i guess im asking the wrong place but does any of you know a method to log back into an Instagram account? I was stupid lost the password. I would love any help you can offer me
@Blake Bjorn Thanks so much for your reply. I found the site thru google and Im in the hacking process now. Looks like it's gonna take quite some time so I will reply here later with my results.
@Kinin4 great question! sig figging is the in-depth, jedi-master rules for rounding that you use if you're doing math for science questions. it's kind of like the rules for dressing well: plenty of people can put together some clothes that look nice (that's like regular rounding). but then you meet someone who's all like, "oh, if you're wearing that sort of a shirt, you really have to wear this color tie, etc. etc." that's like the sig fig rules--the special master rules for rounding in science.
You should be proud you have the ability to simplify the material and allow others who don't understand, to understand it. As always this video was very helpful.
Tyler, you are genius. The way you explain things makes me so excited as I understand chemistry from you better than any other chemistry site on you tube. I thank you so much as you clarified things that I have struggled to understand not only in significant figures but other chemistry lessons like redox reaction, polar and non-polar. you make my life much easier. Please don't give up!
@@ARMYALEX1869 the correct answer is 10 , because use the pemdas and after that follow the rules and use line to round up the result so therefore 1|3 ,,,,,,,so my answer is 10 because the next number after the line is 3 so automatically copy the first number which is 1 and ,,,why 0? because the next number is 3 ,, so my is answer 10 correct me if im wrong ;)))
@@ARMYALEX1869ik this is late but it’s because in multiplication rules, you’re limited to least amount of sig figs in the original problem. The lowest sig fig would be 100 (which has 1 means that you have to keep 1 sig fig at the end) which means that when you multiply it by 0.1 and get 10 then add the number with 3.1841, you can only keep the one sig fig. The number becomes 13.1841 and since you can only keep the 1, you have to keep the highest value (the 1 from the 10s place) and the 3 makes it round down, making it 10
yes- thank you so much. I've got a professor who (i can swear) only speaks Chinese (or at least it sounds like it) and I was getting SO frustrated in class earlier. At 27, i was embarrassed to keep asking questions, so these videos have been a great help. THANKS!!
Round to the thousanths. Those zeros in .100 count, because they come to the right of a decimal point. Watch my videos on significant zeros if a need a brush up on when a zero is significant and when it's not.
@Cartier736 the rules for addition and subtraction are completely different from those for multiplication and division. i think you're confused because you're trying to take the rules you learned for multiplication and division and using them for this. the method i describe in this video is the standard way to use sig figs for addition and subtraction, so if it makes sense and you can do it yourself, you're all set.
@roxxyroll3r i'm not adding 8+5, i'm adding 8.679+0.3+5.88, so of course i get more than 13, i get 14.859. just type those three numbers into your calculator and that's the answer you'll get, you won't get 13. then you take that answer (14.859) and round it to one decimal point, so you get 14.9. if you have questions about significant zeros, watch my videos on those topics.
Thank you Tyler! I'm using your videos to learn this stuff in Gen Chem in college. I forgot everything I knew about sig figs in high school. When we went through them in class today my Prof blew threw them and I was left confused. Then I found your videos. Now I can do them. Thank you! Take care!
@alfonsopeterman only when you're doing addition and subtraction. the rules are different for multiplication and division, and i've got videos for those, too.
So I did this all last year and didn't understand it. Then I went over it as review today still not understanding. Yet watching 1 minute of this video I got it perfect. Thank you so much!
I'm not Mr.De Witt...but I'm going to help you. The difference is....When you add/subtract you round your answer based on the number with the fewest decimal places. On the other hand, when you multiply/divide you round your answer based on the number with the fewest significant figures. I hope you understand how explain it....lol.
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.
This guy Is a genius he adds and subtracts from left to right that means he visualizes it in his head before he does his math great video really helped me for my test :)
@gabrielaw429 you can't add or subtract two units with different units, so you have to convert. however, you can't make meters (m) and square meters (m^2) match, because they measure different things: meters measures length and square meters measures area. so honestly, there is no correct way to do that problem. however, it's totally fine to multiply or divide numbers with different units.
CAME BACK TO SAY A MIGHTY THANK YOU FOR HELPING ME ATTAIN A GRADE OF 97% IN CHM- O9O. LISTEN, I AM 45 YRS OLD NEVER DID A DAY OF CHEMISTRY IN JAMAICA WHERE I ATTENDED ALL 9F MY SCHOOL YEARS. IF I CAN DO IT ANYONE CAN. THANKING YOU FOR YOU CLEAR AND INFORMATUONAL VIDEOS. I AM SO GRATEFULL FOR YOU.
@nosaj2011 yeah, some textbooks have that rule. find out if your teacher wants you to do that, and if they do, you should do it that way. the reason i don't teach that is because it's wrong, pure and simple. that method of rounding is known as the "banker's rule," and is used for accounting, you know, like calculating money in bank accounts, NOT for doing science. i have no idea when and why people started using it for scientific calculations, but there's no reason to use it for science.
THis is so awesome! I am a novice to Chemistry, but you have taught me well in a few minutes. I thank God for people like you who makes learning so intriging.
@roxxyroll3r yes, you keep both the 2 decimal places. don't worry about any numbers that are to the LEFT of the significant digits (those two zeros are to the LEFT of 5, which is the significant digit). you only worry about where the significant figure (the five) is, and that's in the second decimal place from the right. does that make sense?
no, it doesn't. to better understand this, check out my video called "what's the point of significant figures?" also, if you watch my videos about significant figures and zero, that might be helpful too.
This video was awesome, my science teacher was talking about the place value e.g tenth, hundredth... I didn't have a clue.. I now know how to add and subtract! Thank you!
I was struggling with this. Adding and ensuring the final answer has the same number of decimal places as the measurement with the least decimal places. Thank you. I got this question wrong on a quiz, but it feels great to no longer feel tormented by one wrong answer. Lolz. Now I’ll conquer class participation and the exam.
So incredibly thankful for your videos! You make understanding these concepts so truly simple. Plus, you have a very easy-going personality, which helps bolster my confidence.
Thank you, thank you, thank you! That's 3 significant thank yous. Your videos on significant figures helped my daughter greatly and helped me to help her.
@Lauren5723 i certainly don't want to start a rumble here, but you're absolutely right, and your teacher's wrong. when rounding, you look ONLY at the number just to right: in this case it's a 4, so you keep it 90.2. the fact there's a 5 two spaces away makes no difference whatsoever. consult another website if you want some more proof (type "how to round" into google), but you're correctly following the rules.
I have Honors chem. and it's not really hard for me !, its just the way the teacher explains it that confuses me , but thanks to you, chem. is becoming like a piece of cake , thank you so much :D
Dude thank you so much, my teacher explained this horribly and the other video I tried made me even more confused. I was about to end up in tears. After watching about a minute of this I already understood, and it’s so easy now. Thank you :)
I did not really understand adding and Subtracting sig figs because we only had 1 day to learn and practice it! So thank you SO much for this video! :)
4.34: you round up 14.85 to 14.9 but according to rule if the rightmost digit to be removed is 5 then preceding number is not changed if it is an even number , it is increased by 1 if it is an odd number.
I'v watched so many of your videos, and I ABSOLUTELY LOVE THEM!! They've been a huge help for my teaching master's program. All your videos are so simple and straight forward. I teach science and I wish I could tach as well as you do. Thank you SO MUCH for sharing these! :)
Never seen so far someone who has a passion like yours to teach others...I mean the way you did this is super fantastic...awesome Tyler.. can't help subscribing and appreciating you...above all...your lectures are free....unbelievable...but..that's true..god bless you...
I was utterly confused by my homework on significant figures; I thought I would never understand how to add or subtract them and the rules were too complicated. What i failed to learn was explained to me in 2 and a half minutes. Thank you for this 😊
@jejuliz I'm taking chem and bio for the first time in ten years, and in class I feel like fish out of water. But tedwitt451's videos help a great deal. We're on the same boat, so don't feel too bad. Good luck with your studies.
I can't begin to tell you how many times I have had lessons from math books about significant numbers and couldn't figure them out. I believe I now understand.
You are absolutely AMAZING. My teacher tried to explain this to me yesterday for a whole hour and I couldn't get it. Your video took less than 5 minutes now I completely understand. You are the Awesome!!!!!!!!
you're awsome. just straight up! your explanations are much easier to understand. I wish you were my chemistry teacher! thank you for taking the time to make these videos :) you are a lifesaver to my brain :)

@Marshall Damon Glad I could help :D
Thank you for existing! You're like, way better than my Science teacher! ^_^
Agreed!
I agree, my science teacher takes a while to explane things, and by the end you have forgotten what the question was, or he explaines it weirdly
+Kagamine Rin I agree.
Mine doesn't teach just makes us work out of the book!

14.859 should be rounded off to 14.8 since 8 is already even explain
@@pcm8492 Thank you. I just was curious about that. I had to review.

Same here. I didn’t understand what to do with the problems with whole numbers and now i do.
Literally learned way more with him than I did with my teacher 🤭
If they both have the same number of decimal places, then you don't have to worry about doing any rounding! Just keep the answer like it is.

I LOVE YOU FOR MAKING THIS VIDEO!!! i got a new chem teacher and she doesn't explain anything.. thank god for TH-cam!
You made this 9 years ago and it’s still helpful
he explained it 10x better than my teacher w/ a phd for this stuff, he made it so easy to understand

did he just say oof
he was ahead of his time
Yes
andrea yeah fr😂😂😂😂
Mine craft

Thanks man i failed my last sig fig quiz so i looked this up for help, now i got a grasp on it :)
4:10
But because 8 is an even number so shouldnt the rounded off number be 14.8?
Yes u r correct
I can't begin to tell you how many times I have had lessons from math books about significant numbers and couldn't figure them out. I believe I now understand.
YOU ARE AWESOME....I watched all your gas laws lesson and now im feeling confident about my exam tomorrow!!!! THANK YOU!!!
You are absolutely AMAZING. My teacher tried to explain this to me yesterday for a whole hour and I couldn't get it. Your video took less than 5 minutes now I completely understand. You are the Awesome!!!!!!!!
your videos help me alot with my hw. thank you man. btw I think your subtraction on 3:11 is wrong. i think it suppose to be 40.34
This guy saved my life. I would have had a hell of a time in chemistry
I'm legit watching this because I'm bored ngl I'm loving it because he's so patient while explaining ✨
@MrJessejconrad i answer this in my video called "scientific notation and significant figures (1.7)"
Thank you so much! I learned more from this video than from the worksheets and boring notes my teacher writes on the chalk board!! :)
Omg you are seriously a life saver
Thank you sooo much... this was so helpful, WAY better than it explains in my textbook.
This is fantastic! You make Chemistry so much easier to learn. I truly value the help. Thank you!
Should it be 14.8 because of rounding 5 rules?
