Math problems are usually straightforward, but a seemingly simple equation from 2019 has sparked heated debates. Posted on Twitter, the problem divided people over the correct solution. What should have been an easy task left even the editors at Popular Mechanics split.
The equation, 8÷2(2+2), looks simple enough. Using PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)—the standard order of operations—the solution begins with solving inside the parentheses: 2+2 equals 4.
This simplifies the equation to 8÷2×4. Multiplication and division are treated equally, so you solve from left to right. First, divide 8 by 2, which gives 4, and then multiply by 4. The final answer is 16.
Despite this straightforward approach, others argue PEMDAS should strictly prioritize division over multiplication. This alternate interpretation fuels the debate, with some arriving at a different answer.
For now, 16 is widely accepted as correct, but the ongoing discussion highlights how interpretations of mathematical rules can cause even experts to disagree. Until a math genius settles the argument, the debate is far from over!
