Using Estimation and Mental Math

Quick Calculations

Estimation and mental math can help you check your work and answer questions faster. Round numbers to make calculations simpler and use mental shortcuts for basic operations. This saves time and reduces careless mistakes.

Examples

  • Estimate \(49 \times 21\) as \(50 \times 20 = 1000\) to see if your answer is in the right ballpark.

  • Add up multiple-choice options quickly to eliminate choices that are way off.
