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!
The Cooling Power of Cucumbers: A Natural Approach to Reducing Wrinkles
Cucumbers have long been celebrated in skincare for their hydrating and soothing properties. While they may not be a magic solution to all wrinkles, even at 70 years old, there’s no denying that cucumbers offer noticeable benefits for the skin, particularly when it comes to reducing puffiness and refreshing the appearance. So why should you consider incorporating cucumbers into your skincare routine?
Why Cucumbers?
Cucumbers are rich in water, which helps hydrate the skin, and they contain antioxidants like vitamin C and folic acid that help fight against environmental stressors and may reduce the appearance of wrinkles over time. The cooling effect of cucumbers is also perfect for calming irritated skin.
How to Use Cucumbers for Skin Care
Cucumber Slices
- Cut a fresh cucumber into thin slices.
- Lie down and place the slices over your eyes and any wrinkled areas, such as the forehead or around the mouth.
- Leave them on for about 10 to 15 minutes.
While this won’t permanently erase wrinkles, it can help reduce under-eye puffiness and refresh your skin.
Cucumber Mask
- Peel and puree one cucumber.
- Mix the cucumber puree with aloe vera gel for an extra soothing effect or honey for additional moisture.
- Apply the mixture to your face and leave it on for about 15-20 minutes before rinsing with cool water.
This can help soothe, hydrate, and tighten the skin, making wrinkles less noticeable.
Cucumber Juice Toner
- Grate a cucumber and strain its juice.
- Apply the cucumber juice to your skin using a cotton ball.
- Let it sit for about 10 minutes, then rinse with cold water.
This toner can help tighten pores and refresh the skin.
Realistic Expectations
While cucumbers are excellent for hydrating and revitalizing the skin, they are not a miracle cure for wrinkles. Skin aging is influenced by many factors, including genetics, sun exposure, and lifestyle habits. Cucumbers can help reduce the appearance of wrinkles by hydrating and tightening the skin temporarily, but they cannot eliminate wrinkles completely or reverse skin aging.
Conclusion
Incorporating cucumbers into your skincare routine can be a delightful way to refresh and hydrate your skin, reduce puffiness, and give your face a more rested appearance. Regular use, combined with a well-rounded skincare regimen that includes sun protection and healthy lifestyle choices, can help maintain the skin’s youthful appearance. So, while cucumbers might not wipe away all signs of aging in minutes, they are certainly a soothing and beneficial addition to your skincare arsenal.
