Social media is buzzing once again with a seemingly simple math equation that’s tripping up adults everywhere. At first glance, it looks like elementary school arithmetic, but don’t be fooled—this puzzle has sparked heated debates online and left thousands of people with the wrong answer.
Here’s the equation:
50 + 50 − 25 × 0 + 2 + 2
The challenge is simple: solve it in your head without using a calculator.
The Trap: Why People Get It Wrong
Many people make the same mistake. They instinctively solve the equation from left to right, just as they would read a sentence. Doing so often leads to incorrect answers like 0, 4, or other unexpected results.
The problem isn’t the math—it’s forgetting one of the most important rules of arithmetic: the order of operations.
The Solution: Mastering the Order of Operations
To solve this equation correctly, you need to follow the order of operations, commonly known as PEMDAS or BODMAS. According to this rule, multiplication and division must always be completed before addition and subtraction.
Let’s solve it step by step.
Step 1: Perform the Multiplication
Focus on this part first:
25 × 0 = 0
Since any number multiplied by zero equals zero, the equation now becomes:
50 + 50 − 0 + 2 + 2
Step 2: Solve from Left to Right
Now complete the remaining operations:
- 50 + 50 = 100
- 100 − 0 = 100
- 100 + 2 = 102
- 102 + 2 = 104
The Final Answer
104
If you got 104, congratulations—you remembered the correct order of operations.
Why Does This Matter?
Puzzles like this are entertaining, but they also remind us how easily our brains can fall into familiar habits. Even simple-looking equations can become tricky when we rush or forget basic mathematical rules.
They’re a fun way to sharpen your thinking, test your attention to detail, and revisit concepts many of us learned years ago.
So, did you solve it correctly on your first attempt, or did the multiplication by zero catch you off guard? Share this puzzle with your friends and see who gets the right answer without using a calculator.
