Kartikeya SarinDay agobro if no one got it by now...this is using Vedic mathematics...

Jace Kelly4 days agoOkay TVclip I watched it geez

fun fus5 days ago1+-2+3×(4+65×7×8+9) = 10958

Phuoc Tran7 days agoCan u give me a copy of that?

Rolf Mohme8 days agoI confirm the result of the original author. I could not find a

"normal" solution even though I tried potentiating and

allowed complex intermediate results. The best approximation is:

1+(2-3^4^(5/6/7))^-8+9 = 10958.00205791. A formula that works but

does not conform to the rules is: 0.1*(-2+3+4+5^6)*7+8+9 = 10958.

fun fus5 days ago1+-2+3×(4+65×7×8+9)

What's on my mind9 days agoHumans are so predictable, that I also chose 2 as the 4th number.

Adil but with a B11 days agoevery number's chill until the 10.958 comes in.

Milla Saunders15 days ago^{+1}What a useless thing to memorize.

Earl LaVallee15 days ago^{+1}This seems to work for me: ((1+((23*34)*(((5-6)+7)+8)))+9)

Jonid Crushfire14 days agoClose, but you added an extra 3 in there

dabberdooder16 days ago10,958 is just the premium model

Alexei Alferov17 days ago(2^5*7^3-(9+8-1+6-4))

the TOMSTER18 days agonot that I'm not interested... but what comes out of this? this is play, right?! there is no prove, there is no higher field of Maths originating from this, its just fun and games... or am I missing something?

Jacob Woodson Music18 days agoOKAY I'M WATCHING IT TVclip! WILL YOU STOP RECOMMENDING THIS TO ME???

Robert Chupein18 days ago^{+2}(1234−5)×6+7×8^√9=10958.

Robert Chupein14 days ago+Jonid Crushfire if exponents are allowed so should roots.

Jonid Crushfire14 days ago^{+1}If the square root is allowed, this does work. I think it was the simple operators and exponents, but this does indeed work.

Runaway TV19 days agoWhy does this feel like a tai lopez add ?

DEVUNK8819 days agoI bet the numberphile would have 2.8million more subscribers if he didnt use permanent markers on brown paper......

Leo17920 days ago^{+3}2:00 "Oh, I've done 2 pluses there, that is a mega plus, oh my goodness, that's pretty plus"

Techoo Hut21 day ago^{+1}With square roots you can do this:

(1234−5)×6+7×8^√9=10958

Techoo Hut17 days agoBecause 7*(8)^√3 = 3584

If u still not get it, search for BODMAS rule

Techoo Hut17 days ago+Vilho 7374 + 7 * (8)^√9 = 7374 + 3584

Vilho17 days ago+Techoo Hut (1234-5)=1229

1229×6=7374

7374+7×8=7430

7430^√9(=3) = 410,172,407,000

Tell me what did I do wrong

Techoo Hut18 days agoI think you need some more work on your mathematics

Colonel Burton22 days agoAnd I thought I was a numberphile because I thought that it's pretty divine that 777 = 3x7x37

ProVampFire22 days agoYou need to get to the point a lot faster dude

Patrick McManus23 days agoWhat about the 52 in the single digits?

11S53 LIAW ZHONG-WEI24 days agoPoor Matt, goes to the beach to memorize pages of numbers.

11S53 LIAW ZHONG-WEI24 days agoA mega-plus, aka a Parker plus

Weeping Dalek25 days agoI'll ruin the 3 digit number trick by giving you 0

weejams25 days agoSounds like a bunch of Common Core BS to me. 4 = 2x8-12. The simple answer is 2x2 equals 4.

Maybe just maybe mathematics is not the key to the Universe with the exceptions of 1s an 0s in certain series of repetitiously?

Dylan LoMonth agolol I actually saw an ad that was asking you to get to 101 with 10, 10, and 10 before this.

ThreeBall WillyMonth agoI'm 2:35 into the video when I paused to state that little game you're playing is like the "game" cashiers "play" when handing back change; handing back remaining currency in as few denominations as possible.

John CoffeeMonth agoTotally pointless.

César RabbitMonth agoWatch the video.

Oliver HartmanMonth agowhy is he using x instead of * ???????? (something tells me he didn't enjoy algebra)

ezio auditore28 days ago+Oliver Hartman Yeah, that's... just not true at all.

Oliver HartmanMonth agox is not recommended, and can seriously ruin your process of solving any problem with a variable "x"

ezio auditoreMonth agoBecause X is also the symbol for multiplication...?

Simon opdebeeckMonth ago666=9(9*9-(9-sqrt(9)))

J CMonth agoMicolash? Is that you?

cryonide2008Month agoAll this craziness, but the guy doesn't offer his solution. Weak, worthless video. He should stick to knitting and keep his day job at McDonalds.

craig fergunsonMonth ago"Natural numbers from 0 to 11111 - except one: 10958 - are written in terms of 1 to 9 in two different ways. The first one in increasing order of 1 to 9, and the second one in decreasing order. This is done by using the operations of addition, subtraction, multiplication, division and potentiation.

Jenny SaundersMonth ago^{+1}[(8+5+2-4)*(9+1)^3]-(6*7)=10958

WrutschgeluckMonth agonot bad, now turn it in the right order... :-P

XedronMonth ago^{+2}DEAR TVclip I FINALLY WATCHED THIS VIDEO NOW PLEASE STOP RECOMMENDING IT TO ME

Karim BenzemaMonth agoEXACTLY !

Jenny SaundersMonth ago11*(11-1)^(1+1+1)-[((1+1+1+1)*11)-1-1]=10958, quite complicated and possibly too many steps to solving it, right.

bodysnatchers 4 everMonth agoim a dumbass idk why im even attempting to solve this but im gonna give it a go anyway wooo

3liMonth agowhat a waste of trees

betterertMonth ago^{+3}write out 814 using zeroes

haha bet u cant

Bruce ShankleMonth agoDoopliss Yeah that would totally work.

betterertMonth ago+Doopliss oh

DooplissMonth ago+betterert I don't know anything about that, all I know is it's generally accepted to be 1.

betterertMonth ago^{+1}+Doopliss what if 0^0 = 0??

numberphile made a video about it called "problems with zero"

DooplissMonth ago^{+1}(0^0)+(0^0)+(0^0)+(0^0)+(0^0)... 814 times.
