The correct answer is -30. At first glance, the equation may look easy, but the trick is remembering the proper order of operations. Many people solve the expression from left to right and accidentally arrive at the wrong result.
According to the PEMDAS/BODMAS rule, multiplication must be completed before subtraction. So instead of subtracting first, begin with 6 × 6, which equals 36. The original expression then becomes 6 − 36.
Now there is only one calculation left. Subtracting 36 from 6 gives -30. Therefore, the correct answer is -30.
If you got the answer right on your first try, well done! If you didn’t, don’t worry—these puzzles are designed to catch people who forget the order of operations. Sometimes, even a simple-looking equation requires a second look.
