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!
DEVASTATING NEWS ON TRUMP LEAVES …
Former President Donald Trump released a brief health report from his doctor, Dr. Bruce Aronwald, asserting that his health is “excellent” and noting weight loss attributed to an “improved diet” and regular exercise.
However, the report lacks critical specifics, such as Trump’s weight, blood pressure, cholesterol levels, prescriptions, and the exact amount of weight lost.
Historically, Trump’s health reports have been vague, often including exaggerated claims, such as being the “healthiest individual ever elected to the presidency,” while omitting important details. In contrast, President Biden provides more comprehensive health reports, though they have not fully alleviated concerns about his age and overall health.
Both Trump and Biden face scrutiny regarding their capability to serve another term due to their age, with polls indicating voter concerns about their fitness for the presidency. Trump has particularly emphasized his cognitive test results as evidence of his mental acuity.
