Master the Order of Operations (PEMDAS) in Math - [5-7-5]

In this lesson, we will learn about the order of operations in math. Order of operations, also known as PEMDAS, tells us the correct order to perform calculations in math. At the highest level, we must do what is in parenthesis first. After this, the next highest priority is to do exponents, followed by multiplication and division, then finally addition and subtraction. It is important to perform the multiplication and division from left to right. Similarly, we do the addition and subtraction from left to right. We will practice order of operations by solving many problems step by step. We use order of operations in algebra, trig, calculus, physics, and beyond.

Thanks Jason. I'm 71 now and finally get it. Just wish I had you for a teacher 55+ years ago. 5 algebra regents to finally pass with a 67. Just couldn’t understand foreign languages; algebra, French, music.

This isn’t actually 100% exhaustive. You first do implicit inside *and* unimplicit parenthesis outside the parenthesis.

For example 2/4(8) is not equivalent to 2 / 4 * 8, but to 2 / (4*8): since in this case 2/4(8) is actually 2/32 <-> 2/(4*8) or 2 / 4(8). You see this very commonly with cases like 2/ 4a where a in this case where a is 8

This is what causes so much confusion on these popular meme posts where people argue over endlessly without fully understanding the issue. It doesn’t change the order of operations at all, it is just a more natural way of markup that reduces implicitly declared properties which you do need to add for computers

Your channel is real school,
Your message is delivered worldly,
You are doing much better than many big educational institutions particularly in our third counties

Good afternoon Jason from Math and Science, I am not sure that you preferred to be called Jason or professor.

My name is Marcia Jacobs presently attended Queens Borough Community College fall semester of 2021, subject taken was math 119.
Prior to taking Math 119 Fall semester I reviewed basic math and pre algebra you really showed me that I missed the concept in high school and any student whom watched your instruction in basic math, pre algebra and college algebra will never failed math again. your instruction, illustration and information was enforced, points made was very strong after watching your videos on youtube I will meet my goal in math. After all pre algebra in High School seem like it came out of the twilight zone, my highest score in high school was 75, now I feel very confident of 100 which is my goal.

I would like to take the time to Thank You for sharing your resources on youtube which help a novice student while I took math and expecially during Math 119.

Hoping you and your family had a happy holiday and a happy new Year. Many blessing in future endeavour.

Thank You
Marcia Jacobs

really you're a good teacher and thank you God bless you

[LQVEGA]

really now clear for me the proper order of calculating numbers in different operations with parenthesis..

Thanks sir, for sharing the knowledge, appreciate it very much, can share it to everyone..

God bless.

Just watched your video with my son and right away we learned your strategy. I think it’s great how you teach and explain. Thank you 🙏🏼

[bryyhuh]

You are a really great teacher, I managed to pass my online math test all because of watching your videos of Math and Science! Thank you so much and god bless you!😁

[alexandria]

hey!! im a pretty young student and I’m still trying to learn a lot of stuff but I’m going to be using this video as a guide to help me and I kind of already understand orders of operations but my teacher makes it very.. very confusing..

we learned the method of "PEMDAS" and it really confused me because one of my biggest downfalls is asking waaayyy oo many questions in my head that confuses me, but anyway, out of 50 stars, im gonna say how much I understand orders of operation and hopefully one day it reaches 50

for now : ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️

when you realise the 7*3 is 7+7+7 you can start with addition and end with addition. the reason you don't add to a multiple is because the two terms are multiples, so in this instance 7*3 is either 3 lots of 7 or 7 lots of 3, if you added the 2 to the 3 you would be doing 5 lots of 7 / 7 lots of 5. so you would be adding 14 not 2. you can actually do the addition first as long as the addition is a multiple of one of the terms and you add it as a multiple, for instance 7*5+10 10 is 2 lots of 5 so you could add 2 to the 7 and you would then have 9 lots of 5.
when you understand what is actually happening and why you need to carry out the operations in a specific order, you no longer need to follow that order. you can do it in any order you like as it is all addition and you can do addition in any order you like.

I know everything about this but thank you 😊

I love watching your channel, I'm retired, but still good for the brain.

[donames]

Great video like always! In the future put the notes such as ( ), ×, ÷, +, - on every white board if practical. Thanks for your wonderful videos.

[debjanim]

Can you please write the fullform of P and E stand for? We learnt

[langchang]

Hey Jason,
Question does your Algebra 2 course include Advanced Algebra, algebra word problems and Matrix algebra like your algebra 2 tutor did?

If not what order should I follow it after completing algebra 2 course?

[kelliephillips]

I appreciate that you have neat handwriting.

[cathystillman]

Great job at explaining … going show my grandson

[taethegreat]

I am so thankfull i dont think i can find any teacher that good at explaining and teaching Thank you so much you helped me alot!

[agooddaytofight]

Hands down, one of the best teachers out there.
I have subscribed as a member, to view all the lessons on the website, and so far it is the best value I ever got from my education investments.
I mean - every lesson is top tier explanation.
Don`t get me wrong, but I am kind of glad that you left NASA to pursue educational projects :D
We can survive without a spacecraft or two, but we won`t survive without great tutors.

I wish your videos went in order for easy to follow procedures.
