Why PEMDAS Is A Failure

Though mathematics prides itself on consistency and singular solutions, competing order of operation systems create ambiguity in interpreting identical problems. While acknowledging the historical importance of the conventional order dating back to the 16th century, in this video I discuss an approach for future generations. A healthy skepticism of any singular system encourages deeper understanding, and a broader perspective of mathematics beyond specific methods, highlighting its inherent creativity for diverse applications.

plz create a ethical hacking course also if you can plz teach c/c++ for making payloads

Is there a way to test 7:47 a consistent order of operations with code and geometry?

[jeronimopichardo]

OMG this is really nice, love you mate!

[lucijahorvatinovic]

Highly recommend this video and we will be back for sure.

[mariamary]

Thank you for finally saying what I feel

[LukeAvedon]

I saw you featured by the Primeagen. Your famous now dawg.

[Veesworldmedia]

Covert operations to fractional form and it makes more sense

[alliealma]

I didnt know BODMAS is the same as USA

[adaadah]

Very interesting to learn about this now

[avagrace]

I always thought pemdas as a bad system

[svrmohan]

Sorry, math is not broken. I did masters in mathematics without ever having to worry about this issue. The solution is simply represent the problems in a clear and non confusing manner. Even this expression or equation you have can easily represented in a way it’s clear with additional paranthesis.

Hi sir you are giving best videos and also good information. One day you will get millions of subscribers.

It's funny how passionate people get over this issue. I think they like complaining about it!

I"m not sure I agree with your idea to "teach the controversy." That might be interesting to already highly math-literate students, but I think it would just further confuse those who struggle with it. I'd need to do some further research about WHY this has been an issue, why people differ on their opinions of what the order of operations should be, etc. You allude to thiese differences but don't really spell them out, which is fine.

I interpret the expression as equalling 16 since, to me, 8 / 2 (4) = 8 / 2 * 4, and division and multiplication have the same priority, so we go left to right. So, obviously, this is the way I would prefer things to be taught, though I'm open to other ideas since I don't have much reason to think this is the BEST way.

And what would the BEST way look like? How would we know it's the best? Probably through some controlled experiment, but I doubt this has been or ever will be done. Oh well.

Now, if I really wanted to be controversial, I would say, honestly, the kids are right. They will never use math beyond basic arithmatic, and so they don't need to learn it. I know! I think, instead of wasting time trying to guide every student up the mountain to calculus, we should stop just before algebra, and we should emphasize mental calculation. Maybe throw in a bit of geometry for good measure. That would about cover your real-world need for math in my estimation.

For those kids who really like math, more advanced classes should be offered.

Great video! I'm enjoying your channel a lot.

Wow. I actually don't remember getting taught anything like pemdas at school. They just did so many problems that you kinda got it like a language.

[alexneudatchin]

fun thing is if you try -8 in power of -3 it will work on ti calc but will not on hp. Really it must not work

[laser]

I put one of the examples from social media into 5 different publicly available AIs and got 2 different answers as well. They can not agree on these either.

[AhmadKouta]

LOL, this left me considering a new tech talk together :) Great job Josh!

This video raises a fascinating point about the tension between consistency and innovation in mathematics. So yes, an excellent on point presentation! Your exploration of alternative order of operations systems was thought-provoking. While the conventional approach has served us well for centuries, I appreciate your call for a broader perspective that fosters deeper understanding and creativity in future generations. Mathematics thrives on exploration and diverse applications, and encouraging healthy skepticism of singular systems can be instrumental in achieving this.

i never was taught any of this in school

[Abcefg]

true mathematician would use the problem as a counterexample to prove that PEMDAS is inconsistent

is there a point to illogical math? 🤦‍♂
