Unpopular doubt but I'm unable to solve √80 using this trick.

my tution teacher talks at 2x the speed and expects me to understand without explaining why we do things we do. tysmmmmmm

Wow this is literally the easiest way to find the GCF or HCF. Thank you for sharing this! Huge help! 🤩

thabk you so much

To multiply 23*24 without this trick.Multiply 23*25=575 then minus 23=552..

I’m literally watching this the day before I have my maths mocks. I’m cooked

Love the 3=6/2 and someold... why not simplify. One i would also add is when we have lets say x/y = c/v if we need lets say x. We put together diagonally so xv = yc then ÷ w v so that we get x=yc/v.

God bless you, you saved me hours of work. I can't believe they somehow managed to make this more complicated.

Isn't 408 minus 24 = to 384? How did you get 380 I believe that last one is wrong. And 380 times 50 is 19,000 not 19,200. I'm confused. Did I miss something you did for those 2 steps??

thanks mate

W vid

Nice round figures, how do you work out 15.7% of 324 = ?????.....

B

amazing!

3:17 in france we just say "cah-soh-toa", which also sounds like "casse toi"(f*ck off/go away). So we have c=a/h, s=o/h, and t=o/a 😀

thank you so much omg.

Shame about the acronym

I wish I can find this channel before my would have been better

To multiply 41*49 multiply 41*50=2050 first then deduct 41.Answer is therefore 2009.Nearest 5 10 and 50

They are teching

thank u

Thanks for the tips and tricks! But, besides that, what should you do if the first number is a negative? Like for example, 10,000 4,375 What would you say to do for this? I don't mind if unanswered but I'd love for you to reply. Thanks!

He explained this better than my teacher could 😅

any indians who just have it easy cuz of oshachota?

6x^2 + 20x + 16 = 0

Who teaches their kids this shit! This is mental abuse

It doesn't work on √22

in 2020, the second 2 counts itself and the first 2, which in turn counts that there are 2 2s and 2 0s, the first 2 points to zeroes, which don’t point to any digits, and we definitely don’t have to worry about the zeroes themselves, but the second 2 double points to every digit in the number, which is why 2*0+0*1+2*2+0*3=0+0+4+0=4

you can work out from the 2 that there are 2 digits that are 1s, which in turn means that 2 digits appear once each

thanks

thanks gang

Learnt new. Thanks so much. Amazing voice.

This video is criminally under-viewed.

63*67=4221.Multiply 3*7=21 write down as last two digits then to the left multiply 6*6+6=42.Answer becomes 4221

Easier trick.45 * 45.5*5=25 then add 4*4+4=20.Answer is 2025

All mentally 64821÷38= *1705,815788....*

Not good

Incredible! thanks for sharing :)

Would 45% of 460= 2070

this channel should be called Magic Maths !!!😆 thank you for your help !
