The correct answer is -30. While the equation may seem straightforward at first glance, the key is following the proper order of operations. Many people rush through it and end up with the wrong answer by solving it from left to right.

According to the PEMDAS/BODMAS rule, multiplication must always be completed before subtraction. This ensures mathematical expressions are solved correctly and consistently, no matter who is calculating them.

Start by multiplying 6 × 6, which equals 36. Once the multiplication is complete, you’re left with the expression 6 – 36. This is the only subtraction you need to perform.

Finally, subtract 36 from 6, giving -30. So the correct answer is -30. If you got it right on your first try, well done! If not, don’t worry—these simple-looking puzzles are designed to catch people who forget the order of operations.
