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.

Shocking Moments at the Olympics: Athlete Scores Zero in Diving
There are usually moments of success and disappointment during the Olympics. This year is no exception, with competitors vying for gold hailing from all across the world. But some sportsmen are more unfortunate than others in their circumstances. In one such instance, an Olympic diver’s perfect score startled onlookers.
Olympic women’s 3m springboard diver Alison Gibson of Team USA produced a devastating performance in the preliminary round. Her feet collided with the springboard on her debut dive, resulting in an agonizing error that left the spectators in shock. Sadly, the impact damaged her form, and she placed last among the 28 participants. She was disappointed to learn that she received a score of 0.0 for the dive from the judges.
Later on, Alison talked about the discomfort she felt during the dive. She’s still determined to keep doing what she loves in spite of the setback. She wants everyone witnessing to understand the perseverance required to move forward even when things don’t go according to plan. Alison thinks that every experience can be used to grow and learn, and she wants the athletes of the future to know that they can persevere bravely through difficult times.
These kinds of situations serve as a reminder of the highs and lows of the Olympic Games. In addition to applauding the wins and celebrating the successes, we should recognize the tenacity and will displayed by sportspeople like Alison Gibson. Their experiences encourage us to persevere and never give up in the face of difficulties.
Now let’s examine a few more noteworthy Olympic moments:

A chaotic 5000-meter race
During the 5000m race, a number of competitors staggered and fell face down onto the track, causing mayhem. Hugo Hay, a French runner, and George Mills of Team GB were among them. After the event, Mills had some harsh words to say to Hay, demonstrating the players’ intensity and rivalry.
