you enough thanks!!!!!
Brother! I am immensely indebted to you..... Love and blessings from Pakistan.
This really helps! Especially during 2020!!
I'm just going to say thank u. You help me out a lot in life 😅
This is a lifesaver, thank you!
Already done this, then have a final exam six months later and now its that time, but i forgot it, u just single handedly saved my grade. THANK U!
thank you for providing such a simple and easy to understand explanation! was really struggling to understand the reason why
This is a very helpful video! Thank you
Thanks,! Ive gone back to school after 25 years, and my instructor is horrible at teaching, Im in my last two weeks, praying Ill pass the finales. This has helped!

Dude I would pay so you can teach me. Your actually the best♥️
You saved my life. Thankyou so much.

I’ve always had a problem with scientific notation I don’t know why.. this is my third time reviewing in after 2 years and I still have to watch videos
Same don’t even worry man I have the same problem like ik it’s easy but I just have problems with it, and I’m the same way with negatives I just can never figure it out.
This online stuff is hard but i find your videos and it helps me. Thanks

This is the teacher that helped me a lot :) thank u!!
Bro, you just made a 30 min lesson into 4 mins. And my teacher only taught about how to add and subtract the ones with the same exponent! TYSM ! ! ! ! !! OMG

This was really helpful, thanks!

Thank you so much for this video.......it was really really helpful
Thanks man love you first I was confused but now it's cleared
Absolutely love it man ❤
what if the exponent is negative😢
if it's like 2 ^ -3 then you go 1/ 2^3 ( and that will make the negative a positie :D
@Crystal Gobea thanks

@Syeda Zehra what if its a huge difference? like 10^19 and 10^31?
