## How do you round numbers?

Rounding numbers involves adjusting digits to make quick estimates rather than exact calculations. It simplifies complex data, making it easier to work with mentally. While rounding may not give an exact answer, it's useful in everyday tasks like budgeting and decision-making. It helps us make informed judgments swiftly and efficiently.

If you want to round to the nearest 10, for example, you will need to:

• Identify the digit to the right of the tens place:
Look at the digit in the ones place (the digit to the immediate right of the tens place).

• Decide whether to round up or down:
If the digit in the ones place is 5 or greater, round up.
If the digit in the ones place is less than 5, round down.

Change the digit in the tens place according to the rounding decision.
If you rounded up, increase the digit in the tens place by 1.
If you rounded down, keep the digit in the tens place the same.

• Set all digits to the right of the tens place to zero:
After rounding, set all digits to the right of the tens place to zero.

Example: 34 to the nearest 10 = 30. There is a 4 in the ones place, so you round down to 30.
