When I first encountered the expression 10 + 10 × 10 - 10, I was tempted to solve it from left to right, simply adding and subtracting as I went. However, I quickly realized that math has specific rules for the order in which operations must be performed—known as the PEMDAS/BODMAS rule (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Applying this, the multiplication step is done first: 10 × 10 equals 100. Then, the expression simplifies to 10 + 100 - 10. Solving left to right, 10 + 100 gives 110, and finally subtracting 10 brings the result to 100. This concept highlights why understanding operator precedence is crucial. Many math errors stem from ignoring the proper order in expressions containing mixed operations. For learners, practicing with similar expressions and using acronyms like PEMDAS can help reinforce the correct procedure. Moreover, calculators often follow these rules automatically, but when working by hand, being methodical ensures accuracy. I found that writing out each step explicitly, as shown above, reduces mistakes and builds confidence. This approach can be applied to more complex expressions as well, sharpening problem-solving skills in math.
