How do contend with the argument that older generations (before the internet) were taught PEMDAS and can get the answers correct? Now all of sudden PEMDAS (Mnemonic-Memory Aid) for the Order of Operations is incorrect? I dont buy it. The Ambiguity comes in because 1 of 2 things 1. Teacher's are not explaining Mnemonics correctly (I don't believe this). If that were the case, that would mean every teacher who taught PEMDAS would be wrong for teaching it. 2. Students aren't paying attention in math class when these types of problems are being presented. Students then want to blame the education system for not showing them (I believe this).

Hey man, really appreciate this video. We've been reviewing direct, inverse, and joint variation, but for joint variation especially, this was very helpful. Keep up the great work, and I wish you good luck on 100K so more people can see this!

@24:29 there is another method that cuts down 4 digits number faster than doubling the ones.

Excellent job! Will be sharing this with my students.

I can't believe you guys don't have more attention. Great intro, great explanation on everything Thankyou for posting this

i've been studying word problems for a year now and still don't get how people know how to arrange the numbers into an equation.

Great Video! Thanks for the shortcuts. 👍

Nice one lods from ph

Mmm-humm !!!! 😍

I have not done any math in over 30 years and did not remember anything about Algebra. MR WHITT, you are my hero and made it very easy to understand. I am having a really hard time following my professor. Thank you for making it look so easy

x=0 y=cos(5x) [0,5 0 0] 0 = y , x = 0 ax y-x g = 0. This is correct 👌 Sir 😊, I have imposter syndrome and am like Uncle Birdie

x=0 y=cos(5x) [0,5 0 0] 0 = y , x = 0 ax y-x g = 0.

x=0 y=cos(5x) [0,5 0 0] 0 = y , x = 0 ax y-x g = 0.

Just bummed 😞 over money for weed and boarding. Mail late🎉it story time ⏲️ 5th 😅

In(x^3 - x^n-/+1 = gx^0 = x^2 +/- 1x = y x^3 lna x.

[e^x] +/- e = a 1 y = e^x -/+ e^x a 1 = 0 - 1 ax = g.

p ax g= f^0x [e5-1] abc y = write replies to comment to: 80^0 a,0 a+/- 1 = 1 : 🔐 up Math, Calculus AP Stare 😀 at Hw 101 😅

p ax g= f^0x [e5-1] abc y = write replies to comment to: 80^0 a,0 a+/- 1 = 1

WTF????!!!!.....

Brilliant explanation! Thank You❤

bam!

love it!

this is precious stuff yo !!! Reeally dig your style and effective claritications, teach. Mounts of thanks for your work. =)

Just viewing this! Thank You for the clarification ❤

Thank you so much, Mr. Whitt!! Perfectly explained and demonstrated as always. I love your teaching style and the red boxes, and the intros and outros are a hoot! All of your videos are extremely helpful and very much appreciated!

This was fun.

My scientific calculator when I put in 6/2(2+1) gives me 1 as the result not 9. So obviously BIDMAS does not apply in this case (and, I suppose, in plenty other cases). While I do understand how the result of 1 was reached, I don't understand why BIDMAS fails in this case, and what other rule, that 'overrules' BIDMAS, applies instead (and, please, those of you with degrees in maths, engineering, physics, and whatnot, or adolescents with good maths, don't bother to show off here, unless you can clearly communicate -which requires special skills and experience- what you already know to those who don't, thank you).

Where have you been?

At 14:50 what exactly distinguishes the 2 as being negative? And not a minus symbol? Can anyone help me understand?

A ordem das operações é a verdadeira análise de uma expressão, já o PEMDAS é apenas um gancho mnemônico. Recitar e seguir o PEMDAS sem saber os detalhes da ordem das operações não adianta nada. Se você aprende a ordem das operações sem PEMDAS tudo bem e se você aprende o PEMDAS como gatilho mental para lembrar a ordem das operações tudo bem também. Só não pode fazer uma coisa em detrimento da outra como se só uma fosse a única forma de aprender. 😊 Ps. Muitíssimo obrigado pelo seus ótimos vídeos🙏🏼🫂

This is why YOUR video, is completely wrong usining a simple fact that you probably didn't know, the division symbol (÷) and the fraction symbol (/) are not the same thing, when you have let's say a/bc, it's not the same as a÷bc, The Division Sign (÷) represents the operation of division in a single symbol. For example, a ÷ b directly indicates that a is being divided by b, Generally, it does not show the result as a part of a whole, It simply indicates an operation. as opposed to The Fraction Notation (/) that represents division as a ratio or fraction. For instance, a/b​ also indicates that a is divided by b, but it can also imply a relationship between a and b as parts of a whole, it provides a visual representation of division as a part-to-whole relationship, making it clearer when working with composite fractions or more complex mathematical expressions. For example, 3/4 clearly indicates three parts of a whole that is divided into four. Or if we bring another constant (C), Then in this instance the Division Sign (÷) Which Represents the operation of division using a single symbol, with an example of : A÷B÷C: This indicates A divided by B, and then the result divided by C. as opposed to the Fraction Notation (/) Will Represent a division in a more structured format. For instance: A/(B×C)​: This indicates A is divided by the product of B and C. In contrast, (A/B)/C shows that A is first divided by B, and the result is then divided by C. So again, PEMDAS is not wrong, and the equation does really equal to 9. Just simplify the equation when defining 6 as X and treating the answer as 9, divide both sides by (2+1), we'll get x/2=9/(2+1), now solve for X to get X=6, which is what we defined X as. Now do the exact same thing but treat the equation as equal to 1, we again divide both sides by (2+1) to get x/2=1/(2+1), solve for X, x/2=1/3, x=2/3 which is NOT what we defined X to be. Now really we got real answers without the Division Sign in them, by simplifying the equation we get the exact same thing but in a different way. In conclusion, yes the answer is 6, and yes both the Division Operator and the Fraction Notation do represent the operation of "Division" but simply in different ways.

First rule should be: Put first, [everything you WANT to devide], in brackets.

Well presented; thank you for sharing.

I have seen some problems on Facebook, using the factorial symbol which falls under the exponent.

5:09 is my all time favorite! Get them arrows POPPIN' lol. I stumbled onto your videos and will be purposely watching moving forward! Your explanations are clear and concise, being a lefty is a plus too : )😍 10.6.2024 15:40 (3:40pm cst)

Thank very much Mr....very clear example

what app are u using sir?

PEMDAS is not a rule decided by math authorities, nor is it correct. The rule of "Left to right" is not always correct. Please see the proof at kzbin.info/www/bejne/aqmQc5aPeM5-ec0

Your video was extremely helpful, thank you so much

This is a big help. Thank you!

That was awesome. Going to use the tip about circling the negative number as a reminder and I will always think of arrows POPPIN'! Thank you so much

Oswald Trafficway

with finding the derivative of sin, cos, tan, etc. Should be reference the trigonometric identities? tan = sec^2 had me lost

Great examples. Great explanation. FBT greatest KZbin tutorial. Thank you Mr. Whitt

I really enjoy how these problems were broke down to help you understand, being that math is not my best subject. But this process the order of operatiion really made it easier for me to understand, Thank you.

W...O..W..THANKS!

OMG! This is the second time I am taking algebra 151 and for the first time I actually understand it and I like this subject. Thank you so much for making this an easy tutorial with some laughter. With this upcoming course, I hope my anxieties subsides...I just have to hear your voice in my head as I am taking my tests.

very clear thanks ...

Given that division is neither associative nor commutative, what probability is the proven answer derived from utilizing distribution of a rate reducing function[expression] through grouping symbols when compared to utilizing PEMDAS which order does not matter as long as it is calculated from left to right...
