General Math Strategies
Summary
Mastering mental math for dividing numbers by 5 can significantly enhance calculation speed and efficiency, offering a straightforward strategy that eliminates the need for a calculator.
- Doubling the number you wish to divide by 5 and then dividing by 10 provides the correct answer.
