Are you ready for a mental workout? Social media is buzzing with this latest math puzzle that has stumped even the sharpest minds. The challenge is simple to state but can be tricky to solve:
This puzzle requires you to tap into your mental math skills, forbidding the use of calculators or pen and paper. Grab a coffee, take a deep breath, and let’s dive into this numerical conundrum together!
When tackling math puzzles, a common error is neglecting the order of operations, a fundamental principle in arithmetic. Many rush to perform operations from left to right as they appear, leading to incorrect answers. This oversight often results from forgetting or misapplying the BODMAS/BIDMAS rule (Brackets, Orders (i.e., powers and square roots, etc.), Division and Multiplication, Addition and Subtraction), which dictates the sequence of operations to achieve the correct result.
To solve this puzzle correctly, follow these calculated steps:
- Identify the Operations: Look at the equation:
11 - 11 × 11 + 11. - Apply the BODMAS Rule: Start with multiplication before moving to addition and subtraction.
- Perform Multiplication:
- Multiply 11 by 11.
11 × 11 = 121.
- Proceed with Subtraction and Addition:
- Subtract 121 from 11 (the first number in the sequence).
11 - 121 = -110.- Then add the last 11.
-110 + 11 = -99.
- Confirm the Solution: The correct answer is
-99.
By multiplying first, you ensure that the scaling of the number is done correctly before reducing or increasing it through addition or subtraction. This method prevents the common mistake of sequential processing (left to right) without considering operation precedence, leading to accurate results.
Now it’s your turn! Try solving the puzzle again using the steps provided. Did you get -99 as your answer on the first go, or did the sequence of operations trip you up?
