Viral Math Problem Sparks Debate

The internet is full of conundrums that spark debates, similar to the infamous blue and black dress that confused many. A viral math problem, 8 ÷ 2(2 + 2), posted on Twitter in 2019, created a similar stir, leaving people puzzled and arguing over the correct answer.

The Problem and the Debate

In 2019, a Twitter user posted a photo asking followers to solve the controversial math problem: 8 ÷ 2(2 + 2). This simple equation led to a massive debate across social media platforms.

Editors at Popular Mechanics, a lifestyle magazine, found themselves divided. In their workplace chat, they discussed and debated the correct answer. One editor explained that according to the “PEMDAS” rule (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction), the equation should be solved in the order of operations.

The Two Interpretations

First Interpretation: Following PEMDAS, they solved the parentheses first: 2 + 2 = 4. This simplified the equation to 8 ÷ 2 x 4. According to this method, you perform the division first: 8 ÷ 2 = 4, leaving 4 x 4, which equals 16.

Second Interpretation: Others argued for a different interpretation of PEMDAS. They also solved the parentheses first but treated the result as still within the parentheses: 8 ÷ 2(4). They believed that multiplication inside the parentheses should take precedence, giving 8 ÷ (2 x 4), which equals 8 ÷ 8, resulting in 1.

Expert Opinions

Mathematicians and scientists joined the debate. Mike Breen from the American Mathematical Society explained that, according to strict order of operations, the answer should be 16. However, he admitted that the equation is ambiguous in its written form.

Physics Professor Rhett Allain from Southeastern Louisiana University suggested that the question should have been written more clearly as 8/(2*(2+2)), which simplifies to 8/(2*4) and results in 1.

Conclusion

The viral math problem highlights the importance of clarity in mathematical notation. Despite expert opinions leaning towards 16, the ambiguity of the equation has left many unconvinced. What do you think is the correct answer to the equation? Is it 1 or 16? Let us know and share this debate with your friends and family to see what they think!
