I don't think that's correct. When using PEMDAS it depends which comes first from left to right when it comes to multiplication and division. Its the same rule for addition and subtraction.
So it should be
8/2(2+2)
Let's rewrite this to make it easier
8÷2(2+2)
So first baracts( those are parentheses though) so we get 4
8÷2×4
Now it when doing this part it depends which comes first from left to write and since division comes first we do that. So that will be 4
Now we have 4×4
Which equals 16
sorry this is long, I just like math
....but it is math. More specifically, it's algebra.
I think it depends on the question itself. To be honest.. I see two different side of this question.
This is the question right. 8/2(2+2)
So, I see it like this.
1. (8/2)(2+2)
= (8/2)(4)
=(4)(4)
=16
2. 8/[2(2+2)]
=8/[2(4)]
=8/8
=1
To me. The bracket itself plays an important role in any type of mathematical equations. That's why it's important to state clearly either its multiple for the denominator or the whole set of fraction itself.
So yes, brackets are hella important.
I had to do a double take, and you're right. To solve the problem you need to find out whether 2 is "attached" to the 8 by division or the (2+2) by multiplication. It's all fucked up.
Can I say calculators don’t do bidmas also it’s literally yr7 maths your not meant to divide by 2 with the 8 the 8 is used last soooo u need to do brackets so 4 then u do 4x2 which gets u to 8 now the equation is 8/8 which is equal to 1 so that’s the answer literally this question came in my test paper ppl who put 16 down got 0 ppl who put 1 down got 2 marks sooooo
it is a 100% 16. Mathematicians agree that it is insanely stupid to not have two brackets as it just causes confusion. Still, following the rules of math it is 16, as you end up with 8/2*4. Multiplying does not precede dividing, like it does with addition or subtraction. You just go from left to right and the (2+2) is here just to make it look more fancy.
Yah, this
Okay so I just saw that America is in discussion about how to solve this:
8/2(2+2)
IT'S NOT 'EITHER 16 OR 1'
IT'S 1
1
DON'T YOU KNOW THE MATH RULES??????
Here's the rules of math, the top needs to be solved first, the bottom last, if there's 2 of the same kind, from right to left:
Being=brackets
Pioneer=powers
Made=multiplication
Darwin=division
A=addition
Scientist=substraction
((I know it makes no sense, but it's easy to remember so whatever))
SO
2+2=4
2×4=8
8/8=1
There you go, peeps.
Spread the knowledge.
