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?

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.

Young girl thought she found a lizard in the forest: When the vet sees it, he screams: “Stand back!”
In a remarkable twist of fate, a young girl stumbled upon a rare and endangered lizard in the depths of the forest, setting off an unprecedented chain of events that ultimately led to the preservation of an entire species. Millie, an avid lover of nature, stumbled upon the elusive black lizard during one of her solitary explorations in the woods. Initially hesitant, she couldn’t bear to leave the creature behind after noticing its ailing condition, prompting her to take it home for urgent veterinary care.
However, the veterinarian’s reaction upon seeing the lizard was nothing short of alarming, leaving Millie and her father bewildered and anxious. The vet’s sense of urgency, coupled with a subsequent phone call, hinted at the gravity of the situation, sparking fears of losing this precious creature. After an agonizing wait, the veterinarian returned with dire news: not only was the lizard incredibly rare, but it also belonged to a species teetering on the brink of extinction.
The lizard had managed to escape from a breeding program aimed at bolstering its dwindling population. Millie’s unexpected encounter and compassionate act of rescue inadvertently achieved a vital objective, ensuring the survival of an entire species. The veterinarian’s disclosure underscored the lizard’s pivotal role in conservation endeavors, underscoring the significance of Millie’s actions.
Though initially disheartened at the thought of parting ways with their newfound friend, Millie and her family acknowledged the lizard’s greater purpose. Their willingness to collaborate with authorities yielded promises of assistance, including educational opportunities and financial support.
This inspiring narrative serves as a poignant reminder of the potency of empathy and the profound influence that individual deeds can wield in wildlife preservation. Millie’s unwitting role in saving a species underscores the imperative of environmental stewardship and the potential for positive transformation, even amidst the most unexpected circumstances.
