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!
This girl was able to lose 352 lbs and this is how she looks now!
Nikki Weber from America is only 34 years old, but she has weighed a lot since childhood, devouring cakes and burgers without thinking about the consequences.
When the girl grew up, she realized that she had to lose weight and tried to go on strict diets. But every time she broke down, and attacked sweet and fatty foods. And as soon as she began to weigh 650 lbs, she realized that she had to change her life.
Then Nikki practically could not walk and get out of bed without someone’s help, so she moved to the house with her parents, who did not consider her daughter’s problem to be something global and did not try to direct her to a healthy lifestyle. They even came up with a special mechanism that lifted food to her on the second floor.
A program called “My whole 661 lbs” came to the rescue. Nikki was invited to participate in the program. The program supports fat people and tries to help them lose weight. The girl underwent surgery to make her stomach smaller, and nutritionists made up a personal diet.
Nikki was very worried, and doubted whether she could restrain herself and whether she would succeed, but her fears were in vain. She pulled herself together and overcame all fears. After the operation she threw off 198 lbs.
Nikki was able to lose 352 lbs in the end, and underwent another operation to remove excess sagging skin, which weighed as much as 55 lbs.
Now Nikki weighs 198 lbs and is not going to stop there, she does physical activity and walks a lot every day. Nikki herself can not yet believe that she managed to lose weight and turn into a beautiful woman with a normal life.
In the gym, Nikki met her future husband Marcus. They fell in love with each other at first sight.
