Kids these days don't know how to use a calculator to do scientific notation. This lesson shows how to do so using several different commonly used models.
7 Years later and this video is still helping. I'm currently a college student taking a combination class of organic and biochemistry. It's been so long since I've had to use scientific notion i forgot how to use it. I was stressing out soooo much because I was doing it wrong. Thank you so much for posting this video!!!!
Doing that, your calculator will treat your scientific notation number like different numbers instead of grouping the numbers together unless you put paranthesis around them. I guess the [Exp] button is more reliable than [Shift]+[Log]
Hi, so if you are using the ti-30xa like in the video to the left of the = button is a button +→← on top of each other and -. Click that button before hitting the exponent number. Took me a bit and I found it. It's long over due answer, but hopefully it will help the next person.
Chem teacher here...I actually like the snarky tone...got your attention didn’t it! I actually needed it for the TI 30XS my daughter left behind...I always used the lazy TI-30Xa! 😂
TI and Casio actually had to relabel the [EXP] key as [*10^x] in the newer calculators, because they realized people didn't know what [EXP] stood for! The 'FAVORITE CALCULATOR' is a Casio fx-350TL or fx-350W or something?
Judging from his voice he is prolly and old man who is just unfamiliar with newer, faster calculators and loves to stick with his 'favorite' two line display calculator.
Thank u very much .... Today i have given a test and got 2 marks deducted cause of scientific notation ... 🙁 But Then i watched ur video and it helped me a lot, learning in online classes r really much though to understand but ur video Helped me a lot .... ❣️
Hard to say since I don't know what type of calculator you are using, but generally you can take a 5th root one of two ways. There should be a button somewhere that says "X(sqrt)y" that allows you to take an arbitrary root of a number. (In your case, X = 5 for fifth root). If that doesn't make sense, try this: raise the number you want to take the fifth root of to the 1/5 power like this: 32^(1/5)...if you're doing it right that argument should produce a result of 2.
Totally cool. I found 2 slightly different ways of entering it into my Android App calculator. The starting button is "x to an unknown power". You are a great math teacher, and really know your stuff. Thank you so much for the solution to this one. I knew it had to be the inverse in some way, but did not know how to enter it until you gave the expression.
In india calculator is not allowed in school for calculation 🤕 we have to do calculation on book or i can say have to do by own Thats why we dont have or use calci
as a old man who used (paper) logarithm tables, using exponents made sens in that context. on contemporary (2021) calculators you have to know about this stuff if you're dealing with very big/small numbers. but then again you should know the logarithm base ten and the arithmatic of powers. without that context i'd rather not learn Scientific Notation. anyway, with that precision, i could also use a slide rule without any disadvantages.
Not sure exactly what you are asking, but a positive exponent defines the place value, for example 10, 100, 1000 and so on. A negative exponent provides the decimal place: .1, .01, .001, and so on. Experiment with your calculator. That's why these scientific calculators are so helpful in actually understanding the number system. You can do a lot of practice without breaking your brain.
I like to imagine he recorded this video specifically to show it in class and rant at his students and prolly decided later to upload it to RUclips. No wonder he perfectly timed the response to kids who probably had an excuse of not having a calculator 😂
Not sure if this would help, but I found a video, at mark 1:19 that goes over it. ruclips.net/video/P0ktH5zfTaI/видео.html Basically, there is a sign on the calculator *at least mine* that looks like (-) , use that instead of minus sign. And you will need: ( ) those things :P (I needed to figure this out too, so hope it helps you as well!).
I dunno about TI's (never even seen one in my country 😂) but Casio generally has an 'Eng' button that changes large (or small) numbers into scientific notation.
Thank you so much.i am watching this before exam.after watching this i found the solution what i was looking for...thank you so much.love from bangladesh🇧🇩
I don't know what a child has ever done to you but if this is humor to you,I don't know how 843 people agree with this. Thank you,next bye bye. We don't need anymore mean people.
I hate to tell you this, but I tried to follow along with my calculator and only got as far at 3.07E. When I hit the "divide" key the E disappeared, and I have no idea how the enter the numbers after that. Could it be your kids don't know how to work the calculator because your explanation is very unclear? I would recommend doing it on one calculator at a time as opposed to three different ones all at the same time.
I eventually learned how to do it watching other videos. Rewatching your video, I found it quite informative. It seems your video is best for someone who sort of knows what they are doing already, as your video points up all the differences in the entry of scientific notation can lead to severe problems in the placement of the decimal. FWIW to get the result of your Math Department issued calculator, I have to use 1E-3 as the final entry. So it would be (3.07E4 / 6.2) x 1E-3, which results in 4.95~ which is curiously 4.95E3 or 4950 which is similar to your other answers.
Thank you for posting this 8 years ago, for people like me to find today.
Sir you helped me out so much but I'm still about to have a mental breakdown thanks tho
I guess it’s my turn to have a mental breakdown... especially when it’s virtual learning.
@@refinedqueen2260 yeah I get that
@@refinedqueen2260 Holy shit you guys feeling the same way? I have finance this sem and I have no clue how to ise a calculator. 😭
Facts
😂😂

❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
It’s very unfortunate, that there are teachers like you, that speak to people, students this way.
well then why u watching dumb cheeks
If ur so mad, then go watch something else and stop leaving ur hate 😊
I like the fact that this teacher complains at the first time then tells us to bring a
Calculator.
Like BRUH WTF
So much negative from the instructor. He starts out complaining ....
Stop whining, listen and learn.
Linda doesnt teach
Well it is frustrating when no one listens so stop complaining 😒
Agree, no need for that and it makes me unhappy when teachers are so negative like that
Bro this is the best instructor ever
Yea wth this guy says "I told you to bring a calculator, I've never heard of you man" my calc just broke
Hahahahah
then go and buy one, I told you not to watch my videos without a damn calculator
I'm not surprised no one listens to you with that tone. Good information here - just leave your attitude for after recording next time.
Agree
Cry in another place lol
Agreed
all of the two-line display casio models also have a second way of doing this: SHIFT LOG. it is displayed as a small "10". look for it at 2:30
+w0ttheh3ll Yes, but that's not the standard way of doing it. That's used for taking the antilogarithm.
I found that key, but it doesn't give me proper results. Perhaps I'm entering the wrong values, not sure.
Doing that, your calculator will treat your scientific notation number like different numbers instead of grouping the numbers together unless you put paranthesis around them. I guess the [Exp] button is more reliable than [Shift]+[Log]
Watching it after 9 years and it's still working dude keep it and thank u very much🥺❣️
May god bless you and your children for generations to come!!!!
+Jhonaton Castro can you give me the solution for fifth root
+Anita Pokhrel 5th root of what?
On the scientific calculator I want to calculate root *5 but didn't have any idea
by using calculator how to calculate the root 5th ??
Anita Pokhrel
I missed how to do the negative exponent on the TI. that’s the only thing I needed!
I was so confused cuz it was covered so I paused the vid but I still couldn’t find it XD
Ever figure it out? Cause I need help with that lmao 😳🤚

no need to be condescending. just show what you know and shut up.
addisbloom I was thinking the same thing smh
thank you i was about to comment to say what u just said lol
wesmoore16 stfu
Actually his technique telling you that you wont pay attention... has got your attention right?
Moon Diet ur just mad u don’t listen and when u try u get annoyed #payattention 😊
This teacher can spit bars with his attitude and I’m on his side cuz his attitude
10 years later, I'm glad you existed

The 'FAVORITE CALCULATOR' is a Casio fx-350TL or fx-350W or something?
Mayur I didn't know what it meant your comment just helped me figure that exp meant exponent haha thanks lol
@@mae8142 Lmao

Thank u very much .... Today i have given a test and got 2 marks deducted cause of scientific notation ... 🙁
But Then i watched ur video and it helped me a lot, learning in online classes r really much though to understand but ur video Helped me a lot .... ❣️
I'm not even a minute into this and I already wish you were my teacher lol.
About to throw my old Scientific Calculator until I saw this video. Thanks I finally know how to use my very old Casio fx-82SX
I am from India.Your teaching is very impressive.Iam wishing that you will do
Some more video s like this,which helps us in learning
I mean I understood what I wanted but I still feel attacked
I seriously cannot thank you enough!
I love thus instructer he literally is talking to me i dont have a calculater and i shuld i like you thank you
thankyou so much i have been trying to figure this out for an hour and a half and finally got it after watch your video.
Hey man, thank you. I was struggling with that since years. You saved my physics homework. Love ya.

Thats why we dont have or use calci
Must suck to be in India, no calculators?? That's harsh.
Lmao whats wrong with this man..... Its like his wife aint giving him......😉😂😂 he frustrated with his students
We ALL feel this frustration. As a teacher, this is dead accurate.
he just read this out loud in class
I could tell you were a high school teacher by the frustration in your voice haha
poor fella nobody listens to him.
as a old man who used (paper) logarithm tables, using exponents made sens in that context. on contemporary (2021) calculators you have to know about this stuff if you're dealing with very big/small numbers. but then again you should know the logarithm base ten and the arithmatic of powers. without that context i'd rather not learn Scientific Notation.
anyway, with that precision, i could also use a slide rule without any disadvantages.
(log(3.07)+4)-(log(6.2)-3)=6.694746686; 10^6.694746686=4951612,903. for precision i guess 4951000 is accurate enough given the values we started with.
thank you for this video. best teacher
How do you input a negative scientific notation to decimal notation on the Ti-84?
Not sure exactly what you are asking, but a positive exponent defines the place value, for example 10, 100, 1000 and so on. A negative exponent provides the decimal place: .1, .01, .001, and so on. Experiment with your calculator. That's why these scientific calculators are so helpful in actually understanding the number system. You can do a lot of practice without breaking your brain.
So when you're good at numbers,you don't have to worry about letters looking like aunt's nest
Thank you so much sir from this helpful information ☺️
Now here's a stand up guy that loves his job as a teacher!!!
Thank you Sir. ❤️ I do listen to you. My teacher say he won’t talk about it…
You have just saved my life. Thank you.
Preach!! Know you are not alone on this!
Jesus Christ thank you so much, I was super close to breaking down with semi-correct answers!
Thanks much was struggling with this ,it's so simple
Sir, you are awesome!! Thank you!!
Are you seriously pretending to scold some hypothetical viewer at 00:30? Just get on with it man.
I like to imagine he recorded this video specifically to show it in class and rant at his students and prolly decided later to upload it to RUclips. No wonder he perfectly timed the response to kids who probably had an excuse of not having a calculator 😂
This helped a lot for my Chemistry class, thank you!
thankyou so much you helped me in a most difficult thing
Also you talk the exact same way as my chemistry/physics teacher.
5:40 how do you make the exponent negative? (I have the TI-30Xa calculator)
Not sure if this would help, but I found a video, at mark 1:19 that goes over it. ruclips.net/video/P0ktH5zfTaI/видео.html

How to get lengthy number interms of 10 power
I dunno about TI's (never even seen one in my country 😂) but Casio generally has an 'Eng' button that changes large (or small) numbers into scientific notation.
at video point 5:57. How or what button did you press on the TI-30XA to enter -3?
Thank you sooo much this really helped me a lot, but I am still gonna have a mental breakdown but thank you so much
How to put power on number in casio like 8^5
The power button on a Casio looks like of these two things: 'X^y' button in older models or X^□ button on newer ones.
Thank you so much.i am watching this before exam.after watching this i found the solution what i was looking for...thank you so much.love from bangladesh🇧🇩
Which mode did were you on ti-30xs before you input the scientific notation
You are an amazing teacher👍,I really appreciate your videos. Your passion always inspires me. Keep it up!👏👏👏
I don't know what a child has ever done to you but if this is humor to you,I don't know how 843 people agree with this. Thank you,next bye bye. We don't need anymore mean people.
Hope it wasn't me. Sorry.
Thank you so much ❤️❤️
It really helped me alot
Thanks for the tutorial. It helped me a lot.
Bro, this is RUclips, lighten up a bit.
thank you, thank you, and THANK YOU!
Very informative 👏👏👍
Thank you sir this was really helpfull ♥️
This comment section didn’t pass the vibe check
Wow thanks you... great success
thxz i really need this
I'm from Bangladesh..
Thank you for that
You know what really grinds my gears 😂🤣
OMG thank you so much for this. I was stuck in scientific mode on that one calculator and couldnt figure out how finish typing my problem!
mahn its so realistic i feel like im bask in priso- i mean school
Thank you sir
It is useful for baignners
sir thank you very much you helped me a lot.
Bro i have the same calculater which is your favorite calculator 😮
Thank you boss.
thanks a lot sir, Godbless
Hw do u use d fx-83GT PLUS cal to solve for simultaneous equations
Don't know, sorry.
Thank you so much for this!!
Thanks sir... Take love
Good 🤠 thanks 😊 very nice 👌😊👍🇦🇿
what if you want to put a negative exponent?
Very nice
thanks for getting to the point quick
Dude in ur pic those r just 1$ bills ha gold digger 🤣
'Quickly'. For the first half of the video he was just ranting about his students not listening to him
Thank u good Sir!!!
Though you waste my time, i like your sarcasm 😂
I’m ducked and it’s only the second day. Welcome to physics honors
thank you BUT THE ATTITUDE

How do add 2 + 2 it very difficult
Ok which one of my current students said this?
Not me
Thanks for the vid! Much appreciated
Thanks sir
thanks a lot! helped me on my hw
Good jon
Where were u & RUclips & the general use of the Internet when i was at school? Huh? HUH?!
welldone sir allah save you
they're all listening now
It's not like they weren't ALREADY listening through THE NSA AND GEORGE SOROS c'mon popele READ A BOOK!!!!!1!1!111!!!!
Thank u so much sir i know now
That was very helpful thank you.
exactly what i needed. God bless.
very thanks y just saved me
does it matter if it is caps or na
Thank you so much
