A seemingly straightforward arithmetic problem has taken the internet by storm, igniting debates and confusion among people worldwide. The problem appears simple at first glance, but its solution hinges on a crucial understanding of mathematical principles. Here’s the challenge:
50 + 10 x 0 + 7 + 2 = ??
To many, the equation looks like a basic addition and multiplication problem, but the varying answers highlight the importance of following the proper order of operations in mathematics. This simple equation has become a battleground for math enthusiasts and novices alike, each presenting their version of the correct answer.
The Order of Operations: PEMDAS/BODMAS
The primary reason for the discrepancy in answers lies in the order of operations, a fundamental concept in arithmetic. The order of operations is typically remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)) in the United States, or BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction) in other parts of the world.
Without adhering to this hierarchy, solving any mathematical equation can lead to incorrect results. Let’s break down the problem using the PEMDAS/BODMAS rules:
- Parentheses/Brackets: There are none in this equation.
- Exponents/Orders: There are none in this equation.
- Multiplication and Division: These operations come next and are performed from left to right.
- Addition and Subtraction: These operations are performed last, from left to right.
Step-by-Step Solution
Let’s apply the PEMDAS/BODMAS rules to the equation step-by-step:
50 + 10 x 0 + 7 + 2
- Multiplication first:
- 10 x 0 = 0
Now the equation is simplified to:
50 + 0 + 7 + 2
- Addition next:
- 50 + 0 = 50
- 50 + 7 = 57
- 57 + 2 = 59
Thus, the correct answer is 59.
Why the Confusion?
The confusion arises primarily from a misunderstanding or lack of familiarity with the order of operations. Some might solve the problem from left to right without considering the hierarchy of operations, leading to an incorrect result. For instance, if someone performs the addition before the multiplication, they might calculate:
50 + 10 = 60 60 x 0 = 0 0 + 7 = 7 7 + 2 = 9
This incorrect method leads to an answer of 9, which is far from the correct answer of 59. This example illustrates why it is critical to follow the order of operations to avoid errors.
Common Mistakes and Misconceptions
- Ignoring the Order of Operations: The most common mistake is to perform operations as they appear from left to right without following PEMDAS/BODMAS.
- Misunderstanding Multiplication by Zero: Some people might mistakenly think that because multiplication by zero yields zero, the entire equation becomes zero, which is incorrect.
- Overlooking Simple Arithmetic Rules: In the haste to solve the problem, basic arithmetic rules might be overlooked, leading to incorrect answers.
