This viral math puzzle has millions scratching their heads. At first glance it looks easy, but the order of operations (PEMDAS/BODMAS) is what trips most people up.
The correct answer is 25. You do multiplication and division first (left to right): 5 × 5 = 25, then 5 ÷ 5 = 1. Now the equation becomes 5 + 25 – 1 = 29? Wait — actually, following strict left-to-right after exponents: 5 + (5×5) – (5÷5) = 5 + 25 – 1 = 29.
Many rush and get 0 or 5.
