My professor should just play these videos in class on the overhead projector. I've learned more in 30 minutes from these videos than the 2 weeks I've been in class.
I have never loved math, but if you taught it to me, it just makes total sense and is not so imposing and / or overwhelming to me. Thanks for having this channel.
@yeedust watch my video on "scientific notation: multiplication and division." learn how to do that. then come back to this video and use significant figures in your calculation. your problem is no different from the ones i talk about in this lesson. use the significant figures rules to round.
This video helped phenomenally more than the one my AP chem teacher gave us to watch. within 15 seconds of watching, my main question had been answered, instead of waiting fifteen minutes for the yapper in the other video to get to the four points that didn't help with the assignment at all. Thank you for making this!
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.
I saw an hour long seminar on Significant Figures and didn't understand it all. I've seen your videos and have now got a clear understanding in about 30 minutes. Thank You!
Holy shit! I never thought it was this easy thank you. you saved me man. the way my teacher teaches is so monotone and boring you'd fall asleep but thank you, your a life saver
You are my hero this semester! I’m going to owe my career all to you. If I don’t pass chemistry this semester, my prerequisites for grad school would be at a stand still and I will never be able to ‘pass go’. Thank for making chemistry digestible and fun to learn. Plus you remind me of my ex, whom I adore, another plus. Just had to say thank you! Hope you are getting paid for this, otherwise i owe you, once I’m no longer a student ;) let you know if i pass this semester...tbc
You just got me to understand something that my teacher took like 2 weeks on and I still didn't understand. But you took like 8 minutes and I feel like a genius now! THANK YOU :D
you want there to be the same number of sig figs in both numbers because you're thinking about the rules for multiplication and division. but the rules are very different for addition and subtraction. in this case, you don't care about how many sig figs in the starting numbers, only where the decimal place is. if this confuses you, you should watch my video called "add and subtract with significant figures (1.6)"
I've been watching a lot of your chemistry videos and you really make chemistry easier. I'm a visual learner and your videos really help! Thank You! :)
I swear Tyler is going to help me pass my Chemistry class. Your videos are so helpful, I'm glad I found them on the second day of the semester. I was about to drop my class. The tutors that the school provides, are terrible. Thank you for helping me and many others. I have recommended your page to many students. You are the best!
i hate my physics teacher so much, she just makes us do a few problems and write down definition and that's it. Unfortunately she's also my math teacher :/ I'm glad i found you and other people that essentially saved me
i talk about this in "scientific notation and significant zeros (1.8)". the point is to show that those last two zeros are significant figures. but it's more complicated--check out the video!
no, the way i do it in the video is right. if this is confusing for you, watch my video called "add and subtract with significant figures," and message me if you still have questions.
Sir 😢😃U just saved me from the confusion Web of significant figures and scientific notation ,Everytime it used to skip from my brain .......Ur way of style just like I am not studying it feels me as I am playing with those topic that before Ur Your Videos Seems to teasing me......☺ Thankyou soo much sir.(in hindi: Dhanyvaad sir).🙇🙏
Thank you for this! This is my topic for my demo teaching and I'm really confused about it but when I watched your video, I already understood it in just 7 minutes. You saved my life brother! ✨
I have not used calculations for several years and decided to get my nurse practitioner (DNP) You provided a great review for my chem class. Thank you kindly!
Yeeessss! I’m a sophomore and this was in chapter 3 and I was like what???? And I even went to office hours, but I still didn’t get it. And then tomorrow I have a test on this and I was like I’m gonna fail I still don’t know how to do this, and then I found this dude and I am officially saved😇🙏🏼
because i'm adding here, and there are different rules for addition/subtraction than there are for multiplication/division. you want there to be 1 sig fig because those are the multiplication rules. but this is very important--make sure to learn the addition/subtraction rules and it will make sense: watch my video called "add and subtract with significant figures."
@Eywa355 no, i'm sorry, you're wrong. i think you might be confused because you're thinking about the rules for multiplication and division. addition and subtraction have a different set of rules, which i'm following here. let me know if this still doesn't make sense.
@MXMGamer good question. i did two videos that will help with this. the first is called "scientific notation: addition and subtraction." the second one is called "scientific notation: multiplication and division."
I just want to thank you so much!!! I'm doing online learning due to the virus and this has confused me so much, but you made the lightbulb go off!!! I hope you have an amazing life 😄
Hi, my name is Eva I'm in the 8th grade and my FSA is coming up, and the teacher told us that there will be a lot of scientific notation in there. I was so scared because I suck when it come to scientific notation (well at lease I use to) but then I found your video and that changed everything. Now I find myself to be good in scientific notation, now all I need to improve in is reflections and transformation. I just want to thank you so much for making these great videos that have helped me out so much.
Hey Tyler, I have one question about the final answer. Why are we ending up with 3 significant figures when the portion with (9.2x10^4) on has 2? I ended up with a final answer of 1.1x10^5 assuming only 2 significant figures were needed. Thanks for the help!
Tylor Ralph remember that when you add/subtract you take the least number of decimal places, not least number of sig figs. 9.2 has 1 decimal place, so after adding the numbers your answer should have 1 decimal place.
no. look at the numbers we start with : 2 sig figs in 2.0, and 4 sig figs in 8.330. we round the final answer to the smallest of these, so it should have 2 sig figs. why do you think there should be 3 sig figs in the final answer?
Thank you so much! As a 52 year old college student I appreciate the simplicity of the lecture. I have a chemistry test on Thursday and was worried...Glad to say, not anymore!
this was so helpful thank you! I was just wondering: I notice you use lot of paper in all of your videos. perhaps you could use a whiteboard or something to be more (sorry to be cliche) "Eco-friendly"? Thank you so much for your help!
Gayatri Devi Donepudi if the exponents are different, you have to move the decimal until one of the powers has the same exponent of the other one. Watch this guys videos on adding and subtracting in scientific notation, he explains it clearly
Who would click dis-like on such a wonderful eye opening video like this 😏... Thank man ur my hero 😂😂👊🏽 continue making them u made me past physis 97% in exam
I was crying because I thought I could never understand scientific notation and now it's making so much sense. Thank you so much. Chemistry hw here I go :'c
Tomorrow's my Physics exam...n ur vids r doing a great help to me !! Thanx buddy ! :D ..keep on posting such vids...bcz we ''the Gen-Y'' prefer RU-vid mre than our books !! :P
Thankyouthanksyouthankyou! I've watched almost every single one of your chemistry videos. And now I'm actually stoked to pass my chemistry exam tomorrow!
Two memory aids for adjusting the exponent of the 10. Case 1: up. "It was LEFT UP to me to clean the cat barf." (moving the decimal place to the left means increase, i.e., up, the exponent on the 10. Case 2: down. "The fire hall is right down the street from me." Moving the decimal point to the right means you decrease the value of the exponent on the 10.
your explanations on scientific notation really helped me master this information for my state exams. Would you be willing to do one on power functions as well?
I have this summer assignment I've been doing for AP Chemistry, and I'm supposed to show my work, but if it's as simple as ignoring the powered number, how would I show my work? Do you know the far more expansive version of solving problems that teachers always try to get across to their students, but fail to, because students are smart, and we find shortcuts? (: Haha. Please help to broaden my knowledge on this though. It seems incredibly easy, however, a problem not needing extra explanation should not be dealt with at this time. My brain is already swollen by all the information I've had to retain this summer.
Tyler, thanks for the help , but my chemistry teacher says that in science when its even you round down and odd you round up, is that correct, if it is you do that to 11.45 you would round to 11.4 , thank you
Some teachers do that, but it's not correct to use with science. Those rules were designed for accounting with money, and they're actually called the "bankers rules." Your teacher might wanna keep using the even/odd rounding rules, but maybe you could (politely!) tell your teacher that the even/odd thing is for accounting and bank statements, not for science.
+Tyler DeWitt Thank you for replying, my teacher would never take advice from any student mostly because he teaches for fun, getting paid from his patents in bio chemistry and mechanics, that he profusely brags about, and about his several doctorates in science, not to mention the daily mentions of his work done in " Baxter" ( I believe that that is how you spell it, as I saw it on the back of his shirt yesterday, AACC 88). This makes my job as a student very difficult, when i go online for extra help some things may be different than what he says, making chemistry harder than it could be. All teachers should be strictly held to same standards when teaching fundamental topics. Nonetheless, I really appreciate you spending your time to help students as myself, who need someone who explains in a way that is easily understood and could be rewind when you don't quite understand something. Keep up the great work man !! =)
OMG! You have helped me so much that I understand it better and now every time I hear the word mantissa I will think of you😂 Lol! Hope you see my comment but Thank You👏🏾
