👉 One common mistake in math is incorrectly applying the order of operations, often leading to wrong results. For example, consider the expression 2 + 3 × 4. A common error is adding first (2 + 3 = 5) and then multiplying (5 × 4 = 20), which gives an incorrect answer of 20 instead of the correct 12. The proper order follows PEMDAS/BODMAS: parentheses/brackets, exponents, multiplication and division (from left to right), addition and subtraction (from left to right). Thus, 2 + (3 × 4) equals 2 + 12 = 14. This mistake can easily lead to confusion, especially in more complex expressions involving multiple operations.
