Have you ever seen a math problem that instantly splits the internet into two opposing camps?
This viral math puzzle is one of the most famous examples of such a debate.
At first glance, it looks like a simple arithmetic problem that any primary school student can solve.
However, millions of people around the world keep arguing over whether the correct answer is 1 or 16.
Let us break down the logic step by step to find the absolute truth behind this classic equation.
To solve any mathematical expression with multiple operations, we must follow the standard Order of Operations.
In mathematics, this fundamental rule is widely known by the acronym PEMDAS or BODMAS.
These rules guide us on which operation to perform first so everyone gets the exact same result.
The letter ‘P’ or ‘B’ stands for Parentheses or Brackets, which always take the highest priority.
Therefore, our very first step is to evaluate the numbers located inside the parentheses: (2 + 2).
Adding two and two together gives us four.
Now, we can substitute this result back into our original equation.
The expression now simplifies to 8 ÷ 2(4).
This is the exact point where most people get confused and make a fatal mistake.
The notation 2(4) simply means multiplication, which can also be written as 2 × 4.
So, our updated math problem becomes 8 ÷ 2 × 4.
Many people mistakenly believe that multiplication should always be calculated before division.
They multiply 2 by 4 first to get 8, and then divide 8 by 8 to reach an answer of 1.
However, in the standard order of operations, Multiplication and Division hold equal priority.
When operations of the same priority appear together, the strict rule is to calculate them from left to right.
Looking at 8 ÷ 2 × 4 from left to right, the division comes first.
First, we perform 8 ÷ 2, which equals 4.
Next, we take that result and multiply it by the remaining number: 4 × 4.
Multiplying four by four gives us sixteen.
Therefore, following the universal rules of logic and mathematics, the correct answer is 16!
