Rounding Definitions and Rules

  • Rounding: The process of adjusting the digits of a number to make it simpler and easier to work with while keeping it close to the original value.
    • Nearest Hundred Rule:
    1. Identify the hundred's place digit in the number (for 4,532, it is 5).
    2. Look at the digit to the right (the ten's place, which is 3 in this case).
    3. If this digit is less than 5, round down (keep the hundred's place digit as is); if it is 5 or greater, round up (increase the hundred's place digit by 1).
    4. Change all digits to the right of the hundred's place to zero.

Example Calculation

  • For 4,532:
    • Hundred's place digit: 5
    • Ten's place digit: 3 (which is less than 5, so round down)
    • Resulting Rounding: 4500
