# 48293 > 48÷2(9+3) is a 2011 viral math puzzle that divided the internet into two camps—those solving it as 288 and those as 2—exploiting ambiguity in order-of-operations interpretation. 48÷2(9+3) =? is a deliberately ambiguous math equation that split the internet into two warring camps: those who got 2 and those who got 288. First posted on a Texas message board in April 2011, the problem exploited a genuine gap in how people interpret the order of operations, sparking thousands of heated replies across dozens of forums within 48 hours. ## Origin On April 7th, 2011, a user named al_carl posted the equation to Hot Pursuit, a local Texas community message board[4]. He said his son had brought it home as homework the night before. Al_carl set up a poll with four answer choices: 2, 3.14, 219, and 288. The results split almost evenly, with 50 users choosing 2 and 55 choosing 288[4]. The thread drew 95 replies of increasingly heated arithmetic debate. - **Platform:** Hot Pursuit (Texas message board) - **Creator:** al_carl (original poster) - **Date:** 2011 ## Overview The equation 48÷2(9+3) looks like something a fifth-grader should be able to solve. That's exactly what makes it so effective as bait. The problem hinges on whether you treat the "2" next to the parentheses as implied multiplication (binding it tightly to the parenthetical expression) or as a separate operation that follows standard left-to-right processing after division[3]. Depending on your interpretation, you get either 2 or 288, and both answers have legitimate mathematical arguments behind them[4]. The real trick is that the equation is poorly written on purpose. Professional mathematicians would never leave this kind of ambiguity in their work[1]. But stripped of context and thrown onto a forum full of people who believe math always has one right answer, it becomes a perfect engine for generating arguments. ## How It Spread The equation jumped platforms fast. On the same day it appeared on Hot Pursuit, someone reposted it to the Bodybuilding.com forums, where it racked up more than 2,500 replies[4]. Also on April 7th, threads about the equation popped up on Physics Forums[6], Wall Street Oasis[2], MSU Red Cedar, Grass City, Tennis Warehouse, Inside MD Sports, and The Escapist[4]. That evening, the question landed on Yahoo! Answers, where user Phyxius Ænimus broke down both approaches and noted that sometimes math genuinely doesn't provide a single definitive answer[4]. By April 8th, the equation had spread to Sneaker Talk forums, Yahoo! Answers Australia, and DIY Mobile Audio[4]. The Michigan State 247sports board posted it with the explicit goal of watching "people on here call each other idiots"[8]. The Physics Forums thread noted that every forum discussing the problem was split roughly 50/50[6]. The Wall Street Oasis thread, revisited years later as a "Throwback Thursday" post, showed how the debate had legs. Even the site moderator Andy confessed he didn't want to read the whole thread and just guessed the answer was 2[2]. ## How to Use The 48÷2(9+3) format typically works as engagement bait. People commonly post the equation (or a similar ambiguous expression) to a social media platform or forum with a prompt like "Can you solve this?" or "Only 1 in 10 people get this right." The resulting comment war between the "2" camp and the "288" camp generates massive engagement. Variations include changing the numbers while preserving the structural ambiguity between implied multiplication and left-to-right division. The key ingredient is always an expression where implied multiplication sits next to the ÷ symbol without clarifying parentheses. ## Cultural Impact The 48÷2(9+3) debate contributed to a broader wave of viral math problems that flooded social media throughout the 2010s. Slate's 2013 coverage framed these equations as exploiting the same kinds of ambiguities that make word riddles work, drawing on interviews with social psychologists and math historians to explain why people get so emotionally invested in arithmetic[1]. The debate also exposed real gaps in math education. The fact that PEMDAS, a mnemonic drilled into millions of American students, doesn't actually resolve every equation challenged the popular belief that math is always black and white[1]. Several math educators used the viral equation as a teaching moment about the importance of clear notation and the limitations of mnemonics as mathematical rules[6]. ## Fun Facts - The original Hot Pursuit poll included 3.14 (pi) and 219 as joke answer options alongside the two real contenders[4]. - The Bodybuilding.com thread about the equation hit over 2,500 replies in a single day, making it one of the forum's most active non-fitness threads[4]. - WolframAlpha and Google's calculator both return 288, while many scientific calculators that handle implied multiplication return 2[4]. - The ÷ symbol (called an obelus) is so prone to causing confusion that ISO 80000-2 recommends against using it at all[5]. - A Math Stack Exchange contributor demonstrated that simply replacing the parenthetical with a variable changes the answer most people give, even though the math is identical[7]. ## Frequently Asked Questions ### What is 48÷2(9+3)? It's a viral math equation first posted online in April 2011 that produces two different answers (2 or 288) depending on how you interpret the order of operations[4]. ### Where did 48÷2(9+3) come from? User al_carl posted it to the Hot Pursuit Texas message board on April 7, 2011, saying his son brought it home as homework[4]. ### What does the 48÷2(9+3) debate mean? The equation exposes a genuine ambiguity in standard mathematical notation, specifically whether implied multiplication (writing "2(" without a × sign) takes precedence over division[3]. ### How do you use the 48÷2(9+3) meme? Post the equation (or a similar ambiguous expression) on social media and watch the comments fill with people arguing over the answer. It works as reliable engagement bait[1]. ### Is 48÷2(9+3) still popular? The specific equation is a classic piece of internet debate history. Similar ambiguous math problems still circulate regularly on social media as engagement bait[1]. ### Is the answer 2 or 288? Both answers are mathematically defensible depending on which conventions you follow. The real issue is that the equation is ambiguously written and would need additional parentheses to have a single clear answer[3]. ### Why do calculators give different answers? Different calculators implement the order of operations differently, especially regarding implied multiplication. Google and WolframAlpha return 288, while some scientific calculators that give implied multiplication higher priority return 2[4]. ### What is PEMDAS and why doesn't it solve this? PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction) is a mnemonic for the order of operations, but it's a convention, not a universal law. Many people misread it as meaning multiplication always comes before division, when the standard convention treats them as equal priority resolved left to right[1]. ### What is implied multiplication? It's when two expressions are written next to each other without an explicit × sign, like "2(12)" instead of "2×12." Some mathematical traditions give implied multiplication higher precedence than explicit multiplication or division[7]. ### Why do people get so angry about this equation? Social psychologist Robert Glenn Howard explains that people are primed for debate on forums, and math's reputation as purely objective makes disagreement feel personal. The audience pressure of social media makes people double down rather than reconsider[1]. ### What forums had the biggest debates about this? Bodybuilding.com generated over 2,500 replies, and the equation was simultaneously debated on Physics Forums, Wall Street Oasis, Yahoo! Answers, and dozens of other communities on the same day it was posted[4]. ## References 1. [Facebook math problem: Why PEMDAS doesn’t always give a clear answer.]() 2.
