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!
Do you remember these? Many finds mysterious tools in his grandparents’ home
A young man was recently going through his grandparents’ old things after they passed and showed an interesting find to a friend of his.
The two could not tell what these metal objects could possibly be until the found some information online.
The metal sticks are actually nutcrackers! Likely from the 1940’s or 1950’s, this type of nutcracker would be used to dig the actual nut out of a shell.
They help to get to the edible portion of any nut, but are especially common to help one properly eat a chestnut.
Nutcrackers like this were often in similar sets of seafood tools that included implements for cracking the shells of shellfish in addition to picks for pulling out the meat.
The nutcrackers could also often been found with a matching wooden bowl designed to look like a chestnut.
Many of us and our grandparents had similar tools at home, along with the fond memories that go with them!
Did you ever have nutcrackers or picks like this? Tell us about your favorite memories of them in the comments!
