Are you ready to put your math skills to the test? The equation below may look simple at first glance, but don’t be fooled—it’s designed to challenge your ability to apply the correct mathematical rules.
The problem:
50 + 10 × 0 + 7 + 2 = ??
Take a moment to solve it in your head before reaching for a calculator. Do you have your answer? Let’s see if you got it right!
Common Mistakes People Make
Many people make errors when solving equations like this because they instinctively solve them from left to right. However, math isn’t always that straightforward.
One of the biggest pitfalls is ignoring the order of operations, which is a fundamental rule in mathematics. If you don’t follow the correct sequence, you might end up with the wrong answer—even if your basic arithmetic is correct.
Understanding the Order of Operations (PEMDAS)
To solve this equation properly, we must follow the order of operations, commonly remembered using the acronym PEMDAS:
- P: Parentheses
- E: Exponents
- MD: Multiplication and Division (from left to right)
- AS: Addition and Subtraction (from left to right)
According to PEMDAS, multiplication and division must always be performed before addition and subtraction, unless parentheses indicate otherwise.
Step-by-Step Breakdown of the Solution
Now, let’s break down the equation step by step using PEMDAS.
- Identify operations in the correct order
The equation is:
50 + 10 × 0 + 7 + 2Since multiplication comes before addition, we must solve 10 × 0 first. - Perform the multiplication
10 × 0 = 0Now, substitute the result back into the equation:
50 + 0 + 7 + 2 - Solve the remaining addition
- 50 + 0 = 50
- 50 + 7 = 57
- 57 + 2 = 59
Final Answer: 59
The correct answer to the equation 50 + 10 × 0 + 7 + 2 is 59.
Did You Get It Right?
If your answer was different, don’t worry! This type of problem tricks many people because our instinct is to solve it from left to right instead of following the order of operations. The key takeaway here is to always do multiplication before addition to ensure accuracy.
Why Mental Math Matters
