It is not a difference of your way or my way, you are seeing the power of round off error! If the entire expression is typed in a computer at once you get your answer. If you work out the problem in steps as I did, even going out quite a larger number of decimals, you will have some round off error. The high the powers, the more careful you need to be about rounding:) Thanks for watching and the comment!!!
And THANKS Nick for saying so!...Thank you too for liking and subscribing...I appreciate the support and hope if you continue to like what you learn you will share my channel with others at school:D
There are some who should retire...but there are a lot of us who still love what we do and that's why we do things like this...to help others who make the effort to help themselves:) Thanks for being one of those!!
You are SO welcome! It is generally the motivated students that seek out extra help and I'm glad my channel is becoming one they choose to watch and learn from. I will be starting my 3rd year growing my RUclips channel soon and we hope someday to be one of the favorite math channel to watch..."If you can dream it you can do it"
I'm glad to hear that I am your go-to RUclips teacher and my videos are helping you through your math course after all these years...good luck and CONGRATS to you for taking on the continuation of your education!
+Austin Copeland thanks for choosing my channel to study with! Please help us grow by liking, subbing, supporting the ads and sharing this channel with others:D
I am so honored and excited about your comment:):):) I hope you do great in your PreCalc class and I am glad I can help ease the toture...haha. Even being compared to the long time RUclips video producers you mentions is high praise. THANK YOU THANK YOU THANK YOU! Please help me by spreading the word about my math channel to anyone else that could find them helpful.
I hope my videos will be the additional help you need to ace those finals!! Thank you for the show of support and subscribing:) Please share with your fellow students as well...spread the word:D...thanks.
Thank you for the kind words:) I am very glad you like the way I teach. I hope that my style of teaching and how I record my videos help to develop a nice viewership/fan base for my math channel. I really love to hear you are helping others based on what you learned from my videos too! Sorry you tried to type your comments twice. I am an active full time teaching, so I like to approve what is posted to avoid any issues with my job or students.
That's awesome! Thank you for watching more of my videos and making a playlist of them. I really appreciate the support, my channel growth is dependent on viewers like you sharing with others:)...thanks again!
It is so awesome that I get to try and help people all over the world with a small camera and a computer. I am very glad you liked my video. Thanks for watching:) I hope you do well in your studies.
THANK YOU:) I am glad I could help. Making RUclips videos wasn't even my idea. I student said something about doing this last year. I wish I had started making these years ago. I wish you great success in your classes!
Now that you have subscribed you will be able to pull up my channel and watch a new video every time you feel the need to be taught a new lesson:)...and if you share with all your friends and classmates you could start a study group together to watch my videos, and then I would be like your private teacher! Thanks for watching and supporting by subscribing....what are you waiting for?...go start sharing...LOL :D
eh..emm...did not skim that far into the video...sorry. In the last example the variable is still in the exponent. You can solve the equation by applying the log of any base you like to both sides, common log base 10...Ln...log base 2 if you want, your final answer will be the same excluding round off error. I had just used the natural log on the previous question so I used it again. A time stamp in your question will ensure I answer your question correctly:) Thanks for watching.
I've been out of high school for 13 years and I'm now having to upgrade my pre calc as I never took it when I was a student. My teacher rushes through all the units and I'm so great up that I can count on your videos to give me that extra bit of clarity on some of these complex concepts. Thanks a lot your my go to back up when I'm lost and you never disappoint. Keep up the good work.
Thanks for studying and appreciating Catherine! Don't forget to sub and share this free study resource with your teacher so ALL future students might benefit like you did...BAM!!!
You're welcome...and thank you for "liking" my videos, I appreciate the support and your viewership! (sorry for the delay but I have my channel set up to "approve" all comments before posting)
THANKS for liking and subscribing…that's a great start! Keep watching and sharing my channel with all your friends and classmates and continue to help my channel groW to its full potential!!!
Glad to see that the life-ring continues to be beneficial:)) So happy to hear that my video helped you so much...the info is out there, you just have to swim through the junk! Hope you will keep watching my channel and be sure to share with your friends if I've helped. Thanks:D
thanks, and thank you too for subscribing...my channel growth happens through my subscribers and channel support:) Please spread the word and share my channel with your friends:D
You're welcome...and THANKS for supporting by liking and subscribing. (Sorry for the reply delay, I have my channel set to approve all comments to keep it viewable for ALL audiences:)
And THANK YOU sir...I hope to see your "superpowazz" kick into overload after watching and learning from my videos:)) Please be sure to subscribe then you will stay current of all my new postings....thanks again for watching and supporting:)
So... I am a student at Oklahoma State University and I must say, 9 times out of ten I come to your video lectures before I ever talk to my professor. You answer everything I need to know and keep it entertaining, well, as much as math can be I suppose. Thank you so much though!!! You should open an account for tips! I would love to pay you some for what you do! I know teaching is not the greatest of pay and someone like you deserves it!!!! Honestly!!! Thank you again!!!!!
Your answer is more correct than mine. I calculated my work in small steps to go over the order of operations in this problem and ended up with a bit too much round off error. Thank you for watching and commenting. Glad to see you are working the problems, that is the best way to learn:)
THANK YOU:):):) I hope you do great in the math classes you have left in college. I tend to over explain as I teach and without the time constraints of a bell ringing....sometimes I go way overboard!!!
Decay is when your base is between 0 and 1 and since you are talking about half life your base is 1/2 and growth is a base >1. So you have 16(.5)^#decay periods. Since your half life is 3.8 days you lose half in that number of days if you had a time period of 7.6 days you would go through 2 decay periods or 7.6/3.8=2. I hope this helps:)
WOW...guess it was your lucky day huh?!...not only did you find T but you found (T)arrou's Chalk Talk to teach you...hahahahah:) Really, thank you for the comment and I'm glad you won't be bald for halloween!...(more bad humor, can't help myself sometimes) Thanks for watching and supporting:D
I hate to hear you feel that way about your teacher...but I am glad you found my videos and liked them:) Anyone self-motivated to find outside help on their own will always succeed. Keep up the good work.
Uhhhhh... Thanks:) I think I will just keep working on my videos so you can get the extra help when you need it! I am really glad you are finding them so helpful.
You are so welcome! That's what I'm here for:) I hope you will continue to look to my channel for additional help and if you like it please support and subscribe and share the channel with others:D
Interest rates are almost always based on a year, especially money. So when your money compounds monthly, you need to adjust the yearly percentage rate into what you are making per month so you have 10000(1+.07/12). The exponent is basically the total number of growth periods and there is 2(12) or 24 growth periods in 2 years.
First and foremost you have WOWED me with your compliments!...and you hit all the points. *To make math fun while learning, *To teach with explanation, and *To help students feel more confident with their work! I just made my new banner page, and because of multiple requests, added a "tip the teacher" link at the bottom right of the banner...does this mean that you can't see it where I placed it or you were not on my homepage? You're feedback would be appreciated.
You take the ln(2) and then divide by .05. I did not enter the entire expression into my calculator at once and rounded off a bit too much. Ln(2)/.05 is approximately 13.863
Thank you SO much! I was having such trouble with this. Must be good to see that your teachings are still being implemented by students willing to learn. Keep up the awesome work and thanks again!
Thank you...always nice to hear MATH and FUN in the same sentence! Thank you for supporting my channel and if you like it be sure to share with your friends:))
You usually need logarithms to solve an equation when the variable is in the exponent. Since the base of the exponent is e using log base e, or the natural log (ln), saves me a step because it quickly cancels with the base e.
EXCELLENT...Spent almost a day on a problem like this, my teachers method of solving it was too complex, dis s a much simplified and easy method...Thanks so much
Thank you...I can never hear comments like yours too many times!!! I really appreciate you taking the time to send such a heartfelt comment:)) It's people like you that keep me motivated to continue my job...teaching can feel thankless at times but you reenforce the reason why I choose this as my profession. Keep watching and be sure to share my channel with your friends.
Thank you for seeking out extra help and choosing me to be your RUclips math teacher! Now that you have subscribed I too look forward to you continuing your math education with the help of Tarrou's Chalk Talk:D I hope you're feeling better now too =)
Professor RobBob ,thank you for explaining and solving Compound Interest Problems in Precalculus/College Algebra. Once again, this topic is well known throughout Mathematics and the Invesment/Bank World.
That sounds like a very good idea. This upcoming school year will by my second time through with my new math channel. I definitely need to fill in some gaps and redo a few videos:)
Appreciate the videos! This is really something I wish I would have paid more attention to at a younger age. To anyone here in the younger crowd pay attention to this! It's probably the most important things you will learn in high school. I skimmed through in school to pass this class and I regret every minute of it. Now I'm here at 30 relearning what I'm kicking myself for not nailing down to begin with. Don't be me!
And I appreciate you sharing the "words of wisdom" John Flynn ! I think after a certain age we all wish there was something we had done differently but admitting our mistakes and sharing our life lessons is one way to "pay it forward" if one takes the opportunity to use them:) Thanks for watching and subbing and best of luck on your new math journey...hope my videos continue to be beneficial for you:)
I like your energy I wish teachers would know and understand that teaching styles influence comprehension as well, keep it up, I have never done compound math’s but I learned a lot from your video and yesterday I though a math’s student one thing or two about compound, I am going to teach her once more today from the video, this is also my first youtube interaction from SOUTH Africa
Sir, may I suggest you start making some word problems with logs. I think application to real world activities really deepens the concept. Thanks and appreciate your hard work!
oh my goodness, I have been scrounging videos for this...and then I come across your video...I cannot tell you how clear you made everything! *subscribe!
BAM!:))...One more to add to my captive audience, thank you! And remember, as a subscriber you will be notified of all my latest downloads. Spread the word if continue to find my channel helpful...thanks.
+MsPopperson THANKS for watching and subbing! Please continue to share my channel with all your friends and tell them to sub and do the same to help the free educational channels they find helpful:D
Your energy and excitement make me laugh. :) I think MCC might owe you some money since I'm using your videos a lot as I'm taking an online algebra course. Feel free to send them your bill (but don't tell them I said so...I still need credits). LOL
Thanks for choosing my channel to learn from, like and sub! In leu of a bill maybe you could just tell MCC to share my channel as a free resource tool for their students:) Then you get all the CREDITs...lol:)
great video!!!! ive been absemt a lot the last few weeks. sick. and all your videos really helped me catch up. thanks and I look forward to future videos .
You're welcome DeadWolf and thanks for choosing Tarrou's Chalk Talk to learn from:) I hope you'll SUBSCRIBE and return whenever you need FREE math help:)
haha...that is embarrassing. I always say I teach math and not english but that is just bad! I can't always talk, think, and write at the same time. Thank you very much for watching and correcting me:)
Thanks for making this video. I just wanted to point out something out, if you type the entire first equation into a scientific calculator using the fraction (.07/12) you get $40387.39... Your rounding of the decimal slightly skews the answer. Probably worth noting in the video. But thanks for making me think!
I have a video teaching my writing too...lol Thanks for watching and learning Kasey A please like, SUBSCRIBE, support the ads and share my channel with others if you continue to find it helpful because that's how I groW and help more students learn "what they were doing wrong"!
at 14:18 I believe you did a rounding error. the answer is 13.86 =t doesn't that round up to 13.9. I don't think it matters all that much but I figured I would say something anyway. I am also super grateful for theses videos.
@faaavalon You are very welcome. I am glad you found my video so helpful:):):) Thanks for the kind words.

How about 2019?
Almost end of 2020 here!

I am not sure where in the video you are referring to...other than there is 12 months in a year.?
You are absolutely correct in that they are not equal. I was inconsistent with my rounding off in this video. My apologies.
You are very welcome. I wish all my students would be willing to spend a day trying to solve their math problems!
Thank you SO much! I was having such trouble with this. Must be good to see that your teachings are still being implemented by students willing to learn. Keep up the awesome work and thanks again!

This video is from 2011 and I'm watching in 2016 and this was soooo much more helpful than my teacher could ever teach :))
+Giselle Gomez thanks for watching...the only thing that's changed since 2011 is the color of my hair...lol
The best and most clear math from youtube. Great video and i was able to learn so fast

I love what I do and my mission is to try to "Make Math FUN!" while learning...so thank you for watching!
That is compound interest compounded weekly, so p=1000,r=.03,and n=52.
I love your handwriting... you're so good at writing on chalkboards! Haha, really great video too
THANKS...19 years of experience makes it easy:)
I like your energy I wish teachers would know and understand that teaching styles influence comprehension as well, keep it up, I have never done compound math’s but I learned a lot from your video and yesterday I though a math’s student one thing or two about compound, I am going to teach her once more today from the video, this is also my first youtube interaction from SOUTH Africa
Math really makes me anxious and depressed... but your videos really made it more enjoyable for me. Thank-you.
You're welcome...and THANKS for choosing Tarrou's Chalk Talk to help teach you math and learn to enjoy it:) Also, thanks for subbing!
Wrap 13/9 in parenthesis and the exponent of 1/540 in parenthesis and I think you will be fine. 180 compoundings per year?
Thank you so very much! This was by far the most helpful video that I found for compound interest.
Sir, may I suggest you start making some word problems with logs. I think application to real world activities really deepens the concept. Thanks and appreciate your hard work!
@xaqua93x I didn't mean to remove this!!!
oh my goodness, I have been scrounging videos for this...and then I come across your video...I cannot tell you how clear you made everything! *subscribe!
Nice step by step this really recommended for the beginners
mano esko thanks for watching!
My round off error was not on purpose and it has caused a couple of questions, but it shows how important what decimal you round to is:)
Because I worked the equation in steps, there is round off error which you don't get when you type the equation in all at once.
*Your teaching makes me feel so confident in mathematics/finance!! Thank you! P.S. audio sounds great to me.
BAM!:))...One more to add to my captive audience, thank you!
And remember, as a subscriber you will be notified of all my latest downloads. Spread the word if continue to find my channel helpful...thanks.
Thank you so much. I really needed this for my test. I think my grade will go up now. Subbing to you. You're awesome bro!
Do you want to find your monthly interest rate if you know the yearly rate the bank advertises?
@delenabangel You are welcome:) ...and thanks
Subscribed. Your enthusiasm is so perfect

2017???
great video!!!! ive been absemt a lot the last few weeks. sick. and all your videos really helped me catch up. thanks and I look forward to future videos .
It is that simple!! :D
Thank you! You saved me from going into an exam without understanding this. :)
You're welcome DeadWolf and thanks for choosing Tarrou's Chalk Talk to learn from:)
I hope you'll SUBSCRIBE and return whenever you need FREE math help:)
You need to wrap you exponent in parenthesis. You are raising 1.67 by a power of 1 and then dividing by 120, not raising 1.67 by a power of (1/120)
haha...that is embarrassing. I always say I teach math and not english but that is just bad! I can't always talk, think, and write at the same time. Thank you very much for watching and correcting me:)
Did you figure out the answers? Sorry I just saw your question, though I don't know how to answer these.
Thanks for making this video. I just wanted to point out something out, if you type the entire first equation into a scientific calculator using the fraction (.07/12) you get $40387.39... Your rounding of the decimal slightly skews the answer. Probably worth noting in the video. But thanks for making me think!
Your students = Lucky kids my friend.
Thanks for the lesson and the enthusiasm!
I love your videos! You are a life saver!!! So if continuous compound interest were to triple, would we do what you did in the second to last example?
Excellent
Thanks!
Don't forget to sub and share too:D
This video is a life-saver
BAM!!!
Thanks for watching..please sub and share too:D

at 14:18 I believe you did a rounding error. the answer is 13.86 =t doesn't that round up to 13.9. I don't think it matters all that much but I figured I would say something anyway. I am also super grateful for theses videos.
Hey Prof Rob Bob,
Thanks for the video. Out of curiosity, why does the exponent drop when you cancel out the e? Is there a rule for why you do that?
What would be the raw formula to determine "r"? I am trying to implement such a formula into a computer program. Thanks for your time.
@delenabangel 9300=5100(1+.01/4)^(4t).....1.824=1.0025^(4t).....ln1.824=4t*ln(1.0025)....ln(1.824)/(4*ln(1.0025)=60.178 years.
My teacher makes me feel dumb. Your videos make me feel smart. Therefore, I chose to learn from you.
