Order of Operations!

[Uncle Sam Eagle]

Yes, this is my 2nd favorite thing in math...(no. 1 is variables)

Ok here we go!


Here's an Order of Operations problem:
[(2 + 3) - 4] X 2

To do this to get the RIGHT awnser...remember the order like this:

PEDMAS

or

Please Exuse My Dear Aunt Sally

The reason why they are in bold..is that it is telling you the order.

now, heres the order!

1.Parentheses (Or the () symbols) Anything within parentheses must be done first no matter what it contains!

2.Brackets (Or the [] symbols) must be don AFTER parentheses! no matter what it contains!

3.Multiplicaton(if a number is right next to a problem that includes parentheses, multiply.)

4.Division

5.Addition

6.Subtraction

Now, practice Order of Operations! Do the work on a piece of paper if you have to, but no Calculator!

Here's a sample of how it looks like when the awnser is given.

2 + 3 - 6(5 + 2)
2 + 3 - 6*7
2 + 40-42
42 - 42
0

your reminding me of my Math teacher to much

get your mind on somthing else quickly!

[DeRailer]

everyone should know what PEMDAS is

"1.Parentheses (Or the () symbols) Anything within parentheses must be done first no matter what it contains!

2.Brackets (Or the [] symbols) must be don AFTER parentheses! no matter what it contains! "

Actually, parentheses and brackets have the same importance order. The only reason for using brackets is formatting, so that you don't lose track of your grouping by using only parentheses.

Until you get into domains and ranges, in which case a parentheses or bracket would indicate whether the upper/lower bound is an open or closed bound... but that's not with operations, so it doesn't matter.

[Hypersolidsnake]

Whoa... In canadian, it's BEDMAS

Brackets
Exponents
Divis/Multi
Add/sUbt

[DeRailer]

Does it have an easy way to remember it like PEMDAS does

[theryman]

thats how i learned it, also, vag. where do u live?

[ToKillAnATTICUS]

Hahaha1234, you need to edit your post, you spelled PEDMAS. ;) I like Algebra, but long division and fractions aint my thang

[Freddy]

Whoa... In canadian, it's BEDMAS

Brackets
Exponents
Divis/Multi
Add/sUbt

its the same thing

perenthasees(or bracket, same thing)
exponent
multi
divide
add
subt

[DeRailer]

maybe in canada they dont use parethesees

[kevinok]

There names for the same thing.

[DeRailer]

they dont look the same though

[Liokae]

They only serve the same purpose with regards to order of operations. In most other uses, the difference between a bracket and a parenthesis is extremely important.

[Hypersolidsnake]

I just remember BEDMAS as you know, like the Mass of my Bed... I actually was away the first day my class learned BEDMAS, so I HAD NO IDEA what they were talknig about when I got back... and I got back on a test day... Lucky me!

[kevinok]

That is a great story.

[DeRailer]

yes you were very lucky to get back on that day

[Vagrant]

Hahaha, you missed something... exponents

[Hypersolidsnake]

Who, me? I included them in my BEDMAS post... Must be talking to someone else, then.

[Vagrant]

hahaha, that's who.... doy

[Leperkawn]

I live in the USA and I use BEDMAS....

You forgot to add in to do the multiplication and divison and addition and subtraction from left to right.

[FrenziedEye]

Isn't it BODMAS? neva heard of that other one... anyway..order of operations is pretty simple...i bet most ppl in the forums would kno it pretty well..

[Vagrant]

PEMDAS for where I live...

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

[i_like_penguins]

on of my math teacher tought me beodmas

Brackets (or parenthesis)

Exponents

Of (changing the word of to * like 1/2*4=Y it goes to 0.5*4=2)

Division

Multiplication

Addition;and

Subtraction
