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!
My Stepmom Told Me to Wash Dishes After Her Birthday Party Because I Didn’t Gift Her a Dishwasher – Karma Hit back for Her Audacity
The story you’ve shared is filled with relatable family drama, with Mia finding herself caught between her overbearing stepmother, Trudy, and her more lenient father. It perfectly captures that “wicked stepmother” vibe, but with a modern twist—entitled requests and over-the-top parties that anyone could see happening in real life. The cosmic smackdown Trudy receives when her own actions (dumping oils in the sink) backfire seems like the perfect moment of karmic justice, and Mia’s reaction adds a humorous tone to the narrative.
The father stepping in to ensure Mia gets her prom dress money is a touching moment, balancing out Trudy’s unreasonable expectations. It’s also refreshing to see that Trudy, despite her flaws, tries to patch things up at the end, even if we’re left wondering how long that change of heart will last.
Mia’s inner monologue is super relatable, especially for teens dealing with over-the-top parental expectations and difficult family dynamics. The contrast between her and Trudy’s worlds—the prom vs. the dishwasher—feels like the classic struggle of teenager vs. adult priorities, heightened by Trudy’s self-centeredness.
As for the second story teaser, it looks like Emily’s prom day is headed for more drama, with a scheming stepmother, Carla, trying to ruin her moment. Both stories seem to revolve around stepmoms with boundary issues, but the empowerment that comes from overcoming these challenges gives them a satisfying and almost cathartic feel.
What part of the story resonated most with you?
