Challenge: Can you solve this math problem for middle schoolers – without a calculator?
Classic brain training methods are perhaps puzzles like crosswords or sudoku, but I have recently become more attracted to the type of challenge you’ll see below.
These puzzles have been flooding the web lately, probably because they are really fun!
These are old classic mathematical problems. When you were in middle or high school.
These math problems are more fun when you find yourself trying to remember the math you learned as a child.
Can you figure out the correct solution?
Here is the challenge, in the picture below.
At the top of the picture, we see the task and then four possible answers.
Which solution do you think is the correct one?
How did you come up with it?
Take your time and think about it to find the correct solution.
Done? Below you can check if you picked the right number!
A
B
C
The correct answer
The correct answer is B: 12.
Why is 12 the correct answer?
Well, if you remember from your school days, according to the order of operations, you do multiplication before addition and subtraction, so you start by solving 3 x 3, which results in 9.
Then we are left with a simpler math problem: 3 + 9 – 3 + 3
The answer is therefore 12.

I’M 74 AND ADOPTED A GERMAN SHEPHERD WHOSE OWNERS WANTED TO EUTHANIZE.
The phone call came unexpectedly, my son’s voice laced with concern. “Mom,” he said, “you won’t believe this. There’s a beautiful German Shepherd at the shelter, and they were about to euthanize him!” My heart sank. How could anyone even consider such a thing?
He explained that the young couple who brought him in, the ones who had raised him from a puppy, were moving and simply couldn’t “handle a big dog anymore.” The thought of them discarding Hunter like a piece of unwanted furniture filled me with a rage I hadn’t felt in years.
“I’ll take him,” I declared, my voice firm.
“Mom,” my son hesitated, “He’s a big dog. Are you sure you can handle him? You’re not getting any younger.”
“I’ve had big dogs before,” I retorted, my voice rising. “And besides, I’m not going to let some irresponsible people decide his fate.”
The next day, I drove to the shelter, my heart pounding. The sight of Hunter, standing forlornly in his kennel, almost broke my heart. He was magnificent, with a thick, jet-black coat and eyes that held a hint of sadness. As I approached, he whined softly, his tail thumping against the kennel wall.
From the moment I stepped into his kennel, I knew he was meant to be mine. He nuzzled my hand, his fur soft against my skin, and I felt an instant connection. The shelter staff assured me he was well-behaved and gentle, and I knew it was true. I took him home that day, a wave of relief washing over me.
Life with Hunter has been a joy. He follows me everywhere, his presence a constant comfort. He curls up at my feet during the day, his head resting on my lap, and sleeps soundly beside my bed at night, a watchful guardian. He’s a gentle giant, never once causing any trouble. He’s the best listener, patiently enduring my rambling stories and offering silent companionship.
Sometimes, I catch him watching me, his golden eyes filled with a deep affection that melts my heart. I know he knows he was rescued, that he understands he has a home now, a safe haven. And in those moments, I feel a profound sense of gratitude.
Hunter has brought a renewed sense of purpose to my life. He’s taught me about unconditional love, about the importance of giving back, and about the resilience of the human-animal bond. He’s a reminder that even in the darkest of times, there is always hope, always a chance for redemption. And most importantly, he’s my family now, and I will never let him go.
This story emphasizes the emotional connection between humans and their pets, highlighting themes of rescue, companionship, and the importance of providing a loving home for animals in need.
