Which practice is least compatible with careful math work?

• A. Reading directions before starting.
• B. Double-checking your work.
• C. Rushing through without reading directions.
• D. Ignoring units and labels.

Answer: (D)

Careful math work relies on units and labels to keep calculations meaningful. When you know what each number represents, you can tell if you’re adding apples and oranges or if two quantities truly belong together, and you can convert units correctly when needed. This framing helps you spot mistakes and understand what your final answer actually tells you. Ignoring units and labels breaks that connection entirely. Without them, numbers lose their meaning, so you might combine incompatible quantities or end up with an answer that doesn’t make sense in the real world, like mixing meters with seconds or mixing different currencies without a clear conversion. That kind of slip is exactly what careful math aims to prevent. Reading directions before you start supports careful work because it tells you what to compute and what units or forms are expected. Double-checking your work helps catch arithmetic or setup errors. While rushing through and skipping directions is also a bad habit, the most direct threat to careful math is neglecting units and labels, which undermines the validity of the entire calculation.
