Thank you for always helping me seem brilliant in front of my teenager!

[@noahfarrell7082]

Hahahaha 😂😂

[@dcornerofficial2411]

Bro

[@tecmath]

You are. And thank you.

[@Sku11zDude]

Haha it's wholesome imagining that

[@ThePurplesquish]

I'm 55 years old, and somehow I managed to scrape through without ever knowing how to work out percentages. My eldest asked me to help her with percentages and I found this video. I can't believe it's so simple! Thank you!

[@user-rz8ld7iq8h]

Don't feel bad. I'm in my 50's too and I have forgotten a lot of the math that I learned because I don't use it on a regular basis as an adult. Keep practicing. You'll get better. Best wishes to you.

[@gtgb5680]

Ironically, I'm having a test tomorrow and one of the topics is percentages. Quite a coincidence that this was uploaded today. Thank you!

[@tecmath]

Good luck!

[@TheBaconStrip]

Thank you for this lesson. As always you make math seem quite simple. I was once so intimidated by math, but you're helping me take my confidence back.

[@beach-butterfly]

Thank you so much for this, my teenager is trying to learn Nat4 Maths and this made sense of the problems he had to do without a calculator in a way the course books couldn't!

[@LastRon1n]

I’m stupid when it come to percentages so I really do thank you for this video it helps so much

[@forestknowledge]

I needed this! Amazing refresher for quick mental math! Thank you!

[@Mukie20002]

Thanks a lot I was struggling a lot you deserve more than you are getting 😭😎

[@JogiGee17]

Thank you. This was way easier than what I was taught years ago.

[@zxuiji]

What were you taught? I don't even remember what I was taught, just did this method automatically (albeit slowly 'cus I forgot my times table XD)

[@tecmath]

Glad you liked it.

[@1myfriendjohn]

I always struggled with the divide by 100 method, but the 10 & 10 method is so much better for me. Thank you dude.

[@tecmath]

Thanks

[@S.Waters.]

This is brilliant! Thank you!

[@thedudeabides3138]

Sending you a virtual hug, thanks for this!

[@thelionbeast252]

Why were we never taught this in school? This method is 1000 times easier to follow. Keep up the good work tecmath.👍

[@sobster123]

Love it ❤❤❤

[@julianmcc9436]

Thank you so so much man! im 18, Im in high school but I dont do maths, only financial maths and inflation calculations so I have forgotten all this basic knowledge and im relearning what I need to know, I apprecate this.

[@PatrickAtchison-xf2et]

Bro, this is amazing! Thank you so much!

[@freeman10000]

This is nuts easy! Bravo

[@paul9570]

I wish you were my math teacher at school, you explain things so well. I hated math because the teacher was so strict and shouted at you if you were wrong. Kids were scared to ask questions because he would get mad if you didn't know how to do things. This was in the 70s & 80s though

[@r0dney211]

Brilliant...thanks very much appreciated

[@Hello-bc1em]

wow, first time ever understanding percentages. Ive not been able to learn off my teachers and ive just learnt in 5 minutes!

[@sweet_amira]

soper semple tanks my fren😁

[@louiseoloughlin2489]

Brilliant! 🙂👍

[@Ur.MomfAg]

Awesome 💯

[@baughsp]

Thank you so much Josh. I am a 51 year old man who struggles with mathematics. You helped me learn percentages in such a quick time. I will follow all your videos from now on 😊

[@refreshisnothaha]

Loser

[@analuisahering2043]

Excellent trick !!! Thank you so much for sharing 👍🏻💥Can you please show examples where the second figure doesn't end with a zero ?

[@denisetebbs2742]

Now that's not quite so easy 🥴

[@tecmath]

It still works in a similar way but I quite often then use other methods....I'll make a video soon.

[@analuisahering2043]

@@tecmath thank you so much for replying !!!! 👍🏻❤️🙂 Looking forward to it !

[@SIMPLEisWIN]

The only problem i have with this is when you take for ex. 24% of 60 div by 10 = 2.4 x 6. The 2*6 is easy enough to calculate (12). But the 0.4*6 is also just 40% of 6. And i find it hard to do in my head... In that case i could just do the whole problem like this 24% of 60 as 0,24* 60... But yeah, everything ells makes alot of sense. Thanks :)

[@TheBerlyn186]

Hello hope all is well I first want to say thank you for your free online education and for putting out Great content and being a great explainer just one question on the last problem 13% of 1200 how come we didn’t move the decimal to the left once to make it 1.3?

[@ElvinItaly]

Wonderful Tysm

[@NfShf]

Very helpful tysm

[@Sawbones.]

Thank youuuu

[@nataliameyer4947]

Lovely and easy

[@Mummydadhaba322]

Why all sir are taking 0 like (100,60,70) 8 just want to take out 47 and 56 that all are taking 0 no. Only what is this problem

[@Anime_Art_kdrama]

Good to know when shopping sales

[@kimjackson6845]

So helpful

[@user-nu5ll9rl6i]

Thanks

[@dereckc]

Thank you for the great explanation! I have one question: Why in 3% of 400 and 13% of 1200 the division by 10 or 100 doesn’t affect the percentage itself? It makes sense seeing it but I’d like to know why.

[@metallsnubben]

If I understand your question correctly, think of it like you had "(3 x 400)/(10 x 10)" and "(13 x 1200)/(10 x 10)". You're essentially "simplifying the fraction" and you know you have to divide by 10 twice, but it doesn't matter where you do it, you can do "one of them divided by 100" or "10 each". Since % just means divided by 100, you can rewrite it as 3% x 400 = (3/100) x 400 = (3 x 400)/100 = 3 x (400/100) and so on, the important thing is just that _somewhere_ along the way you're dividing by 100, multiplying by 400 etc. but you can move stuff around. This goes for when you _only_ have multiplication and division, when you also have addition/subtraction in the mix you of course have to keep track of brackets and what goes with what. In the first example of "61% x 80" you could just as well have turned it into "0.61 x 80" or "61 x 0.8", but it's probably going to be easier to do "10 each" and get the "6.1 x 8" And you likewise, "13 x 12" _is_ the same thing as "1.3 x 120", it's just a question of what you think is most convenient.

[@dereckc]

That makes perfect sense now! Thank you!

[@tecmath]

Well said

[@DearHenryA]

Brilliant

[@OGTrueX]

Amazing

[@latoyagadison1470]

hi. can you please me with dosage and calculation math? I failed that class and have to rekae in june.

[@scottdickson7047]

lovely! ... leaving a lovely comment😊

[@devjyotidebbarma7387]

Have a good day

[@tecmath]

And you too!

[@NicoLi-wh4rn]

Ty

[@Champion-flix]

Worked

[@Plazma110]

walks into class does nothing goes home and watches videos on the topic aces the test

[@xamanaxx]

So for example if the question was “40% of £130” would you work it out the same or differently because of the Pound sign? Another question: How would you work out this for example the question was “30% of 356” would you divide 30 and the divide 10 by 356 which would be 35.6 and work it out the same?

[@user-wl9em3ze3b]

I think I'm ready for my exams

[@arfan1989]

Very effective

[@phillipebrall9930]

I think this is brilliant. I am 72. Should have learned this in primary school.

[@VinayakGupta08_]

what about the no's that does not consists of zero's?

[@deracersyt264]

This is so easy. Why were we never taught to do it like this

[@Jucy667]

What app do you use to draw?

[@ZerooooooooooooooooooooO]

Sir this does not work with number like ... 26% of 33... Please give a short trick or I'm dull in maths

[@Foxy_ladyYTSL]

brilliant! divide by 10 divide by 10 is so much easier. Why couldn't my maths teacher teach like this??

[@10AntsTapDancing]

My teachers in the 50's and 60's couldn't teach me math so I was deemed stupid and lazy. Fascinating that you can teach me this in 5.09 minutes, lol.

[@alanwilson4860]

Watching this at 45 going wish I'd had a teacher like that.

[@hafsab6512]

Thanks soon muxh

[@MHPloni-kl5ec]

Lovely

[@thesazide2817]

Sir do you have any book

[@denisefitzpatrick9872]

Question? Why not just cut to the chase and multiply 61 x 80 = 48 .8

[@Umski]

Thanks, handy tip, although your examples all had quite nice round values that when divided by 10 or 100 gave easy to work with integers - it would still work with different values but wouldn't be quite as quick... e.g. in the shops when something is say 5.99 and has 30% off

[@Lilione111]

$5.99 is pretty much $6. I’m sure you won’t worry too much about the 1 cent 😄 30% of 6. Much easier.

[@Umski]

@@Lilione111 it’s the staff that are usually the problem - the number of times I’ve stood there telling them the number and they need to pull out their phone to use a calculator 🤦‍♂️😂

[@julians9763]

Thank you for the video Josh, the hidden message I shall say is , no matter how old we are , the simpler the explanation the better, and we can prevent future innumeracy and dyscalculia.

[@tecmath]

Thanks. This method is awesomely simple.

[@orac229]

I have trouble with questions like what % is 130 of 200. I also had a very interesting issue at work with some chemical lab test results which involved a sample from our work measured against the Lab reference. So work sample was 1000 and lab reference was 900 (which never changes) The % difference they gave was (I think 0.9%) but on investigation I believed it was wrong because they used the 1000 as the reference meaning 900 is a "decrease" from the 1000 so % difference = 0.9% The correct way should always be made from the 900 reference so it should be 1000 is an "increase" from the lab reference of 900 which is 10.1% What do you think?

[@tecmath]

130 of 200 would be worked out 130 divided by 200 x 100 = 65%

[@Diana-en3mn]

Why did you divide 24 by 10 but you didn't divide 13 and judt write it?

[@saraventura1333]

Love the accent pal

[@Babicoste]

What Kinda Sorcery Is This! Thanks...

[@samaskew176]

Wizardry 😮

[@unionjack8463]

Percentages are always in use. You can amaze the cashier by giving them exact change when you have add on sales tax! Cashless society really reduces brain power.

[@izegaegbe]

Where on earth were you 35 years ago. Primary school would have been a breeze 😂

[@MohammedMir-fq7or]

Wow
