- Imagine finding simple solutions to seemingly complicated math problems and enjoying it, too. Math educator and author Greg Tang offers three cues - visualization, reasoning and number sense - to break down equations and preconceived stressors in ways that will take away bad memories and provide new solutions and a chuckle or two along the way.
Greg Tang is a Math educator and author.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at ted.com/tedx

This man is phenomenal.
I will be teaching math this year for the first time in 10 years.... thank you for taking the fear out of it for me. I’ll keep getting better at it so my students love it this year.
So how did it go? Teaching is one of the best ways to learn/re-learn! Hope you had fun.
Thank you Greg. You described me from beginning to end and i'm going to be applying these tools you've shared.
Yay! Greg Tang's children's books are outstanding. I am so happy to be able to share his talk, as well. Thank you
So fascinating!
I'd never thought of Math like that.
Went straight into the ‘watch later’ file. This is for viewing more than once. Both educational and fun. A big thanks.
so good - thank you Greg Tang for your great work!!!!
this is what I needed in school! now I have to try MAKE SENSE of math while studying my teacher degree. this was an awesome TEDx Talk - THANK YOU
I love this guy, who cares about sound quality!! He is a rock star!!! I have paid hundreds of dollars to see this presentation in person. You are fortunate to find it on YT!
well, like many of not so wealthy people like me resort to RUclips and expect decent audio quality from such a useful video in such a good forum like tedx. BTW I was able to listen to this on my phone. I shared the link with my friends. They are unable to listen to this at all. Then I tested it on another phone. I then realized that this video doesn't have any intelligible audio on some phones. surprised ? me too. But, like very few people, nowadays, I took time to rethink before commenting on someone s issue.
Similar to me. I had tried to watch this video by using two my phones. I had found broken audio. I had assumed, the problem had not been on this video. Then I watched it on my laptop, it worked.
My ears care about the sound quality, I can barely make him out. Thanks for being a spineless sycophant though. I'm just wondering what colour your nose is now with all the brown nosing you do.
Yeah... But if you can't actually hear anything... That's pretty important.
Weird though. It worked just fine in my car, but my phone and other Bluetooth speaker just produce a garbled mess. Great content otherwise.
Brilliant, you give me new pespective of mathematics
excellent show, thanks :)
I already use some of those ideas. It would be interesting to see how he would approach harder problems like the equations and fraction problems that don't have nice whole number answers.
Thank you, I love that
Most Excellent!!!!!
Great talk 👍
Instead of breaking 790 into 700 and 90 (to divide by 2) and then juggling 350 and 45 in your head, which is way too many digits for my tiny skull, it goes much easier if you break 790 into 800 and minus 10: you get 400 and minus 5 which is 395.
I did it via 700 and 90 in my head when he showed it on the screen, then the smoother road occurred to me afterwards.
Use headset for better understanding
Whaaat iiis wroooong wiiiith the aaaaaudio?
Mr Tang is addressing people with a certain level in maths. A level much higher than mine.
As a parent this helps. Nothing more frustrating with my kids coming home and asking for help and being told by my kid that I'm not doing it the way the teacher wants it done.
Also.. on the subtraction, If they don't learn the traditional method of borrowing then doing math outside of base 10 would be harder to learn I imagine. Octal or Hex math for instance would not work this way.
Thank you sir so much, I have a weird sense of satisfaction.
I did exactly what you're explaining and I got in trouble for not showing my work
Great
Good math methods!
So all of the number sense videos show me things I already did in my head since forever, because it just makes sense, but as soon as I started uni math became my nightmare .. And when I ask my tutors how to make sense of everything they just tell me learn it by heart and keep doing it... are there number sense videos on "higher math"?
Audio seems to work now. its either due to viewing on my laptop or the audio has been fixed
I'm live with him right now and its hard when the teachers shares her screen cuz its echoing
Sound problem
What if we do it this way
30 is 3\6 of what number
We divide 30 with 3 which will give us 10 and then 10 multiply by 6 is 60
I mean what if we avoid x which is alphabetical representation of a number and just focus on the arithmetic operations which are far easier to comprehend and teach
The audio seems broken
Fear is out. Everything makes sense now.
How did I get from the attack on Titan opening to here?
This worked last year, why is it not working? What happened?
No do it for geometry pls
3:58 Another way is to imagine a cube, since 27 is a cube number.
@Dirk Knight Did you mean '125' by any chance?
I met him when I was like 7
This guy came to one of my friend's schools. Started calling people cleaners if they got problems wrong. He also called a guy with long hair a girl. He is now a legend at the school apparently. Lol
Super important to make sure I didn't know he was wearing a jacket from North Face and using a mac...
You are a Cuddly Math- Ted-dy Bear 🐻 Thanks 🙏 Sir
What a rockstar 😂
Audio is not working well.
Is this the matrix
First, I guess. But what is up with the sound? it sounds like he's talking through a tin can 100 years ago. Fix, please!
John Possum same to me .i just couldnt understand what he says.
Sadly can’t hear anything understandable. 😢
nothing much
I love when smart people start explaining something "basic like a 6th grade math problem" and then proceeds to treat the explanation as if it's something natural like breathing. Typical teacher, never listening.
Wow, i got that goosebumps🤯 how smart he is.. 🥲🙏🏻
