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.

Woman leaves an empty seat for her late son on her wedding day – She can’t believe it when she sees an unknown person sitting in the chair…

Life is unpredictable. Sometimes, no matter how hard we try to make things right, God has other plans.
Becky is a woman who tragically lost her son Tristan, who was just 19 years old at the time he left this world. Her grief was immense. She couldn’t possibly imagine her life without her child, but over time, her loved ones helped her accept the reality and move on.
Around two years after Tristan’s passing, Becky was about to marry the love of her life, a man named Kelly.

On the day of their wedding, the two decided to leave an empty seat in Tristan’s honor with a heartwarming message written on it. “What should I do now that I’ve arrived in heaven for your wedding? I will stoop to your level in order to spend it with you. Please save me a seat, even if there is only one available chair. Although you might not notice me, I shall be present.”

As the ceremony proceeded, Kelly informed Becky that there was someone there who wanted to see her. A young man who took Tristan’s chair. When she saw him, Becky wasn’t mad. On the contrary, spotting the young man, she was overwhelmed and couldn’t stop tears from rolling down her face.

That man, Jacob, was the recipient of Tristan’s heart. Tristan was an organ donor, and Jacob wasn’t the only person whose life he saved.

When Kelly informed Jacob that he and Becky are getting married and invited him to the ceremony, Jacob was more than willing to travel from San Diego in order to attend it. It was a beautiful surprise that warmed Becky’s heart and made her day. She felt like her son was present on her wedding day.

Becky was then given a stethoscope so that she could hear her late son’s heartbeat. It was an emotional moment no one could ever forget.

Someone snapped photos of the beautiful surprise and shared it on Facebook. The story went viral in a matter of days and many praised Kelly for his love for Becky.

Many people took their time to comment, with one person writing: “Why is it that we can’t just have one news channel that is dedicated to delivering uplifting and motivational stories like this one? If only the goodness and thoughtfulness that exists in the world were distributed more widely, it could inspire more of the same.”
