Problem: Rounding Numbers to the Nearest Ten

The task is to round each given number to the nearest ten. Here's how we solve it step by step:

#### Steps for Rounding to the Nearest Ten:
1. Identify the digit in the ones place (the last digit of the number).
2. If the digit in the ones place is 5 or greater, round up by increasing the tens digit by 1.
3. If the digit in the ones place is less than 5, round down by keeping the tens digit the same.
4. Replace all digits to the right of the tens place with zeros (though in this case, we only need to write the rounded number).
