Classic brain-training puzzles often look simple at first glance—crosswords, Sudoku, and the like—but recently, I’ve found myself drawn more to the kind of challenges you’ll see below.
They’ve been circulating all over the internet lately, and it’s easy to see why—they’re quick, fun, and surprisingly addictive.
These are classic school-level math problems, the kind you once solved in middle or high school. The real challenge isn’t difficulty—it’s remembering the basic rules you learned years ago.
Let’s see how well you remember.
Can you solve this tricky expression using only standard school math rules?
1 + 1 + 1 – 1 × 2 – 0 = ?
A
B
C
Answer:
First, apply the correct order of operations (multiplication before addition and subtraction).
1 × 2 = 2
Now rewrite the expression:
1 + 1 + 1 – 2 – 0
Simplify step by step:
3 – 2 = 1
So the final answer is: 1
It looks simple, but the key is not rushing—many people forget to handle multiplication first.
Did you get it right?
