Why 8 Divided by 2 Is Breaking the Internet Again: the Math Problem Nobody Can Agree On
By Robert Thorne
Q1: Is the correct answer 16 or 1?
Under strict modern conventions taught in secondary education, the answer is 16 because division and multiplication share equal priority and are evaluated left to right. However, historical publishing standards and older algebraic parsing traditions treat implied multiplication as binding, which produces 1. Because the expression lacks clear grouping symbols, both interpretations stem from recognized operational rules.
Q2: Why doesn't PEMDAS mean multiplication comes before division?
PEMDAS is an acronym, not a strict linear hierarchy. Multiplication and division exist on the exact same tier of operational precedence. When both appear in a single expression without explicit brackets dictating otherwise, they are resolved sequentially from left to right.
Q3: How do computer programming languages handle 8÷2(2+2)?
Most modern programming languages, including Python, C++, and JavaScript, do not allow implied multiplication at all. Typing 8 / 2(2 + 2) triggers a syntax error. A programmer must explicitly write 8 / 2 * (2 + 2), which strictly follows standard operator precedence from left to right and evaluates to 16.0.
