This simple-looking equation is designed to make people rush.
The expression is:
10 + 10 × 2
According to the standard order of operations, multiplication comes before addition.
First calculate:
10 × 2 = 20
Then add the remaining 10:
10 + 20 = 30
So the correct answer is 30.
The reason many people choose 20 is that they start adding from the left before completing the multiplication. But addition must wait until multiplication is finished.
Answer: 30.
It is a tiny puzzle, but it is a great example of how one small rule changes everything.
