Do you know the steps of the Order of Operations?

anonymous · Answer

$$PEDMAS$$

calculusxy · Answer

Well I believe that it is PEMDAS. You have to do Multiplication and Division left to right and Addition and Subtraction also .

anonymous · Answer

Still don't understand it

jigglypuff314 · Answer

PEMDAS
Parenthesis
Exponents
Multiplication/Division (left to right)
Addition/Subtraction   (left to right)

calculusxy · Answer

P for parenthesis
E for exponents
M for multiplication
D for division
A for addition
S for subtraction

*Multiplication and Division is done left to right. Meaning whatever is on the left do that one first.
*Addition and Subtraction is done left to right.

so you would do the stuff in the parenthesis first
( stuff )
so for    2 x (3 – 6) + 12
you would first do    3 - 6 = -( 6 - 3) = ?

calculusxy · Answer

Follow the orders of the operation and you will arrive with your answer. Don't worry, I will help you on answering this question.

@musa19965 What do you do first based on the PEMDAS?

@xionfairy
first of all, you're not supposed to give answers
second of all, you forgot a negative and so your answer is wrong...

calculusxy · Answer

$$2\times(3-6)+12$$
Based on this, do you see a parenthesis (since parenthesis is first in the Order of Operations)?

calculusxy · Answer

( ) These two symbols are parenthesis. Do you see this in any part of the equation?

shamil98 · Answer

2 x (3-6) + 12
you do the subtraction the parantheses first (3-6)
you then are left with
2 x (-3) + 12
then you do your multiplication.
2 x - 3 = -6
finally you are left with addition
-6 + 12, keep in mind this is the same as 
12 - 6 
your answer is 
6
