What strategy helps reduce mistakes when solving multi-step problems?

• A. Solve the problem in your head without writing
• B. Use only mental math
• C. Break the problem into smaller steps, show your calculations, and check units
• D. Rely on a quick guess

Answer: (C)

Breaking a multi-step problem into smaller parts and writing out each calculation gives you a clear plan to follow and a record you can review. This structure helps you avoid skipping steps, which is a common source of mistakes, because you have to show what you did at every stage. It also makes it easier to catch arithmetic slips since you can check each intermediate result before moving on rather than letting an error propagate. Checking units as you go acts as a built-in error detector. If the units don’t align or don’t cancel to the expected final unit, you know something is off and you can fix it before finishing. This habit also helps you confirm that your magnitudes make sense after each step, not just at the end. In contrast, solving in your head or guessing lacks this careful trail and often leads to mismatched units or overlooked mistakes.
