Order of Operations & PEMDAS Made Easy! - [8-3-1]

In this lesson, you will learn how to perform order of operations using PEMDAS in math. PEMDAS means parenthesis, exponents, multiplication, division, addition, and subtraction in math. This is the proper order to calculate mathematical operations - hence it is called the order of operations. The first step is to identify any parenthesis in the expression. If there are parenthesis or brackets, do what is inside of those first. Next, perform exponents. Addition and subtraction are performed on the same level left to right. Multiplication and division are performed left to right as they are also on the same level.

I'm 63 and you're still teaching me math and making it fun . Thank you !!!

I just realized why I was never successful in Algebra when I was young. Won't say how old I am but I learned PEMDAS as Please Excuse My Dear Aunt Sally. This whole time I thought the order was exactly that. Addition before subtraction and multiplication before division. Now I know why I struggled so much in Algebra. I wish we had internet, and you tube back when I was at school. I am here today learning to teach my middle school aged child.

I was taught BODMAS - Brackets Of Division Multiplication Addition Subtraction.
However the left/right priority was also taught

I wouldn't accept an expression with the ./. division sign, preferring the to show a division. As you show later at 14mins,

im in love with this mans teaching im getting ready to take my accuplacer for college and I mean he breaks everything down to understand

[mydoggylives]

PEMDAS can still be used, you just have to remember the rule of left to right when performing Multiplication / Division and Addition / Subtraction. If it's learned correctly, then it still works. P-E-MD-AS. I see WHY you're saying that you don't like it though. I see people using it wrong often because they never learned the rule (or, as you say, they forgot it). Good lesson! 👍

another amazing lesson sir so understandable gives me confidence to move forward

[nfinitedestiny]

Your ability to teach is absolutely amazing! Ty for sharing your skills!

[ms.munchieeats]

Thank you, this has helped me so much and it's easier than P.E.M.D.A.S. I'm getting prepared to take my hiset math exam

[niyonkuruidrissa]

Your ability to teach is beyond the scope 💕💕💕!

[jamesjones]

Thank you so much!! Math is really like learning a new language an your an excellent teacher, when it comes to bridging that gap! Thank you so much God bless you!!

[aykilliesheall]

You are a great teacher. I wish growning up you where there... The school teachers were rude and exploited that I was ignorant to the subject... My apologies Thanks for your help...

[danielteyehuago]

Wow! This is very informative, thanks for sharing it with us. It worth it and the best tutorial on the topic for me.

According to the rules taught in German schools: 6/2(1+2) = 1
parentheses, exponents, IMPLIED MULTIPLIKATION, multiplication, division, addition, subtraction
6/2(1+2)= 6/ 2(3) = 6/ 2*3 = 6 [fraction bar] 2*3 = 6/6 = 1

I calculated it with a calculator prescribed by the German school authorities.
TI calculators are banned in German schools because they calculate according to PEMDAS
CASIO pocket calculators, FX-82DE, are required in German schools because they calculate according to PEJMDAS

Yes, MDAS is still used up to the 4th grade, but when higher mathematics is taught, PEJMDAS is normal

Thank you so much I always thought PEMDAS was so difficult but I didn't know it was this simple again thank you I now feel like I can ace that PEMDAS test😌

[callme_hazell]

This helped a lot! I have my exams coming up and this really helped :>>
I’ll tell my score after I get my result :)

One question no one never answers is what is the practical application of Order of Operations.
Why does it matter, left-to-right. PEMDAS BODMAS.
I can see two solutions but what is the meaning or purpose.

My books from 1970s show a strict left to right. P then E then M then D then A then S.
I have test papers from that era that's how we were taught.
I understand people today using this in a calculator get diff answer than the old method but in 1973
none of were using calculators, my question remains why does it even matter?

love your videos, especially, the combination and permutations videos. I'll keep watching.

[Joe_Narbaiz]

It is interesting that you included an explicit multiplication sign in the expression 35-3(4^2-10).
Can you explain why?
Don't implied multiplication and expressed multiplication yield the same result?

[johng.]

the reason multiplication and division are at the same level is that division doesn't exist, division is a multiplication, 15/5 is really 15*1/5
for this example it would be 10*(1/5)*2 so you could do the (1/5)*2*10 if you wanted to or 2*10*(1/5)
the same is true with subtraction it doesn't really exist, it is an addition 4+6-9 is really 4+6+(-9)

Excellent 👌👌 lesson thank you very much dear teacher

[rangarajunanjundagowder]

Sir there are four types of parenthesis, while removing this order of removal should strictly followed
