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.

The Tragic Reason Why One Man Actually Turned Blue Forever
The world’s most famous blue man, Paul Karason, also dubbed Papa Smurf, was born as a fair-skinned, freckled boy with ginger hair. In the 2000s, he became an internet sensation and made many TV appearances, openly talking about his condition. Let’s find out together why Karason turned blue and how he became a cautionary tale.
Paul Karason had a skin condition that made his skin flake, as well as acid reflux and arthritis. Doing his own research in order to improve these ailments, he found out about a solution of silver in water, also known as colloidal silver.
Colloidal silver was widely used as an antibiotic back before penicillin was invented in the 1930s. It was banned in 1999 in over-the-counter medications after scientists found that it can severely damage internal organs.

Karason drank what he believed was a miracle cure for over 10 years. Moreover, he even began to apply a silver preparation directly to his skin; he claimed his acid reflux and arthritis just went away. “I had arthritis in my shoulders so bad I couldn’t pull a T-shirt off. And the next thing I knew, it was just gone,” he shared.
Due to the silver accumulation in his skin, he started to turn blue and suffered from a permanent and rare condition called argyria. Only when Karason met an old friend who asked him, “What have you done to yourself?” did he begin to realize he’d become blue.
Karason claimed his blue skin had many advantages — he never got sunburns or had to wear sunglasses. There were some side effects he did not appreciate, however, such as folks “being less than polite” to him. Moreover, Karason confessed he couldn’t get a job because of employers’ resistance to hiring “people that are blue or that are noticeably different.”
Sadly, Paul Karason passed away in 2013 when he was 62 years old due to heart complications.
Papa Smurf’s story serves as a valuable lesson about the importance of being careful when it comes to at-home remedies. While it’s natural to want to find easy solutions to health problems, it’s important to be aware that such remedies can sometimes pose serious risks. It’s always better to consult a doctor and follow their advice for a safe and effective treatment.
