If you calculated 104, congratulations! You got it right.
If you got a different number, don’t worry. Let’s break it down step by step.
Step-by-Step Solution: How to Solve the Math Puzzle
To solve this equation correctly, we need to follow the standard order of operations, commonly remembered in the United States as PEMDAS.
PEMDAS stands for:
- P: Parentheses
- E: Exponents
- M: Multiplication
- D: Division
- A: Addition
- S: Subtraction
First, perform the multiplication:
25 × 0 = 0
Now the original equation becomes:
50 + 50 − 0 + 2 + 2
Next, complete the addition and subtraction from left to right:
50 + 50 = 100
100 − 0 = 100
100 + 2 + 2 = 104
Final Answer: 104
Why Do So Many People Get This Math Question Wrong?
The equation looks easy, but the multiplication by zero can confuse people who rush through the numbers.
One common mistake is performing every operation from left to right without considering multiplication first.
Remember that multiplication and division have priority over addition and subtraction. When operations have the same priority, work from left to right.
Taking a few extra seconds to follow the correct order can make all the difference!
