This math riddle looks simple, but the order of operations is what decides the correct answer.
The expression is:
7 + 4 × 2 − 3
Multiplication comes first:
4 × 2 = 8
Now solve the remaining expression from left to right:
7 + 8 − 3 = 12
It is easy to get a different answer if you calculate everything in the order it appears.
Answer: 12.
