many thanks to you sir, im attending university and have been struggling with scientific notation and for some reason you have made me understand it when my professor has not been able to. THANK YOU THANK YOU THANK YOU
@Zachary Grubb Yes, here is a fun fact. Make sure you learn it in whatever grade you are in if you plan to go to University. By the way, I am now a University grad and have been working in my field for a few years now.
Yes, it HAS to be only one number to the left of the decimal point. If you have more than one, for an answer like 45.3 x 10^3, it's not right, and you have to change it to 4.53 x 10^4.
Lol I got confused cause my algebra teacher said to use the smaller number exponents and told me to go right.....so I tried my teachers way and than played the video to find the answer and I was still correct so xD would this matter tho in another algebra class?
I'm a control systems engineer and I know math, and this young man has great skills as a math teacher. I'm always looking for better ways to explain what I do to the technicians and electricians that work for me and this young educator has given me some great tips. Awesome video!
Just want to let you know that I'm studying for a chemistry test on all of this stuff tomorrow and it's very overwhelming, especially having to do all of the math on paper and making sure that's all correct. Your videos help me so much and probably are going to boost my test grade so much! Thank you!!!
I am going back to school and have to retake chemistry to better my GPA. In 2017 I used all your videos to help better myself at chemistry. Now that its 2022 I am still coming back to your videos. Thanks much for putting these together.
@vision57 well first, i moved the decimal to the left, not to the right. that makes the exponent on ten BIGGER. and -10 is SMALLER than -8, because they're NEGATIVE, right? remember, for example, -2,000 is lower than -2. take -10 and add one (-10 + 1), you get -9. take -9 and add 1 (-9 + 1), you get -8. so -8 is two bigger than -10.
absolutely you're forgiven. i was just having a really bad day, too. but i appreciate your apology and i hope you'll accept one from me. i'm glad the other video was helpful. message me if you still have questions.
@imarghoob go to 3:37, where i say, "i'm not using significant figures for these calculations." significant figures make everything more complicated, and i'm just trying to teach the basics here. if you're already good with sig figs, apply the rounding rules yourself.
yes, but these are NEGATIVE numbers. i'm moving the exponent from -10 to -8 by moving the decimal to the right. -8 is BIGGER than -10 because they are negative numbers. for more help, watch my videos called "scientific notation practice problems" and "fixing incorrect scientific notation."
Thank you so much! During this whole "pandemic" thing I'm doing online school and my Physical Science teacher is not the greatest with technology. She's also been having difficulties with software so that doesn't help. However, this was a great help in getting my homework done so thank you!
Please respond! I had to stop the video just to comment and say how good of a teacher you are. Thank you so much! Oh my goodness! You're such a great teacher, you break things down and tell us what has to be done in such an easy way! My teachers don't do anything like you... My chemistry teacher gave us homework like this last day and expected us to know and complete it and i was like what the hell. Thank you so much, my homework is much more fun now! haha!
Well since it's a negative number making the actual number itself smaller makes it less negative there for its bigger. The bigger the negative number is, the smaller it gets and vice versa
I cannot stress highly enough the contribution you have made to students everywhere. Thanks ever so much for your wonderful teaching style. I have special needs and I am doing great now because of your videos. Humble and sincere thanks
@awztukat you're completely good. it's just a negative number, nothing to worry about. you can write both positive and negative numbers using scientific notation.
You're the best! You explained this concept so clearly. Liked the graphic for adding and subtracting exponents. This will help my son a lot! Thanks for sharing your gift. l
Very nice video! But at 2:37, while one can increase or decrease the exponent while moving the decimal place in order for the same powers, would it actually matter of the choice of choosing which one to change?
Jesus, it took me so long to get this concept and I'm almost failing my class but then there's this video i could've used for the past week. Very nice.
Or you could just move 2.9785 x 10-8 to the right ?? Right ?? So that the exponent will be x 10 -10 ? Then the answer will be 292.13 is this also an correct answer ??.
joed acilo yes as it will be 292.13 x 10^-10 which is equal to 2.9213 x 10^-8. He does it to 8 however as usually in scientific notation you only have one number on the left of the decimal. Hope that helped and sorry for being 4 years late 😆
im a newbie in teaching and i need a lot of catching up to do..i am not a chemistry major but i have been given loads in chemistry..THANKS TO YOU!You made my preparation for my lessons easier. God bless...
Thank you sooo much for your videos on scientific notation! I took an AP practice test (my real one is tomorrow ) and got several wrong since my teacher spoiled me all year and let my class usually use a calculator for the MC. I got so confused; now your video helped me a lot!
Thanks so much for this great video! Finally someone who I can understand! And now you got a extra sub! I got a quiz tomorrow on this and a bunch more of exponent stuff and this helped me so much! Thnx! Ya da best! :) Rate up if true lol.
Thank you so so much. Can I just say you are an amazing teacher! It's unbelievable how you made these concepts so easy to grasp. My chemistry teacher teaches these things and it makes me so confused. I'm so glad you make these videos. I look forward to you doing more of these!
Yes, when you move to the left the exponent gets bigger. So -10 becomes -8 when you move to the left two spaces. See when you go from -10 to -8 the number is actually getting bigger because you're getting closer to 0. Lets say your number is going from -8 to -10. Then your number would be actually getting smaller. Remember that when you are counting in negatives it's opposite to counting in positives.
do it in two steps. follow the instructions here for adding the scientific notation, so do that and get an answer. and then follow the instructions in "add and subtract with significant figures (1.6)" for how the round the number you get. you'll be rounding the first part of the scientific notation, and you don't do any rounding with the 10 and the exponent.
Question. When equalizing the exponents, should I make the decimal smaller and lower the bigger exponent, or should I make the other number bigger, and raise the lower one?
A very easy to follow explanation particularly when needing to convert exponents that are different so that they can be added or subtracted. Have subscribed.
Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
Thank you Tyler Dewitt. I paid $900 for my CHEM 101 course, and I have a textbook and a prayer. I guess you answered my prayer! LOL. Seriously, thank you. Why is my professor doing nothing...
legit your the man thanks i needed help this video is so sick and appreciate good people like you on youtube helping kids like this thanks for making it so simple
Hi loved the video but one concern i had was the last example you gave. would it have mattered if i moved either to the left or right to get that 1.4 ? Thank you, i hope you see this
Thank you very much man I'm in 9th grade and this is a video from 10 years ago and it helped me like wow we are now in 2020 the year when the worse virus had an outbreak *corona virus* and it still helped me thank you so much.
Don't worry, as I understood it, Luke Reynolds was calling *me* the idiot, because he didn't watch my video far enough through to see that I did example problems with different exponents.
Hope you didnt answer this in the comments already but how do you know which exponents to choose? On the -8 and-10 example why did you choose -10 why not go right to make the -8 to -10?
Just a question, which exponent are you gonna change? The one with least number of decimal places or the one with the greatest number of decimal places?
As long as your final answer has a scientific notation that has one non zero digit to the left of the decimal point, both final answers will be the same, so it doesn't matter which number's decimal place is changed.
when subtracting or adding the quantities with unlike powers is it mandatory to change the powers to the power with the lowest digit? (lowest digit but greater value)
wow i was so lost before i found this video and now i feel like i can do it. i really needed to learn this since i have a test on it tomorrow. Thank You So Much for making this video! it helped me a lot! you are a really good teacher!
do you have any idea how obnoxious this comment sounds? do you have any idea how long i spend making these videos? you don't like this? DON'T WATCH IT. make your own. send me the link when you're done and i'll criticize your work.
being Indian is having a specific advantage..i.e., being able to solve such stuffs in seconds without any tutorial....! but, this explanation was adorable...! lots of love.❤️
Very good!. I'm 65 and just enrolled in a cyber-program for electronics. Lots of math, including powers of ten, which I don't remember learning in school 50+ years ago.
When you're adding or subtracting scientific notations with different exponents how do you know which notation to change in order to have the same exponent for both?
So when adding you can you either make the exponent bigger or smaller Ex=1.34 * 10 to the 14 +1.3 *10 to the12 So you can either make it bump it to the 12th power or the 14th power
at 4:51 you confused me, moving a decimal to the left is dividing, so wouldn't you want to multiply two times to get a bigger number to get to the -8 exponent? you would get a -12 exponent instead.
many thanks to you sir, im attending university and have been struggling with scientific notation and for some reason you have made me understand it when my professor has not been able to. THANK YOU THANK YOU THANK YOU
I’m in high school hopefully I remember
@Zachary Grubb Yes, here is a fun fact. Make sure you learn it in whatever grade you are in if you plan to go to University. By the way, I am now a University grad and have been working in my field for a few years now.
@Zachary Grubb OMG SAME. my teacher just gave me this and I'm stuck on subtraction one
SouFLoTV good job man I hope you’re successful! What is your field?
OMG im in 7th grade learning about this stuff
thanks so much for your kind comment! i'm always thrilled to hear that my videos are helpful!
Hey! How are you doing?
you have to change one of the exponents so that they are the same. i talk about how to do that in this video.
You have to change the exponent with the one that has least numbers of decimal places?
watch the video called "scientific notation: multiplication and division"
Where do u live?
Nice explanation 👍👍
Will do
Please make videos on class 12 chemistry also🙃
Thanks. You explain everything so well
Yes, it HAS to be only one number to the left of the decimal point. If you have more than one, for an answer like 45.3 x 10^3, it's not right, and you have to change it to 4.53 x 10^4.

Tyler DeWitt thank you l guess now l am really interested in maths
tyler why did you subtract 2.9785 and 0.0572??
oh sorry i thought it was addition LOL sorry
@DianaJimenezMUA nope, it doesn't make any difference which way you move the decimal point!
Thank you so much! During this whole "pandemic" thing I'm doing online school and my Physical Science teacher is not the greatest with technology. She's also been having difficulties with software so that doesn't help. However, this was a great help in getting my homework done so thank you!

At 5:22 shouldn’t the decimal move to the right instead since you want -10 go down to a -8
@cheese fries these exponents are negative so -10 is actually smaller than -8
@@destleefo8763 I actually had the same question..
,thanks 😊

Well since it's a negative number making the actual number itself smaller makes it less negative there for its bigger. The bigger the negative number is, the smaller it gets and vice versa
Damn you guys are smart af
You in your short videos teach more than my teacher in his whole class. Thanks so much your a big help and a lifesaver.
This explains it way better then my teacher. I think its because I can pause the video
I cannot stress highly enough the contribution you have made to students everywhere. Thanks ever so much for your wonderful teaching style. I have special needs and I am doing great now because of your videos. Humble and sincere thanks
you're so kind! and i love the wicked shoutout in your screename!
thanks, i had to learn this in Chemistry and i had no idea what my teacher was talking about. you made it so much easier to understand!
you saved me! thank you so much! The time and effort you put into making these videos is greatly appreciated and extremely helpful ;)
@awztukat you're completely good. it's just a negative number, nothing to worry about. you can write both positive and negative numbers using scientific notation.

so u in 12th grade now 🤔
YOU ARE MY SAVIOUR!! 2 HOURS OF CRYING, AND I FINALLY FOUND YOU!!!! THANK YOU SO MUCH YOU ARE A LIFESAVER!!!!
are you a teacher or what because you're a boss at explaining this, thanks so much you help me a lot!!
11years later, woah you're helping me with my science module
im just 6years old when you're discussing this!! im 17now
You should be my teacher! Your so good at explaining this!
you explained more in 7 minutes and 12 seconds, than my teacher in 2 weeks! thanks!
You're the best! You explained this concept so clearly. Liked the graphic for adding and subtracting exponents. This will help my son a lot! Thanks for sharing your gift.

can i just say, you saved my life. just started chemistry and makes about 0.00 sense you made it so simple!!!
FINALLY SOMETHING THAT MAKES SENSE!!!
I have a periodical exam next week and i find this really helpful
2019 anyone?
same. This helped me sooo much.
Helped me soooo much tmrw I have chemistry EXAM😭😭💔
Yep
Exam in 2 days, wish me luck
goodluck @@reezurk6135
Watching in 2019, despite my first thoughts based on appearance, this gentleman is quite a quality math teacher. Very well presented and explained.
Very nice video! But at 2:37, while one can increase or decrease the exponent while moving the decimal place in order for the same powers, would it actually matter of the choice of choosing which one to change?
No it doesn't matter which exponent you decide to make larger or smaller.
actually it does I tried that with his next subtraction problem and got two different answers
Jesus, it took me so long to get this concept and I'm almost failing my class but then there's this video i could've used for the past week.
Very nice.

i hope you didnt do what he did because if so you failed he did the moving of the decimal and changing of the exponents completely backwards
Actually I got it correct? What are you talking bout. But anyway thanx
i dont get with exponet to change?
boi ya dumb

Me. Lol
I've been watching your videos for a couple of years now and I just gotta say thank you for saving my grades
Awesome, teachers need to actually teach.
Thank you! I had to search so many videos in order to figure out how to deal with 2 different negative exponents. Amazing. Ty
Thank you so much! Schools don't teach well these days, sigh~
Reporting from the future, it still doesn't teach any better to this day either
Question.
When equalizing the exponents, should I make the decimal smaller and lower the bigger exponent, or should I make the other number bigger, and raise the lower one?

I was in class today and didn’t get much sleep the night before, so my brain wasn’t as active, so glad I found this.
I love you Tyler DeWitt you're the reason why I have an A+ in college gen chem
I almost cried watching this!! Thank you so much, you explained it so easily!
When you're adding or subtracting scientific notations with different exponents how do you know which notation to change in order to have the same exponent for both?
you change it to the bigger exponet
Thank you for this video it has really helped me in my Algebra class!! I love how you explained every step!
So when adding you can you either make the exponent bigger or smaller
Ex=1.34 * 10 to the 14 +1.3 *10 to the12
So you can either make it bump it to the 12th power or the 14th power
at 4:51 you confused me, moving a decimal to the left is dividing, so wouldn't you want to multiply two times to get a bigger number to get to the -8 exponent? you would get a -12 exponent instead.
