I clicked on this by accident, and now I'm a human calculator. Thank you!
I was just mindlessly letting my brainrot and then due to my attention span I accidentally clicked on this too, now I have several phds and everybody is after my head after I proved god isn't real using math, Mondays amirite

another funny trick is - every 2 digit number times 101 gives this 2digit twice: 45 x 101 = 4545, 92 x 101 = 9292, 21 x 101 = 2121
Awesome. Thanks. Jesus loves you by the way
Any 2 digit x 100 will just add two zeros, so when you multiply it by on more you add that 2 digit one more time to make that.
@@manzisb unnecessary
@@ExzaktVidThis also applies to any digits as long as they multiplied by 10,100,1000,10000,etc!
@@ingcrafter Why does it bother you so much you have to comment about it? It's a beautiful message, it's true and it doesn't do any harm. He loves you too, even if you don't believe it
This is actually really cool! Usually these things on yt shorts are fake and don't work, but this is actually true. Keep up the good work!
Glad you liked it!
@@learn.with.mahbubnow I can show off to my friends
STRAIGHT TO THE POINT!!! I was shocked but thank you so much!!
This is what should be taught in schools. Like this actually makes sense
Man if you keep doing these vids i just might die out of happiness😅
So useful thanks for sharing great information 👍
finally the one math teacher that teached properly
Taught* sorry lol
@@livy4954 it can either be teached or taught, i perfer teached since its much more easier to spell, thanks for the correction though
@@Ehanray what, I'm pretty sure theres no word called teached in English, and no problem it wasnt necessary to correct you lol
Yeah teached isn't a word the word is taught not teached
@@EhanrayOtha reached nu onnume illa
So mind blowing video!!🤯
Thanks a lot.
97x94=(97x95)-97=(96^2-1^2)-97=9216-1-97=9118. Also, Trick 3 intrigued me, so I extended it! Its general form is definitely harder, but I think it's pretty cool, and especially useful for multiplying two *3*-digit numbers ending in 5. 45x125=? Start with 2x4x12+4+12=96+16=112. Since the result is even, divide by 2 (56), and add a 25 onto the end. 45x125=5625. 95x145=? Start with 2x9x14+9+14=252+23=275. Since the result is odd, subtract 1 (274), divide by 2 (137), and add a 75 onto the end. 95x145=13775. 345x615=? 2x34x61+34+61=4148+95=4243=odd, 4243-1=4242, 4242/2=2121, 345x615=212175.
it's so amazing!
Loved it Mahbub !! Thanks
Good work , keep it up !

WOw thank you very much for the trick this is actually really helpful and awesome!! u just earned a loyal subscriber!
Great job, thanks
Super class sir thankyou 🙏🙏🙏
Thank you so much for sharing this sir
Thank you so much for the content.
thanks for sharing ❤❤❤❤❤
Thanks for showing this technique.
God bless you Mahbub 🙏🏻
Amazing ! Thanks so much
I had found out about the first trick 11 while i was memorising the multiplication. Keep the journey, your video is so impressing.
Thanks for, math hero work, better world
This is so cool! Thank you!
94 is 6 shy of 100....100x 97 is 9700, that is 6 97s too many. 9700 - 600 (97 is 3 shy of 100) is 9100. 100 is 3 moree than 97, so we subtracted 3 too many, 6 times., so 6x 3 is 18...9100+18 is 9118
11 is a bad example bc you could just add a zero and plus the number...
197x11. 1970 + 197
@@stephenremo9200 neither a bad, nor good example. Just ANOTHER ex of ewhat said above. Realize 11 is just 10+1. So 11*X = 10X + X. Always true.
What do u mean shy
@@aungphyo3032
In this case it means short
@@stephenremo9200 thanks
Thanks.
Thank you.
Thanks, I appreciate it.
The best math teacher in my life!

I am so lucky to find this video
Thank you very much for your effort
Thanks sir❤
Thanks
That’s actually really cool
Thanks U soo much for Ur efforts 😌😌🐱🐱
First one I found that isn’t made up! Great job!
wow, impressive
Pedantic point (I can't help it): "lightening" means making something lighter. The word you want is "lightning" which refers to an electric bolt from the clouds during a thunderstorm.
I don't mean to take anything away from the point of the video, which is great content.
Oh god! I didn't notice it. 🫣 Take love dear! ❤️
Very cool! ^_^
These cases are really specific
This was really helpful, thank you!
bro then what about 29 multiply by 12?
this is super beautifull
this is a great video, liked and subbed, I want MORE!
Will make more videos every month hopefully. please watch other videos as well. Thanks for your words.
Thank you sir 😇💪🧠
❤️❤️
Mahbub come to save the day again.
This is so cool! Thanks for sharing!
I did not get the shortcut for the last part...6:39. Can you explain one more time?

@@learn.with.mahbub Ok, I got it! You are amazing!
❤️
this is actually crazy 🤠
Cool
You take the multiple of 10s nearest to any of the multiplier like in this 97*93=97*90 +97*3 in this case you already know there is a last zero in the right hand first side so the next multiplication is easier
Terima kasih penjelasannya
Terima kasih kembali
I’m ready for my test
mr mahbub please switch with my math teacher 😭
Actually
Wow
Nice video. Pleased to see this from someone in bd❤
wawawawa
Lightning!

More pls
This is pretty crazy you got a sub lol
❤
Woow,didn't know this
Love it! Thank you very much
❤️❤️❤️
my exam istomorrow and this help
97*93= (100-3)*(100-7)= 10000-100*(3+7)+21=10000-1000+21=9021+21=9021, or
97*96= (100-3)*(100-4)= 10000-100*(3+4)+18=10000-700+12=9300+12=9312
your name is such a beautiful name
mahbub means a lovely person
Who else stop after he started multiplying higher than 11 ? 😂

YOU JUST SAVED MY ASS i have a maths exam in a week and i waste so much time typing everything in a calculator and as someone with special needs, i really need my time.
All the best for your exam! ❤️
@@learn.with.mahbub Thank you so much❤
Do you know? I'm almost sixty, and YOU are making me become a Walking
Calculator overnight. But it's morning here. lol I'm indeed very intrigued by this
WOW! You don't know how many Math Geniuses you are creating do you?
I didn't think so. You are probably changing lives at the drop of a hat and not
even knowing you are doing such. Do you understand that? WOW!!!
Ponder into Wonder. I am!!!
Awesome. Thanks. Jesus loves you by the way
Your tricks are so helpful. Now I can throw out my calculator.
Can you please teach me how to count 16×27 = 432? I found that 6×7 = 42 and 1+2= 3. Are there any skill included?
Damn!
