Mr. Tarrou, the single greatest math teacher of the 21st century.
THANK YOU for the compliment Stephen...don't forget to like, subscribe and share all this greatness with your friends, classmates and teacher too:D
Just wanted to let you know, I have told exactly ten friends about your awesome channel over the course of this last week. It is a joy to spread the good news that math can be learned in such an awesome and enjoyable way!
Look at you...now you're even spreading the word after that awesome comment!!! (didn't realize you had already made a comment till now:) Don't forget to remind them all to sub too..the goal is still a million subscribers and that GOLD play button...lol, we'll both be retired before that happens:(
Thank you:):):) I have been teaching for 17 years. These videos are exactly how I teach...only I don't stop and answer questions. I feel like I have to be even more organized making videos compared to live teaching. If I make a mistake, there is no one in the room to catch it! I am glad you like them so much. It is very cool to now be teaching the world as well as my own students! I am very excited about my new UA-cam project. Thank you again very much!!! Spread the word \:D/
CONGRATULATIONS Anthony! That's a number you should be proud of and a number your UA-cam teacher loves to hear about:D Thanks for sharing and keep watching and learning so you keep up those great grades!
THANK YOU from Florida for watching my videos and learning more than math:) I am very pleased that you have chosen to watch to learn two things from my channel...this is the sign of a motivated student!
LOL...lol...and I'm still laughing! That is by far my best BAM comment to date!
Thanks for taking the time to share your experience and gratitude with me. I appreciate your support and hope you continue to choose Tarrou's Chalk Talk as your go-to math teacher...now BAM!!!...go pass that final:D
omg youre such a great teacher... my teacher is so GOTDAM IMPATIENT !! she talks so fast and doesnt go through things clearly... and when test day comes... i dont know crap!! ive learned more in 10 minutes here than what i have learned in my class for 2 hours! god.. please you should be my teacher
Mr. Tarrou, I just want to say that while historically I've hated math and constantly questioned its usefulness, you make me glad it exists. To see someone able to take concepts and human constructions and convey them with such clarity and enthusiasm, even able to give me larger connections that I've never before realized...I believe that makes all the difference, and thank you for that!
You're welcome Zac, and THANK YOU! Students and comments like yours are why I love teaching:) I also appreciate that you took the time to share such a complimentary comment. It's a lot harder to groW an educational channel since there is not much about math to go viral but it will continue to be my dream to someday have an "M" next to my subscriber count, thanks for adding one more towards my dream by liking and subscribing:)
You're welcome...glad my teaching style worked for you and I hope you will continue to watch more of my videos!
I must say, you should get an award for doing all of these videos... Sadly I believe math is one of the most under taught fields in school.. I greatly appreciate your videos! No matter what anyone else says to you, you have definitely impacted many many lives :) I guess that's why all teachers become teachers! my mom teaches, that's what she says at least ha.
+Techy2012 she's right...it certainly is not for the money:) One of my favorite quotes is: "choose a job you love and you will never have to work a day in your life" I find that most teachers teach because they love to teach and when you make a difference in that one students life, well thats something money just can't buy!!!
Thanks for watching and sharing your appreciation and thank your mother from one teacher to another:)
The best feeling is the feeling of understanding. Thank you for delivering.
And thank you for taking the time to learn...BAM!!!
Don't forget to sub and share this channel with everyone:D
Great idea...I had a viewer who put a weekly study group together, they would all watch a video and then work out problems together. Work always seem to be more fun when you have others around:) The internet can be a wonderful place to learn from!
Wow, another great video. You really are excellent at quickly explaining math and making it seem logical, within the first 8 minutes I went from being completely stressed and confused about expanding logarithms to being completely comfortable with it. Keep up the great work, I wish you success!
THANKS for watching and learning from #ProfRobBob and for the good wishes!
Please help us groW by liking, subbing and sharing this channel and your learning experience with others and reminding them to do the same:D
I'm pleased you found my channel and that it was helpful to you. Don't stop now...there are plenty more videos to watch:))
You're welcome. I'm glad I could help you understand logarithms and I hope you keep my channel handy the next time you have the desire to learn more math!
I passed calculus back in December thanks to your clarifying videos Professor RobBob. Thank you sir for posting this on UA-cam.
CONGRATULATIONS on a job well done Matt A !
You're welcome and thanks for sharing that accomplishment and choosing #ProfRobBob to help...BAM!!!
I am really happy I could help!!! Thank you for the kind words:)
Well, what do you know... it never occurred to my stupid college textbook to tell me that the properties of logs were analogous to the exponent operation rules I learned in elementary Algebra. It makes perfect sense now to see why these logs expand the way they do: you add exponents when you multiply, subtract them when you divide and multiply them when raised to a power, cause logs are really exponents after all. Those first 5 minutes were enlightening. Thank you so very much! You are the best!
WOW Rafael Montecristo you learned that all in 5 minutes when my own students sometimes can't learn it in a week...lol
...and you are one of my best YT students:)
You are *REALLY* Welcome! Thanks for being a returning viewer. And for continuing to send comments...they are always so positive:)
Thank you very much for all these explanations. Am actually studying at the university and i have never done maths at school,am learning a lot with you,and the fact is that i can't attain all my lectures on saturday as i have to work and study at the same time so your are my online Tutor!!!
Your videos are truly superb! You explain everything so well, and let me compliment you on the fact that your videos seem so well organized and planned out. I can't even tell you how many math videos I have clicked on only to have my time wasted by someone who spends 2 minutes drawing a graph or trying to think of an example problem!
YEAAAAA!...that's the point of these videos, and you just got it!! Believe it or not, it makes us teachers jobs much easier when you get it too! Thank you for subscribing, for "liking" and for taking the time to seek these videos out and learn, you make me proud!:D
Yipppeeeeee! Another believer!
My goal is to "Make Math FUN!" and without knowing that, you made this comment...that puts a giant smile on my face:D...thanks.
I always watch your videos before I got to my lectures. It helps keep my head clear while listening in class. You have a gift for explaining math very well. Thanks for sharing it with us! I've liked and subscribed!
You are so welcome!!!!!!! Thanks for showing your support and subscribing...my channel grows through the support of my subscribers spreading the word...keep watching and sharing and sending these nice comments:)
What's that you say?...did I just read the words MATH and FUN in the same sentence?! My teaching style is done in a way to show that math can be fun while learning! Whooohooo...sounds like I've converted another viewer:) And congrats on that A+...more words this teacher can never hear enough of:D
I just want to say thank your for your time!! REALLY!! This helped me greatly to understand my math homework! Since I was all over the place in class and my current professor does not really teach!
And THANK YOU ROTWEILAS LAGATA for choosing, liking, subbing and taking the time to find additional help on UA-cam and not just giving up:)
Sounds like you need to share my channel with the rest of your class too...BAM!!!
amazinggg!!! I am a soon to be pre-calc student, we did not do any logarithims in Algebra 2, however, I always had this desire to learn them. I have tried learning about these several times but failed because they just seemed so confusing. But, your way of running through the problems really helped me understand. Thank you very much!
You're welcome...I like to see that you are still watching more of my videos:) (I always remember your name when I see it because it reminds me of my wife...her nickname is Queenie because she's know as the "queen of everything" and I'm the "king of what's left"...lol)
Thanks for choosing my channel to learn from and I hope you will like, subscribe and share with your friends to show your continued support:)...it's important to the growth of my channel:) THANKS again!
Thank You! I'm in my 60's and self teaching. Your algebra 2 videos are the best. Your presentations are friendly, informative and fun.
No...thank you for proving to everyone that it is NEVER too late to learn!
I'm honored you choose my channel to learn from and subscribe to and hope you continue to enjoy your learning experience from Tarrou's Chalk Talk!
@ticeazure That is awesome. I'm glad I could help. I hope you did well on your test!
Hey Prof Rob, I was just going to say your videos are fantastic and extremely helpful. They have helped me so much with my online class and they have actually saved me so much time. Thank you for taking the time to do them and making the world hate math less.
THANK YOU Emi 〈3 for taking the time to thank the teacher and for choosing #ProfRobBob to watch, learn, like and subscribe to! Glad they helped so much.
I love teaching and appreciate the opportunity to share my passion with the world thru UA-cam!...and if I'm also helping students to "hate math less"...well, that just makes it that much better...BAM!!!
Totally faked properties of logarithms in high school. I did so much relying on memory yet never understanding... You are answering many questions that I have carried around with me since the 70’s!
Thank you so much!
You are VERY welcome! ...and thanks for putting a smile on my face:)
Proof once again...you CAN teach an old dog new tricks...lol
(and not implying your old either:)
Prof Rob thank you very much for taking an initiative to support us. I don't see myself failing logs and on now.
You're welcome and thanks you Lungisa Gobinamba for taking the initiative to study and choose #ProfRobBob
You'll find that most of my videos are taught in full lessons and all are key-worded so you can find what you are looking for with ease:) It's hard to work and go to school at the same time...I did the same through most of my college career as well. Keep up with your motivated learning habits and you will sail right through!
I am honored to be your online tutor Wendy, and I appreciate your support by watching, liking & subscribing!
You make me smile so much at maths and laugh so much that people think I'm lying when they see me sat here "studying". You're great, happy belated pie day
Thanks for liking, studying and subbing to my channel...and I'm happy to hear that you are finding it so entertaining too!
I hope when those people are seeing you smile and laugh while you're studying that you are telling them they should watch and subscribe and see for themselves...BAM!!!
You're welcome...glad to see you are still watching my videos! Please feel free to share my channel with your friends too:D
Thanks...WOW, what do I say to that?! 8th grade and learning college algebra...I wish you were in my class! Are you actually taking a class in school, on-line, or just because you want to learn? Whichever it is I hope you keep watching and learning as much as you can whether it's my channel or others! (I do hope it's mine:)
Knowledge is a powerful tool that you can never have too much of.
Thanks for that compliment and idea...I could make a whole new series of videos and call them that:)...but I'm sure there are copyright laws for that:(
Thanks for watching and liking my video and I hope I will be your go-to channel in the future:)
I love you Mr. Tarrou, you are an amazing math teacher for a person who is really bad in math. Thank you
Please feel free to share...I have alot of teachers that do actually share my channel with their students as additional reference material:)...And THANKS for supporting by subscribing!
I am watching you and I am from Iraq I am getting better with tow things the first one I am starting to understand English very good and getting really better with maths . so thank u and I hope u keep what u are doing
Great videos!! I'm going into 8th grade and learning college algebra and its really difficult your videos are a great help! Thank you so much!
I think that would be a GREAT idea!...and that might surprise more than just the teacher:) Thanks for supporting, liking and subscribing too! Please help my channel growth by sharing with others:D
Your the best just got a 97 on my latest test thanks to the help i received from your videos
THANK YOU SO MUCH!!! I am so happy I can help...and though I teach my actually classes like I do in my videos...it is nice to not have to worry about the bells ringing when I do a video. I hope I can continue to help you in your class and your grades go through the roof:D Please share my videos with your friends.
Yes...my 3 turned into a 5 magically! Thanks
Your welcome! Glad I could help:)
The base of the log is 5 and 5^3 equals 125.
you have taught me more than my calc teacher has.. bless you. (ps can I trade my teacher for you?)
That was Great Prof. Andrew, you surely saved my butt. Im in Calc now, and am a bit rusty on my college algebra after 4 years of having taken it. Now I feel I understand logarithms better than before. BANG!! lmao
Mr. Tarrou > Khan Academy....nuff said (y)
THANKS for such an outstanding math example Kulvir Singh ...BAM!!!
Its been 2 years since this comment and it STILL is completely true! Mr Tarrou your videos are of pure quality and have stood and will continue to set the standard for online math videos, i am very glad I found your channel!!
You are my savior haha, thank you so much for doing these videos! Oh and one more think, it broke my heart when you forgot to say "go do your homework!".... lol
You're welcome and THANK YOU for watching, learning and subbing Yaseen Moore !
This was one of my very early videos before I added all my silly little sayings and only had 15 minutes per video:)...But something tells me you did not need me to remind you:) Thanks fro being such a self-motivated student, we teachers appreciate that.
you make such great math videos! I am mexican and I was having trouble with all this but your explanation made it so much simpler!
Now with Closed Captions
Good eyes...but no, its a St Petersburg High Watch:)
+ProfRobBob St pete FL?
yes:)
Awesome ... I think imma start watching your vids before my teacher starts new sections so i could surprise hin with the right answers ... thanx nice videos btw
All of your videos have helped me a lot. Thank you.
You're welcome Chris Badger and thanks for helping me by liking and subbing too!

Thank you for appreciating my teaching style:)...and thank you for subscribing too. My channels growth is through the support of subscribers like you. Please share with your friends too...Thanks.
Yes..I mis-copied the -3. There is an annotation correction in the video, but annotations require Flash to be seen. Thank you for watching:)
I miscopied the number as I was writing the final answer. Sorry. There is an annotation correction, unfortunately you cannot see it without flash.
You teach 1,000 times better than my math teacher does.
Another wonderful video to supplement our learning. Thanks Mr. T and BAM! back at ya!
:)
THANK YOU! ...you can, 24/7, 435 videos to choose from...lol :)
I know it's not the same but I do appreciate the compliment Aaron!
Puts a smile on my face every time I watch, even when I'm in hair pulling work mode!
...and you will put a smile on my face if you take the time to like, SUBSCRIBE and share my channel with your friends, classmates and teachers...BAM!!!
Awsome! You narrowed it down, and that makes it all better for my understanding! Thanks!!
Looks like there is room for you to add BAM!!! to the back of your jersey:)
Thanks for watching!
Oh…yes of course. I miscopied the number. Thank you. There is an annotation correction, unfortunately you cannot see it without flash.
*mind blown* you're a genius I can't explain how much this helped since I have a test tomorrow and was a bit confused haha :P
Thanks for watching, liking, studying and subbing Dorian Brown and I hope you pass that test like BAM!!!
Yes...I see I can't copy numbers. I put in an annotation to correct that...Thank You!
As I do you for watching and subscribing!
Thank you, this helped me. You are my savior.
First time I heard that comparison!!
If I am at the correct moment in the video, because 5^3 is 125 so log(base 3)125 is 3
Your an amazing teacher, thank you so much for explaining the way you do.
Don't make me blush...
Thanks for subscribing and please share my channel with all your friends!
This video was very helpful. Thanks to you I'm getting an A in my College Algebra class. Thanks so much! #BAM!
That defiantly call for a BAM!!! 1vandela !
That's what I call teamwork...I supply the lessons and you do the studying and together that helps you make the grade:)
THANKS for choosing #ProfRobBob to learn from and subscribe to...please share my channel with your friends and classmates and tell them to like, subscribe and share too:D
@drummerbuddy15 You are very welcome...and thank you:) I hope you got that A+ you were expecting!!!!!
This was incredibly helpful, thanks for sharing! I was really struggling!
You're welcome...and thank you for studying and subbing and taking the time to thank the teacher...BAM!!!
Please share this free study resource with your teacher so the rest of the students know where to find this free after school help...BAM!!!
You are amazing and you are really helping me with my pre-calculus class.
THANK YOU Denyese for watching, liking and subbing!...and I hope you are sharing my channel with the rest of your class and friends too:D
I intend to clarity is important to me because many professors obviously know the math but cannot really teach it. I have singled you out because presently I am an undergraduate student pursuing a Teacher's Education degree with a concentration in mathematics. Professor I love your style and method of teaching. It does not get any clearer than this professor. (I will now be your student as well, for I have Calc 1 to 3 to complete in the near future, then comes linear algebra). THANK YOU, THANK YOU, THANK YOU.
Denyese Gonsalves You're welcome and if you continue to feel passionate about teaching it will never feel like a job to you:) I have been teaching for almost 19 years and I still love it...UA-cam has just taken that passion to a different level, making it possible for me to help students all over the world from the back room of my home...BAM!!! Thanks for being one of those students and I look forward to helping you thru Calc 1:)
Whoaa u got a lot of energy prof.
Keep up the good work sir...👍
Where's the video of conversion of natural logarithms to common logarithms?
You explained it so well. Thank you so much!!
+Matthew Troutman you are so welcome!
Thanks for learning and subbing...please keep spreading the word:D
That bam at the end made me smile.
Keep watching...there's plenty more where that came form...BAM!!!
Professor RobBob, thank you for another great video/lecture on Using Properties of Logarithms, however the equal signs are missing in all five examples. There is an error in example four where you have a minus 5 instead of minus 3. In the Properties section, M and N are supposed to be greater than zero. This must be stated after the Properties.
OMG! you are a such a great teacher.
THANKS Amina!
