Three young ones: 7, 8 and 12 year olds are enjoying and participating. Great job during the lockdown

[@cdmanor777]

OMG! I am 51 years young and still struggle with counting numbers quickly. Why weren't we taught this in school? I feel like a pro now. Can't wait to learn the multiplications faster now. Thank you for sharing this in layman's terms also I really appreciate it.

[@bunnyman6321]

How you making out in math now?

[@armorvestrus4119]

It worked the seem for me when adding large numbers. I hardly ever make a blunder now just because of those wonderful ( 0 ) place holders. And I am older then you. I always messed up trying to carry over the ones, but now no problems. I always add from left to right now. My teacher wouldn't let me do it that way in school I know now that my grades would have been much better.

[@MathAndScience]

You are so very welcome!

[@bluesteel1]

You're a great example of how math should be taught in schools .... unfortunately most teachers just vomit the text book

[@GloryGrullon]

I don't remember ever being taught looking for the compliments. I wish I could've found these videos a long time ago. How simple.

[@8151309522]

Glory khk

[@frankrod5150]

No wonder math was my favorite subject in school. I was really good at it. I have watched 2 of your videos and noticed that I taught myself how to count this way. I thought everybody did it this way. I feel so proud. Well anyways, I am homeschooling my kids. At this moment they are learning their addition facts. I was looking for something that will make it easier for them. I'm happy I found your channel. Thank you.

[@Xynful]

Same, I thought other people added this way already haha

[@Jissamar]

I'm a gradma on chemo and can learn Thank you very much

[@rosalindarcher6060]

I find it so fascinating. To one group of people (myself included) this is a revelation and truly transformative. To another, it comes completely naturally without being taught or pointed out at all. It’s all to do with how our individual brains process information. Despite being ‘naturally’ bright with excellent exam technique and strategy (not taught), I always struggled with maths and particularly mental maths. It’s easy to feel superior or ‘clever’ when things come naturally to you but I love it when people teach others strategies to help them. It’s one of the hardest things I think to disseminate and break down exactly what’s involved in what comes naturally to others. So I THANK you!

[@MathAndScience]

So happy you liked it! Jason, MathAndScience.com

[@jacobesther3349]

I have always stayed away from maths because it's kinda stressful and I couldn't cope with it that much so I abandoned it but it's like am playing a game learning compliments. It's awesome.

[@amariestrine1171]

your the wolds best math teacher!

[@cm8291]

I like how cute this comment is. Probably loves math now but lagging a bit in other areas :D

[@TheManicDishwasher]

I don't feel so stupid anymore. Thanks!

[@chancethesaver1354]

You are smart👍🏻

[@anasser]

I have been always afraid of math since I was in mid-school until I watched your videos and all it changed my mind about math. Thank you really.

[@bluesteel1]

Who else is watching this during lockdown

[@rajgopal5602]

Me me me

[@jacobesther3349]

I guess I am watching at home too.

[@anasser]

[@armorvestrus4119]

This is so great and easy. This method should be the first thing taught to children in school.

[@jimmojee]

This is amazing. I was familiar with compliments while learning the use of abacus. I had no idea of all these benefits . Thank you very much.

[@WittyKittyRitzy]

yay! im learning math all over again and feel smart! hah im 28

[@MM-lr5hv]

AwiZ that’s okay . I m 45 .I am learning again to teach my children. I am from Bangladesh and two years ago I have passed functional math . I don’t know when it will stop for me 🙄😁

[@Theegoaat]

Same here I have a new job and need to use basic math daily. Boy was I surprised how much I had forgotten.

Simplicity in numbers is beauty!

[@adriudrik]

Simply awesome. What a lesson! I've just seen the previous video and this one and I calculate 10x faster than before WOW

[@princesscharlen8389]

If this was how math was being thought I would have been a genius by now. Excellent way of teaching sir

[@kirunasaireru9106]

Great! I've only found out about this before entering high school.🙂

[@Sarah-l7f6o]

seriously, only some people (tutors/teachers) are gifted with such talent! I wish I had this kinda tutor at school! Life woud've been a breeze! Lol. Thx for all the lovely tips&tricks!

[@MM-lr5hv]

Math is a game or interesting puzzle so who feels playing math game , finds it interesting they actually find this kinds of tricks by themselves and more they practice it becomes more easy to count.

[@d3vinity]

Bless this free knowledge I appreciate ur work so much I never learned compliments and to add on my fingers until I grew up to use a calculator! Thx for making my life easier

[@naturallyvall]

Thank you Jason, I appreciate it! I appreciate you ! Love 💟

You Are The Best Math Teacher!!!!

[@avegaile8973]

it really helps me a lot! I subscribed🙂

[@SolemnGirl8]

i always did addition like this by adding compliments (plus i never knew they were called compliments until the last episode) and i was never taught by a teacher or anyone else by adding numbers in a column to 10. i just thought it was more logical to add numbers this way haha

[@thatonefrankie]

Thanks for the help Jason!

[@prixman300]

Cool. I've used this technique to add up my golf scorecard for many years.

[@oorterentity8095]

This is awesome. Thanks

[@midliss259]

So great mehn!!!

[@absurdism-yw]

the part about how to do it in your head faster .7:30 if you just visualize it and see the numbers and not waste time using words to explain stuff then you can do it much faster words are just meaningless symbols or sounds we made up to communicate to each other , but when communicating with yourself their unnecessary because of how long they take to say ,even though the idea could be represented instantly. that's also the reason abbreviations exist because saying 'LAUGH OUT LOUD' takes too long while 'LOL 'can be instant but a picture that means lol (like emoji's) is even faster. (i did not focus on grammar in this comment)

[@nimcomohamed1503]

I love it I will repeat Becoming I perfect .

[@ojoozerubabelogom8498]

Good teaching for young ones

[@gabrielbiniam7900]

Very useful thanks.

[@TanyaStar-no6fb]

Hi, I was just wondering if you have similar videos for subtraction? If no, any chances you can create one, my kids really like your videos.

[@abdu4066]

Thank you!!

[@opespeciais660]

Amazing thank you

[@WmLatin]

Compliments and grouping in addition- don't know what grade level this is but useful for anyone if they haven't been taught this 'tip'... or maybe mathophobic?

[@olaseindeloveth2394]

Thank you!

[@ausomeaspie]

This is sooooo helpful! Thank you so much!

Welcome!

[@georgendjadinganda3265]

Thank you very much in it help me and my sister🤩🥇📖🙏

[@freedomaugustus1555]

U really rock !!💖💖💖💖

[@migos00]

in the question 9+2+3+5+1 you can add 2+3 which gives you 5 so 5+5 is a complement then 9+1 which gives you 20

[@strickencreed5791]

U right

[@reedlee6830]

wow this made math easy for me

[@TheSep1599]

Do you know how to do stem and leaf and box whisker plots?

im 15 right now, and i've been doing that whole compliment thing for a couple of years ...

[@movies-sy3sy]

YOU ARE A GENIUS!!!!!!!!!!!

[@Twinkle6806]

Thank you for your uploaded video..to this I would like to add some thing...if u r adding a number to 9 or 8 or 7 or 6. what will u do?....you know 9=10-1 right,then if u add a number to 9(single digit) just minus 1 from the number and put 1 in front of it(no: obtained after deducting 1 from number .Hence answer will be 9+7=16(7-1 and put 1 in front of the number)then 8,8=10-2.Hence if u add a number ,for example 6,just minus 2 from 6 and put 1 in front of the answer.7=10-3, numbr-3,put 1infrnt

[@ankitasharma9036]

Deepa. C.G this is really great tip

[@mrgamerlion9591]

Thank you, mate

[@twistedhalo539]

Question: on the math problem 7, 1, 4 , 5, 3, 7, 9 @ time 9:38 ... wouldn't it be faster to do 7, 3, then 1, 4, 5, then 7,9....10/20/36, can visualize through the whole math problem instead of adding +4, +5, +7, you can visually see the whole problem better if you can combine the lesser numbers to 10 first or second. of course depending on the length of the math problem.

[@katek57]

Fantastic!

This is easy when I can see the numbers written but when I can’t see the numbers someone tells the numbers one after another and I have to add them , then ? All I can do is count on my fingers . Is there any other easy way ?

[@lokiuk]

of course I've learn something thank you

[@InterestingProblems]

I did the 6+2+2+5+9 differently, and I feel like it better demonstrates what this video is about, I know that 6 is one away from 5. 5+5=10 and 9+1=10 and 2+2=4 so 10+10+4=24 Essentially 6+2+2+5+9 = 1+5+2+2+5+9

[@fiyinjayabigeal9923]

thanks a lot

[@TraderKing83]

are you from the Pennsylvania?

[@marktizon1951]

wow very useful thnx jason=)

[@sirjsj13]

yeah it's a better way when the numbers are written on paper but when it is dictated.....i think it would be alittle bit harder... plsss do tutorials on that....

[@mainlyfwit2115]

I been doing the same since i was a kid but didn't quite know the fancy name. 👍🏻

[@sunnyle541]

thanks teacher,im waiting new video

[@jajafrancisco]

Thanks you are a super genius thank you

[@yawowusu-gyan2076]

but what if the numbers you have do not compliment each other , what skill or trick should one use.

[@fazeelalaher6250]

Thank you Awesome
