The correct answer is: 8/2(2+2)= 8/(2x2+2x2)= 8/(4+4)= 8/8= 1 (the implicit product must be resolved first, distributive can be used to solve the ambiguity) We cannot assume (8/2)x(2+2)= 4x4= 16 it is wrong because it separates the implicit multiplier 2 from the (2+2).
You are totally incorrect critiba. 8÷2×4, any grade 5 learner will tell you that the answer is 16. By using simple mathematical rules. You are saying 2×4 =8. But it is ÷2×4
According to the American Mathematical Council any expression as a/bc should be resolved as a/(bc) and not (a/b)c. The exemple is the Bhascara formulae: (-b+-SQRT(b²-4ac))/2a. Note that the 2a must be resolved first otherwise the result will be wrong.
@@harrymatabal8448 you would still need to multiply that by 1/4 if you are changing it to a multiplication. Or do people just not know how division groups things?
Lets just make it easy. !!! When we have these long and complicated equations we normally split it into segments. Splitting this terribly complicated equation into segments, is a method that is INCONTROVERTIBLE. [Look for explicit operators not enclosed in brackets, then put brackets around each segment.] This simplifies and clarifies these long and tedious equations. i.e. 8 / 2(2+2) -> [8] / [2(2+2)] Now we clearly see it is 8 / 8 = 1 For people who do not understand parenthesis, this avoids the silly question of what to do 1st. So now, anyone can understand.
@@MrGreensweightHist If I am wrong then (2*1+2*2) =/= 2(1+2). Skyscrapers collapse, bridges fall... But (2*1+2*2) = 2(1+2). Notice the equal sign. This means one expression can be substituted for the other.
@@Of_UnCommon_Sense You are wrong. Your hyperbole does not change that. 10/2(3) =15. But by your logic 10/2(3) = 2 Which means, by YOUR logic 10*0.5*3 = 2 Your way is inconsistent, and therefore not real math Engineers do not use math according to YOUR way.
@@MrGreensweightHist Once again you can get nothing right. 10 / 2(3) = 10 / 6 Its your logic that says its 10*0.5*3 = 2 And that expression = 15... not 2 So again you fail miserably. BTW where did you get 2.
@@MrGreensweightHist 10/2(3) would be 10/6 or 5/3 or 1 2/3 or 1.6666 10/2*3 isn’t the same as 10/2(3) this is because of how division works when put into an inline format works, 2(3) is a single term whereas 2*3 is two terms. Division has a vinculum which is also a grouping symbol and if you wanted it not to group things that would be grouped you out it in brackets like (10/2)(3) or use an explicit multiplication sign 10/2*3
So let's go all the way back to pre algebra. You should always check your work. Let's make this an equation so we can do so. 8÷2(2+2) = 8÷2(4). Let's have Y = 4 So, the equation is 8÷2(y)=16, according to you. 8÷2y=16 becomes 8/2y=16 Reduce 4/y=16 Simplify 4=16y simplify 4/16=y simplify 1/4=y Let's put the y back now. 1/4=4 this is obviously a false statement. Let's do this with 1. Y still equals 4. 8÷2(y)=1 simplify 8/2y=1 Reduce 4/y=1 which is y=4 4=4 is a true statement. This means the answer is indeed 1. PEMDAS isn't wrong. Everyone who is getting it wrong is skipping the most overlooked part of P (or B, depending). That is that the multiplier on the outside of the parenthesis (called the coefficient) is PART of the parenthesis. The distributive property is fundamental and can't be changed to make an argument work. Check your work.
Why u are making it so much hard and lengthy , it's very simple just the bodmas is required it solved it in my mind and got 16 and u went all way back to algebra
