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.
Did you pick the correct number? Congratulations!
They blocked off the road after realizing what this elephant was carrying with its trunk
Deep within the animal realm, among the verdant forests and huge savannas, lives a unique species that goes by the name of elephant. Scientists and environmentalists have long been fascinated by these gentle giants. After years of intensive study and close observation, we now know that elephants have a profound emotional range and a grieving process that is remarkably comparable to our own.
George Wittemyer is a committed conservation biologist from Colorado State University who has spent a large amount of his professional life researching elephants. He once gave National Geographic a glimpse into his observations, illuminating the complex and mysterious mechanisms by which these majestic creatures deal with the death of a fellow herd member.
“Elephants have respect for their dead,” Wittemyer stated, “but their interaction with their dead is not something we fully understand.” Researchers have been intrigued by this mysterious part of their behaviour, which shows that when these animals experience the loss of one of their own, they react from deep-seated emotions.
Recently, Twitter user Parveen Kaswan released a video that revealed this fascinating discovery, underscoring the depth of elephants’ emotional intelligence and their distinct grieving process. The film shows a scenario on a peaceful road where all of the traffic has stopped and people are staring at an incredible sight.
A magnificent herd of elephants is crossing the street with a grace that is appropriate for their size and harmony. One elephant in particular sticks out in the parade, softly holding something in its trunk. Viewers, intrigued, quickly discover that the elephant is bearing a young, dead elephant calf, which is inert.
The herd stops quite solemnly, and the elephant carrying the small load carefully lays the dead calf on the ground. The others assemble around, creating a circle of respect. This scenario is quite moving; it conveys a sense of shared sadness and mourning.
The title of the video, as Parveen Kaswan so eloquently put it, “The family just don’t want to leave the baby.” Their behaviour is reminiscent of the solemn cortege of a deceased person.
The elephants continue to amaze and astound researchers and viewers alike with their level of emotional depth as they exhibit an instinctive reverence for the deceased and an understanding of the great grief they have experienced.
As they go on their trek, a second elephant comes up and tenderly cradles the dead calf in its trunk. Elephant herds are emotionally connected to one another, and this display of deep grieving and solidarity emphasises how capable elephants are of feeling loss and sadness.
This will move you !! Funeral procession of the weeping elephants carrying dead body of the child elephant. The family just don’t want to leave the baby.
The film serves as a moving reminder of the extraordinarily emotional lives that elephants lead and is evidence of the strong bonds that exist among animals. It’s a tale that connects our worlds and serves as a moving reminder of the intricacy and beauty of nature. Please spread the word about this post on Facebook to your loved ones so that others can also be moved by the moving scenes shown in the film.
