•8 ÷ 2 = 4
•4 × 4 = 16
This interpretation follows the conventional rule set taught in most classrooms.
Still, not everyone agrees.
Mike Breen from the American Mathematical Society explained: “the way it’s written, it’s ambiguous.”
While working with Popular Mechanics, he added: “In math, a lot of times there are ambiguities. Mathematicians try to make rules as precise as possible. According to strict order of operations, you’d get 16, but I wouldn’t hit someone on the wrist with a ruler if they said 1.”
Why Others Argue the Answer Is 1
Those on the other side approach the expression differently.
After solving 2 + 2, they treat the result as still being grouped with the 2, effectively interpreting the equation as:
8 ÷ 2(4)
