    No wonder we have more cars on the road than needed when half the ppl are giving an answer 16 times the correct one!

      The only accurate answer to that math problem is "problem incorrectly stated". Whether the bracket is dividing or multiplying number 8 is unclear as the wrong division sign is used. There's no place for such ambiguity in math. You need to us / and then add a * before the bracket if the answer is supposed to be 16, or just use / if the answer is supposed to be 1. But never ÷ in any math problem statement involving more than two numbers. Basic stuff.

          According to the majority, it's 16.
          According to what people say here, it's 1.
          Because in 8÷2(2+2) you do the brackets first. Which gives 8÷2(4). Then, you multiply 2 with 4 because of the brackets which gives 8÷8. When is 1.

          Edit: BODMAS starts with Brackets and that means Brackets go first
          And what I was taught is that although brackets do the same thing as multiplication, they aren't the same because brackets go first.

            8:2(4) is 16 because you have to start from the left. So you have to do the division first

              First is (2+2) = 4
              Second 8 ÷ 2 = 4
              Third is 4 x 4 = 16

                  So like I'm not American and I havent been taught with bedmas or whatever
                  Just brakets, then divisions and multiplicacions from left to right and then adding and substracting from left to right
                  If you have 1x2/2 yo do 1x2 first, if you have 1/2x2 you do 1/2 first
                  So 8/2(2+2) its obviously 16
                  I don't get why theres debate

                    either youre trolling, or you really dont know the answer:
                    Since there is nothing between the 2 and the bracket you have to add a multiplication sign changing the problem to:
                    this turns out to be 8/8=1
                    The 2* has to be multiplied to both the 2's in the bracket.

                                    When it says let's say, 2 (4), it means 2×4. When there is 1 number in a bracket, you dont solve it as if it's a bracket. You consider it being multiplied.

                                    So, 8÷2(2+2) is
                                    Then we solve the brackets, (2+2)= 4

                                    And then we multiply, 4(4)=16

                                      Suppose you have the equations x = a/bc and you also know c = d+e. If you believe the answer is 1, you can substitute for c and end up with x = a/b(d+e). If you believe the answer is 16 you can't. The act of substituting for c changes the result. You end up with two equations which should be equivalent but aren't. Maybe I'm missing something, but that doesn't sound right to me. You shouldn't be able to break algebra that easily!

                                          8÷2*4 is not same as 8÷2(4). You always solve for Bracket/Parranethesis first. No Matter what system you are using(i.e BODMAS, PEMDAS).

                                          A Bracket/Parranethesis is not considered solved unless you eliminate it from the equation. It's is not eliminated by simply Replacing it with a × sigh. It is eliminated by performing the action. In this case 2(4) = 8.

                                            you do the brackets first, 2+2=4 then you do the 8 divided by 2 which is 4 and you multiply the 4 from the first half with the 4 from the half in the brackets giving you 16... that's how i was taught it

                                                      The answer is 1. There is no other way to resolve that. You always resolve any fractions, parenthesis etc. Each side of the main equation before resolving it.

                                                        Isn’t the brackets just the simplification of the original equation? So the answer is 4? Im probably wrong but meh.

                                                          Brackets show what you should do first, or give priority to a part of an equation.
                                                          For example: 8 ÷ 2(2 + 2)
                                                          In this example, you have to do 2 + 2 first, then the rest from the order of left to right.
                                                          That is:
                                                          8 ÷ 2 (2 + 2) =
                                                          8 ÷ 2 • 4 =
                                                          4 • 4 = 16.

                                                        So I understand how people can get 16 but the thing is in mathematics you can just put it in a calculator and get the answer it's step by step. When you put it in a calculator in whole it will divide 8 with 2 first before timing it with 4. The proper way is to times the 2 with 4 first because 2(n) is 2 times (n) since it should be split from divide beforehand.

                                                                Am I the only one who had to learn BEDMAS for computer, BODMAS for maths and BIDMAS for mental ability problems?

So which is correct? As it results in two different sets of answer: 16 and 1.
