BODMAS.
is
BRACKETS then OF then DIVISION then MULTIPLICATION Then ADDITION then SUBTRACTION
8 / 2(2 + 2)
8 / 2(4)
8 / 8
= 1

LOL.
The brackets bind tighter than the division sign. It's a trick question.
What the 16 proponents are seeing is
(8/2) x (2+2)
(4) x (4)
(16)
What the brackets are doing though is
(8) / (2 x (2 +2))
(8) / (2 x 4)
(8) / (8)
(1)
- tedmiston 7y agoBut the extra set of parentheses added here in your reply is not part of the original equation: (8) / (2 x (2 +2)) ^ ^ I don't follow why you don't do the multiplication left to right after the expression inside the parentheses has been evaluated. Once the parentheses (PEMDAS) precedence has been applied to result in 8 / 2 * 4, then it should just be standard multiplication and division left to right, right? https://www.google.com/search?hl=en&q=%3D%208%20%2F%202%20(2%20%2B%202) https://www.google.com/search?hl=en&q=%3D%208%20%2F%202%20(2...
- simonblack 7y agoThe extra set of brackets is an attempt to show that the '2' in front of the bracket is shorthand for '2 x' i.e 2(...) = (2x(...)) but that '2' is part of the whole brackets expression and should be evaluated as such. As I mentioned before, this is really a trick question, and meant to be deliberately ambiguous.
