A seemingly straightforward maths puzzle has taken the internet by storm, leaving a trail of confusion and debate in its wake. The brain teaser, which began circulating on social media this week, challenges users to solve a simple-looking equation: 10 ÷ 10 + 3 x 3.
The Viral Equation Causing Online Debate
Shared widely on X (formerly Twitter) by user @BholanathDutta, the puzzle has sparked significant discussion. At first glance, the equation appears elementary, using only three operations: division, multiplication, and addition. However, the simplicity is deceptive. The key to unlocking the correct answer lies not in solving from left to right, but in applying the strict order of operations.
Many who attempted the puzzle fell into the common trap of reading it like a sentence, leading to incorrect answers such as 12 or even 100. This approach highlights a widespread forgetfulness of fundamental mathematical rules taught in school. Can you beat the clock and solve it correctly in under 30 seconds?
The Secret Weapon: Remembering PEMDAS
For those struggling, the solution hinges on a crucial acronym: PEMDAS. Standing for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction, PEMDAS is the mathematical GPS that guides you to the correct destination. It dictates the sequence in which you must perform operations in any given equation.
In this specific puzzle, there are no parentheses or exponents, so priority immediately goes to multiplication and division. It's vital to remember that multiplication and division hold equal weight and should be performed from left to right, followed by addition and subtraction.
Breaking Down the Solution Step-by-Step
Let's apply the PEMDAS rule to crack the code of 10 ÷ 10 + 3 x 3.
First, we identify and execute the multiplication: 3 x 3 = 9.
Next, we perform the division: 10 ÷ 10 = 1.
Finally, we carry out the addition with our results: 1 + 9 = 10.
Therefore, the correct answer to the viral puzzle is 10. This methodical approach, following the established order of operations, is the only way to arrive at the right solution.
Why This Simple Puzzle Captured Everyone's Attention
This brain teaser's popularity underscores a fascinating aspect of online culture: the appeal of a shared intellectual challenge. It serves as a quick mental workout and a reminder of lessons from our school days. The widespread incorrect guesses demonstrate how easily these foundational rules can be forgotten without regular use.
So, the next time you encounter a similar puzzle, remember your mathematical GPS. Don't get lost by solving left to right; let PEMDAS guide your way to the correct answer every time.
