20 / 5 (2*2) is and always will be 1
20 / 5 (2*2) do 2*2=4 first, then 5*4=20, then 20/20 =1
People who do this shit never actually look at reality.
If the teacher still thinks it's the same have her multiply her tax rate by 4 and see how much she believes that both answers are the same.
20 / 5 (2*2)
20 / 5 (4)
20 / 5 * 4
4 * 4
16
The answer is 16, 1 is wrong, after doing PEMDAS you go from left to right, multiplication and division are considered the same step, so you do them left to right
But it's pedmas
You must do parentheses first you can not divide first. In this instance multiplying into the parentheses and then divide
If anyone gets a 1 on this you might actually wanna go see a doctor.
Its Please Excuse My Dear Aunt Sally
But M/D are the same and A/S are the same
Isn't this an edit?
Ambiguous division is why you always write things as fractions
Both answers are correct depending on your interpretation on whether the 5 is attached to the 2×2 or not.
Spoken like a feminist
Bedmas, my dudes.
I'm out. Whole point of math is to get standardised so you don't end up fucking things up.
Introducing uncertainty is against the whole point of it in the first place.
no you dumb fuck, it is and always will be 16

20 / 5 * 4
20 / 20
1
You need to be retarded to think you have to do (2*2) first.
Division and multiplication have the same priority and you always start your operation left to right so the first step is 20 / 5 then (2 * 2) finally the multiplication of both results so
20 / 5 (2 * 2) = 4 (2 * 2) = 4 (4) = 16.
Fucking kill yourself uneducated piece of shit.
You are wrong my friend, you did it right to left for some reason, its supposed to be left to right for same level operations

But you do do 2*2 first, because it's in the parenthesis you dumb shit. It doesn't affect the answer in this case but you're still wrong.

>>> 20/5*(2*2)
16
Actually you start with anything in brackets, then its any division/multiplication in order from left to right.
P is Parentheses, you do anything in parens first dipshit
he didn't say to do the parentheses first, his mistake was that he didn't go from left to right

what the FUCK is this shit?

20 / 5 (2*2) == 80/5
just saiyan
its the ACTUAL and REAL math everyone worldwide uses
USA is just a meme at this point
The order is denoted here in the UK as:
B rackets
I ndices
D ivision
M ultiplication
A ddition
S ubtraction
The standard form is that we calculate the way that we read (in the west that is) i.e. Left to Right. Thus the correct calculation is:
20/5 first and then 2x2 thus:
(20/5)(2x2)=4x4=16
its caused by poor layout
imagine it as a more traditional fraction, is the (2*2) on the denominator or is it outside the the fraction?
>itt
yet another proof that all 'murrica is good about is breeding more and more retards
was taught as BODMAS but yea
well apparently
>math works different beyond the pond
Underrated
Where the fuck did you learn math?
20 / 5 (2*2)
20 / 5 (4)
4 (4)
16
>indices
>putting single number in brackets
>questioning anyones calculations
The question has 2 answers because its poorly formatted. Because its unclear whether (2x2) is in the denominator there isn't a certain answer. So all you faggots are right. SAUCE: googled that shit.
Jeeeeesus CHRRRRRIIIIST!!!! Our children are fucked. That's all this thread amounts to.
Today, this fucking idiot finally discovered what the 'P' means.
Is this a real photo?
There's only one way to do math
It doesn't care about the parentheses
yeah i had a calculator with a computer algebra system on it, had to be careful with adding paranthesese, changes the equation
Distribution before division faggot. Answer is 1 and only 1. Nothing else.
fuck off and kys

its easy
american leaders realised that utter imbeciles are easier to control and are making up "their own" mathematics so nobody will ever question low salary
How the fuck is it 1?
You do the brackets first, and then you do the multiplications/divisions from left to right.
= 16
