I used the {} to signify a fraction, not as an extra pair of parenthesis. By mathematic definition, an operation is a function that takes 2 numbers in a specific order and yields one result. An operation can be delayed by the of parenthesis BEFORE the second number. Since the 2 is not wrapped in parenthesis, it is part of the division and since division and multiplication have equal precedence according to the order of operations, it would be done before the multiplication. there's no denying that the first operation done is the addition because of the parenthesis. Since there is no exponents, that brings us to multiplication AND division. They have EQUAL precedence, therefore it is computed from left to right. 6/2 =3, then 3*3 is 9.
