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!
Celine Dion puts on impromptu performance backstage at the Grammys amid battle with stiff person syndrome
Celine Dion not only shocked everyone by performing unexpectedly backstage at the Grammy Awards, but she also made a surprise appearance to present Album of the Year.
Dion, 55, has maintained a low profile since disclosing her condition in December 2022 in order to combat stiff person syndrome.
In the video, Sonyaé—who is up for a Grammy—and Dion dance to the beautiful harmony of their voices.
The singer of “My Heart Will Go On” made her first appearance in public since November, when she attended an NHL game with her kids. She also made a surprise appearance at the Grammy Awards.
Although there are rumors that Dion’s voice isn’t getting better in a way that would allow her to perform or record again, it appears that she can still hit the notes that we are all familiar with.
After disclosing her illness, she postponed the remainder of her tour dates, raising doubts about her ability to give a complete performance.
Celine, you have our undying love and support.
