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!
CBS Mornings’ Gayle King, 69, makes debut as cover girl for Sports Illustrated Swimsuit issue
Once she decided to go through with the photoshoot she set a few ground rules. She wasn’t going to starve herself and she didn’t want any retouching of her photos, except for “a few dimples on her thighs.”
“My grandmother said to me [when I was little], ‘Mother nature was not as kind to you as she was to other little girls. Maybe you need to start wearing makeup.’ I just never saw myself this way.”
She added, “I know what I look like before I go into hair and makeup, so it’s hard for me to go from that to [the cover]. That’s something I have to process myself.”
King had nothing to worry about.
When she arrived at the photo shoot in Mexico, she said photographer Yu Tsai made her feel like “Beyoncé, Jennifer Lopez, Halle Berry all rolled into one.”
“I felt so comfortable and cared for that I didn’t even have time to feel self-conscious.”
“I never in a million years thought I would be standing here in a bathing suit for Sports Illustrated [Swimsuit], but here I am, which says to me that sometimes people can dream, God can dream, the universe can dream a bigger dream than you can ever think for yourself,” King told Sports
Illustrated. “I would have never thought this was possible. This was nowhere on my bucket list. So I’m thinking maybe it was a dream that I didn’t even know I wanted because now that I’m here, I want it bad.”
Gayle looks amazing! I think it’s wonderful how Sports Illustrated showcases all different ages, body types, and races in their issue. We’re not all the same, and everyone deserves to be represented.
