Are you ready to challenge your math skills with a deceptively tricky equation? Today’s puzzle, -8 – (3 – 8) × 2 = ?, might look simple at first glance, but don’t let its straightforward appearance fool you. Many stumble on problems like this due to overlooked details or forgotten math rules. Before diving into the solution, give it a try. What’s your answer? Let’s break it down step by step to ensure you not only solve it but truly understand the logic behind it.
Common Mistakes in Math Puzzles
Before tackling the problem, let’s address some common pitfalls that often trip people up with equations like this:
- Forgetting the Order of Operations
The biggest mistake people make is ignoring PEMDAS/BODMAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). This rule dictates the correct sequence for solving equations. - Misinterpreting Negative Numbers
Negative numbers can be tricky, especially when combined with subtraction or parentheses. Missteps in handling these can lead to wildly incorrect answers. - Skipping Steps
Trying to solve too quickly or mentally skipping intermediary steps can easily result in errors. - Overthinking
Sometimes, a seemingly simple problem causes people to second-guess themselves, leading to overcomplication.
Sound familiar? Don’t worry—these are all fixable. Let’s tackle this equation step by step.
Step-by-Step Solution to -8 – (3 – 8) × 2
Let’s solve the problem logically, following the proper order of operations.
Step 1: Resolve the Parentheses
The first step is to simplify everything inside the parentheses. In this case, we have:
3 – 8 = -5
So, the equation becomes:
-8 – (-5) × 2
Step 2: Perform the Multiplication
Next, handle the multiplication. According to PEMDAS, multiplication comes before subtraction. Multiply -5 × 2:
-5 × 2 = -10
Now substitute this result back into the equation:
-8 – (-10)
Step 3: Subtract the Negative Number
Here’s where many people falter—subtracting a negative number. Subtracting a negative is equivalent to adding the positive counterpart. So:
-8 – (-10) = -8 + 10
Step 4: Perform the Final Addition
Now, simply add the numbers:
-8 + 10 = 2
The correct answer is: 2.
Why This Puzzle Is Tricky
Even though the math itself is straightforward, this puzzle often stumps people. Why? Let’s break it down:
- Double Negatives
Subtracting a negative number isn’t something we encounter often, so it’s easy to forget that it converts into addition. - Order of Operations
Ignoring PEMDAS and solving the equation from left to right leads to errors. For example, some might incorrectly subtract -8 – 3 before handling the multiplication. - Mental Shortcuts
In a rush to solve, people might skip writing out intermediate steps, increasing the likelihood of mistakes.
Recognizing these common errors can help you approach similar problems with greater confidence.
