C
ANSWER HERE:
The answer is 6.
Let’s solve the expression step by step:
The expression is:
6 – 5 × 2 + 10
According to the order of operations (PEMDAS/BODMAS):
Multiplication first:
5×2=10
Now the expression is:
6 – 10 + 10
Left to right (addition and subtraction):
6−10=−4
−4+10=6
Final Answer: 6
Do you think you can solve this tough math puzzle?
Math puzzles are more than just numbers on a page—they’re a challenge that gets your brain working, a riddle that begs to be solved.
The satisfaction of cracking a tricky equation is unmatched, especially when it’s a problem that seems simple at first glance but reveals itself to be more complex.
Today, we’re diving into one such puzzle that’s been causing quite a stir:
Before you jump to conclusions, let’s explore how to approach this deceptively simple math puzzle.
A

C
ANSWER:
To solve this puzzle correctly, we need to remember the order of operations, often remembered by the acronym PEMDAS:
Parentheses
Exponents
Multiplication and Division (from left to right)
Addition and Subtraction (from left to right)
So, let’s apply PEMDAS to our equation.
Step-by-Step Solution: Applying PEMDAS
Step 1: Identify Operations
First, we identify the operations in the equation: addition and multiplication. According to PEMDAS, multiplication comes before addition.
Step 2: Perform Multiplication First
We start by performing the multiplication: 7×8=56.
Step 3: Substitute Back Into the Equation
Now, substitute 56 back into the original equation: 6+56+9
Step 4: Perform the Addition
Next, we perform the addition from left to right: 6+56=62, 62+9=71.
Final Answer: 71
So, the correct answer to the puzzle is 71.

Quizzes are often associated with classrooms and game shows, but their benefits extend far beyond entertainment or academic assessment. They are powerful tools that can enhance brain function, improve memory, and promote lifelong learning. Recent research in cognitive psychology and neuroscience highlights the positive effects of quizzing on brain health and intellectual development.
One of the most significant benefits of quizzes is the testing effect. This phenomenon suggests that retrieving information from memory, as one does during a quiz, strengthens that memory more than simply re-studying the information. When individuals actively recall facts or concepts, neural connections associated with that knowledge become more robust. This improves long-term retention and makes it easier to retrieve the information in the future. In short, quizzing reinforces learning in a way that passive review does not.
Quizzes also encourage active learning. Unlike reading or listening, taking a quiz requires the learner to engage with the material, think critically, and apply knowledge. This active engagement helps the brain encode information more deeply. As a result, learners are more likely to understand and remember the content, rather than merely memorize it.
Additionally, quizzes enhance metacognition, or the awareness of one’s own knowledge and thought processes. When individuals take a quiz, they receive feedback—either immediately or afterward—that helps them evaluate what they know and what they still need to learn. This process fosters self-awareness and helps learners adjust their study strategies for more effective outcomes. Knowing which areas are weak or strong allows for targeted practice, which is crucial for skill development.
Regular quizzing can also improve attention and focus. When people expect to be tested, they are more likely to concentrate during the learning phase. This heightened attention boosts the quality of learning and helps prevent the common problem of mind-wandering. Over time, the habit of focusing in preparation for quizzes can lead to improved concentration in other areas of life as well.
Beyond the cognitive benefits, quizzes also provide emotional and motivational advantages. They offer a sense of achievement, especially when learners see progress over time. This can increase motivation, reduce anxiety around testing, and build confidence in one’s abilities. Quizzes with gamified elements, such as points or levels, can also make learning more enjoyable and engaging.
From a neurological perspective, the brain thrives on challenge and novelty—two key features of well-designed quizzes. They stimulate the brain’s reward system by offering immediate feedback and small successes, keeping the learner mentally engaged. Furthermore, regular mental challenges such as quizzes are associated with a reduced risk of cognitive decline as people age, suggesting they may even contribute to brain health over the long term.
In conclusion, quizzes are far more than academic exercises. They are dynamic cognitive tools that reinforce memory, encourage active engagement, sharpen focus, and promote self-awareness. Whether used in schools, professional training, or self-study, quizzes play a vital role in enhancing learning and maintaining a healthy, active brain.
