  • A seemingly simple math problem, 6 ÷ 3 x (5 + 2) = ?, has gone viral on social media, confusing many users.
  • The confusion arises from differing interpretations of the order of operations (PEMDAS/BODMAS).
  • Solving such problems can benefit cognitive functions like decision-making, logic, reasoning, and memory.

A basic mathematical calculation has become an internet sensation, baffling thousands of users across social media platforms. The problem, presented as 6 ÷ 3 x (5 + 2) = ?, has sparked widespread debate due to the varied and often conflicting answers users arrive at, each convinced of their own correctness.

The challenge went viral because many users obtained different results, convinced that their answer was correct.

— La NaciónExplaining the reason for the math problem's viral spread.

The core of the confusion lies in the application of the order of operations, commonly known by acronyms like PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) or BODMAS. This established hierarchy dictates the sequence in which mathematical operations must be performed to ensure a single, correct result. When this order is disregarded, even simple problems can lead to incorrect outcomes and heated online discussions.

The specific challenge in this calculation involves the sequence of multiplication and division. According to the standard order of operations, multiplication and division have equal precedence and are performed from left to right as they appear in the equation. In this case, the division (6 ÷ 3) should be performed first, followed by the multiplication by the result of the parentheses (5 + 2).

The essential rule for solving mixed mathematical operations is known as PEMDAS (for its acronym in English) or hierarchy of operations, which establishes the order in which the different parts of a calculation must be resolved.

Beyond being a mere brain teaser, engaging with mental calculations like this offers significant cognitive benefits. Research, including a study from Princeton University published in the Journal of Neuroscience, suggests that practicing math exercises strengthens brain areas associated with logic, reasoning, and memory. These cognitive workouts can enhance decision-making abilities and improve overall daily cognitive function.

Practicing mathematical calculations influences people's ability to make decisions, as each operation performed works key areas of the brain related to logic, reasoning, and memory.
