**What is rounding?**

Rounding means reducing the digits in a number while trying to keep its value similar.

*For example:*Number 62 is between 60 and 70, but when it rounded to the nearest ten is 60, because 62 is closer to 60 than to 70.

**How to round numbers?**

- Decide the place value (the last digit to keep). Exp: tens, hundreds, thousands etc
- Leave it the same if the next digit is less than 5. (Rounding down)
- Increase it by 1 if the next digit is 5 or more. (Rounding up)
- Lastly, replace the removed digit with “0”.

**Example: Round 34 to the nearest tens.**

- We want to keep the “3” as it is in the tens position.
- The next digit is “4” which is less than 5, so no change is needed to “3”
- As a result, the answer is “30”, 34 gets rounded down.

**Example: Round 48 to the nearest tens.**

- We want to keep the “4”.
- The next digit is “8” which is 5 or more, so increase the “4” by 1 to “5”.
- As a result, the answer is “50”, 48 gets rounded up.

So, when the first digit removed is 5 or more, increase the last digit remaining by 1.
