<\/p>\nChallenge: Can you solve this math problem for middle schoolers \u2013 without a calculator?<\/p>\n
Classic brain training methods are perhaps puzzles like crosswords or sudoku, but I have recently become more attracted to the type of challenge you\u2019ll see below.<\/p>\n
These puzzles have been flooding the web lately, probably because they are really fun!<\/p>\n
These are old classic mathematical problems. When you were in middle or high school.<\/p>\n
These math problems are more fun when you find yourself trying to remember the math you learned as a child.<\/p>\n
Can you figure out the correct solution?<\/p>\n
At the top of the picture, we see the task and then four possible answers.<\/p>\n
Which solution do you think is the correct one?<\/p>\n
<\/p>\n
How did you come up with it?<\/p>\n
Take your time and think about it to find the correct solution.<\/p>\n
Done? Below you can check if you picked the right number!<\/p>\n
A<\/p>\n
B<\/p>\n
C<\/p>\n
The correct answer
\nThe correct answer is B: 12.
\nWhy is 12 the correct answer?<\/p>\n
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.<\/p>\n
Then we are left with a simpler math problem: 3 + 9 \u2013 3 + 3<\/p>\n
The answer is therefore 12.<\/p>\n
Did you pick the correct number? Congratulations!<\/p>\n","protected":false},"excerpt":{"rendered":"
