Question

PEMDAS LESSONS: HERE TO PROVE HOW PEMDAS IS WRONG. If anyone needs help I am here and just ask your PEMDAS QUESTION AND I CAN EXPLAIN IT. sorry for caps

Answer 1

PEMDAS is really PEMoDAoS.

Answer 2

The o stands for or.

Answer 3

I have tons of people who I know that get this incorrect. I have also made the same mistakes as some people have and will always make mistakes since that is what makes us human. So I am just here to say that this can be easy if you believe you can do it and try your best and learn from your mistakes.

Answer 4

Parentheses Exponents Multiplication Or Division Adding and Subtraction

Answer 5

The or is for just clarifying you do which ever comes first meaning if you have 17 * 3 + 6/2 in this order. You would go for multiplication since it comes before division

Answer 6

The teachers should tell their students that.

Answer 7

yeah ikr

Answer 8

I learned it and sucked at it.

Answer 9

Then I met a math guy who told me it is different and it is PEMoDAoS

Answer 10

which really helped me

Answer 11

also the same goes for division meaning if it is 16/2 + 17 * 4 you would go for division

Answer 12

and vice versa

Answer 13

In all reality, there is no such thing as subtraction or division, so it's just PEMA

Answer 14

I usually like to write it like this:
P
E
MD
AS

It's like levels.
The P takes highest priority, and we can see that M and D are on the same level.

Answer 15

true that is another way to put it

Answer 16

brb

Answer 17

hehe ya i like that :)
when you finally realize that subtraction is just a myth XD

Answer 18

could also argue there's no such thing as multiplication or exponents since they stem from addition, but I like them for simplicity's sake

PEMoDos or PEMoDaS?

Answer 20

The thing they teach with PEMDAS is:

Multiplication and division, whichever comes first when you go left to right.
Addition and subtraction, whichever comes first when you go left to right.

Answer 21

true

Answer 22

Awesome! Keep up the good work!

@Liam2004

Answer 23

for some teachers and then they say use PEMDAS which confuses kids

Answer 24

Thx @AihberKhan

Answer 25

What I hate about 4th and 5th grade teachers they keep on saying use PEMDAS not use PEMoDAoS

Answer 26

so the kids get confused and are failing tests.

Answer 27

and don't know why

Answer 28

and also kids can't figure out what grade they got on a test without the teacher putting the percent on it which is crazy.

Answer 29

Luckily when I got a new teacher I told her I was confused and she took the time to explain and I got it but I guess that doesn't happen to most kids :(

Answer 30

It would be a better idea to say you get like a bonus on your grade if you can do the math to figure out what grade you got. It would give the kids more of a challenge

Answer 31

kids would call me a nerd for doing math and then would ask me to do their homework since I complete it in 5 minutes when it takes them 10 min.

Answer 32

Which I hate since what they say to me

Answer 33

hahahaha I enjoy doing math

Answer 34

if you call me a nerd and then ask me to do your homework. Would you think I would want to?

Answer 35

I hate algebra since the only time you would use it is to get honor roll

Answer 36

and people say they are smart and are in like 4th grade. I ask them what is PEMDAS. They say I don't know. Which I think is crazy

Answer 37

also if someone were to do a problem they would mess it up and that is what I hate about schools these days

Answer 38

We are losing in math

Answer 39

are avg. IQ has dropped by like approx. 10 points

Answer 40

insane!!!!!

Answer 41

I love math

Answer 42

but I just don't like the idea of people saying they are smart

Answer 43

Liam,there are ninth graders who struggle with add/subtract/mult/div for integers without a calculator

Answer 44

true

Answer 45

thanks to CCSS, BEDMAS/PEMDAS aren't even taught till like 5/6th at least not at a depth kids understand

Answer 46

cause they are afraid to be wrong

Answer 47

my mother made me learn multiplication in kindergarten which made me think

Answer 48

I had no clue though

Answer 49

no, they just don't know how cause they were handed a calculator in 3rd grade

Answer 50

they hate math since they don't think they are awarded and are always trapped inside

Answer 51

There is no such thing as a kid who can't do math. There is just a very obvious reflection of the education system failing many kids.

Answer 52

it would be better to have the math teacher be like a comedian

Answer 53

learned helplessness is a real issue.

Answer 54

cause it increases their time able to focus

Answer 55

Not necessarily comedian, but at least age appropriate material. If you give a 2nd grader abstract material, they aren't going to get it because their brain hasn't developed to there yet usually

Answer 56

true

Answer 57

not to mention the lack of recess in the k-5 school day... that is disgusting

Answer 58

yea and the punishments are crazy for kids who do nothing

Answer 59

you mean lack of punishment?

Answer 60

Liam, please keep this discussion focused and serious. If you've heard of PEMDDAS, you probably heard of it in the context of having to evaluate mathematical expressions. Please go back to wherever you learned PEMDAS, choose several problems to practice on, do the work and share your results here on OpenStudy for feedback.

Please let's not delve into "punishment," "kids do this or that," or the like, which are beside the point. Your learning will improve as your focus improves.

Answer 61

ok
