After all, there are, in fact, two correct answers: 1 or 16. Mike Breen, a spokesman for the American Mathematical Society, explained why the equation solution generates so many differences: As it is written, ambiguous. In mathematics, there are often ambiguities. Mathematicians try to make rules as accurate as possible, he told the expert site Popular Mechanics.
He points out that the way a person has learned crucial mathematics to solve this problem, since there are two methods of resolution:
The methods differ only in order of multiplication and division. In this way, a PEMDAS fan would reach number 1, while one by the BODMAS method would get 16 in response.
