This puzzle tries to throw you off before you even start by saying the answer is not 15.
The expression is:
5 + 5 × 2
Use the standard order of operations. Multiplication comes before addition.
First:
5 × 2 = 10
Then:
5 + 10 = 15
So despite the claim written above the equation, the correct mathematical answer is 15.
The misleading statement is part of the trick. It encourages people to doubt a straightforward calculation and search for a hidden rule that is not actually there.
Answer: 15.
Sometimes the best way to solve a puzzle is to ignore the distraction and follow the rules carefully.
